20th Century Machine:

20th Century mfg in the USA is a high-quality precision ground ball screw. Replacements are hardly ever on the shelf and ordering a new one can take over 3 months. We can repair any model 20th Century ball screw in less than 5 days and we’ll save you over 60% from ordering new. All 20th Century rebuilds are backed by our 36 months (parts and labor) warranty.

Bosch Rexroth:

Bosch Rexroth ball screws are very good at keeping replacements on the shelf, although I will warn you they can be very expensive to replace. The main problem we see with Bosch repair is that the plastic return (that re-circulates the ball bearings) usually breaks or wears down and all of the balls fall out. Dirt and debris are the main problems along with lack of lubrication. Bosch Rexroth will not sell the returns, they want you to purchase a complete unit for a large amount of money. We can repair any Bosch Rexroth ball screw in just 2 to 4 days. We have a wide range of nuts and returns on the shelf for immediate use. Call us with the length and diameter you have and we can give you a quote for repair right over the phone. Bosch Rexroth turn around times are usually under one week and we do offer a 24/48 hour emergency delivery option on all projects.


The typical cost for most Bridgeport ball screw repair is $500 to $950 depending on how badly they are worn. We have some Bridgeport screws on the shelf for conversion kids or exchange. The usual problem is they are out of tolerance and most users over compensate the settings.

CNC Machine:

The majority of ball screws we repair are for CNC machines in standard and metric sizes. We can completely rebuild your CNC ball screw in 3 to 5 days and all of our work is guaranteed for 36 months from the delivery date covering all parts and labor. If your CNC ball screw isn’t working properly, your machine isn’t making you money the way it’s supposed to. Let Accurate Machine repair your CNC ball screw and get you back into production.


Typical cost for most Bridgeport ball screw repair is $500 to $950 depending on how badly they are worn. We have some Bridgeport screws on the shelf for conversion kids or exchange. The usual problem is they are out of tolerance and most users over compensate the settings.

Giddings and Lewis:

Giddings and Lewis make a very high-quality ball screw that is very original in design. The pickup/returns and nut are extremely high quality and the main problem we see is loss of tolerance or backlash issues. These large ball screws are never in stock as a shelf item and always need to be custom made for your application. We can repair any Giddings & Lewis ball screw to perform like new in just 5 days and we will save you over 60% of the price of a new assembly. We precision OD grind your ball screw with a larger diameter raceway and precision ID grind the nut to +/- .0005 of each other. We install new grade 10 chrome steel balls and lap all parts to mate with each other. Backlash is kept at dead zero and tolerances are up to .0003 per linear foot of movement.

Haas Machine:

Haas has a few on shelf ball screws for immediate purchase and they can be expensive to replace. We have a wide range of Haas ball screws available for immediate exchange. We can also repair any Haas ball screw in 5 days or less and we can save you over 60% from buying new. All Haas ball screws are fully guaranteed for 36 months from the install date covering all parts and labor.

Hiwin Machine:

We have Hiwin ball screws, nuts, and replacement parts on the shelf for most of their models. We can do an immediate exchange or offer a complete rebuild service. Contact our sales department for pricing on your model number. Hiwin manufactures have great products that are relatively cheap to replace. The problem is the delivery time which can exceed 3 to 4 weeks.

Injection Molding Machine:

Most injection molding machines have updated the old hydraulic cylinder with a ball screw for opening and closing the clamp on the injection machine. Over time, the ball screw wears down without any signs of problems until it’s too late. Replacement cost can be in the neighborhood of $10,000.00 and they are never in stock. It’s always an 8 to 12-week wait. Unlike most ball screws, this isn’t a high precision ball screw repair that moves in .0001 increments. It moves a heavy clamp/platen to open and closed positions and what is most important is repeatability. We’ve repaired hundreds of ball screws for injection molding machines. Let us get you back in production in just 5 to 7 days and save you 50% or more.

Komo Machine:

Woodworking and router ball screws. The main problem we see is that these nuts get packed with wood chips and other debris clogging up the returns and wearing out the ball size. The majority of Komo ball screws are not on the shelf and can easily exceed 8 weeks for delivery time. We can rebuild yours to work like new in just 3 to 5 days (over 12 feet can take one to two days longer). We also modify the wipers with a larger and wider backup that keeps dirt & chips out of your nut and works better than the factory ones.

Mag Cincinnati:

Mag Cincinnati ball screws are not on the shelf and need to be custom made to your machine. Our delivery on any Mag Cincinnati ball screw will never exceed 6 days. Backlash, loss of tolerance and noise are the problems we see most often on Mag Cincinnati screw. They are easily repaired to exceed OEM specifications and tolerances with a 50% savings from ordering new.

Mazak Machines:

Mazak makes a very high-quality machine and replacement can take 6 to 8 weeks. You can usually find a used one on the internet or auction sites, but there is no guarantee on how it will perform. The most common problem with Mazak ball screws is that over time the screw and nut will get incredibly dirty and sticky from the coolant and the nut gets clogged with chips and debris from the machine. Over time the nut will wear out along with the balls causing backlash, loose, loss of tolerance, etc. With precision OD & ID grinding we can restore your Mazak ball screw to work like new. We will save you 60% or more from replacement cost and downtime is only a few days.

Morbidelli Machines:

High precision and fast-moving ball screw. Morbidelli manufactures a high-quality ball screw that will last a very long time if maintained properly. The only problem with Morbidelli ball screws is the time it takes to order a replacement, it can reach 4 months because they are all custom made. If you are experiencing problems with your Morbidelli ball screw, call us with the exact errors you are dealing with and we can get you a price right over the phone. Delivery time never exceeds 5 working days.

Mori Seiki Machine:

A high-quality machine and ball screw. Most production shops use this as a favorite. The most common problem is worn out in one section, where you’ve used it the most. In one spot, it works perfectly and in others, it’s loose and will not hold tolerance. With precision OD grinding of the ball screw shaft to accept a larger diameter ball, we grind passed all the wear making the thread an even size throughout the length of the screw. All Mori Seiki ball screws are fully guaranteed 36 months with all parts and labor.

NSK Machines:

NSK is another high-quality ball screw that is readily available for purchase in 2 or more weeks. Replacement cost can be expensive. We can rebuild your NSK ball screw to exact OEM specifications and tolerances in 3 to 5 days. We do not carry any exchanges for NSK ball screws


Small and sturdy. SKF ball screws last a long time and are widely used in different machine types. The most common problem is the balls fall out making the nut useless. You don’t know you had a problem until it all falls apart. We can manufacture replacement pickups & returns, and the OEM will not sell single nuts, replacement parts, etc. The only option is the replacement at a 5-week wait.

NTN Machines:

These small ball screws are readily available on the shelf overseas, but delivery times can easily exceed 10 days. NTN manufactures a decent screw and the main problem is normal wear. We can repair any size NTN ball screw in just 5 days or less and save you 60% or more from ordering a new one. Get your machine back into production and save money with Accurate Machine.


Okuma manufactures its ball screws in Japan and delivery time for a replacement is 4 to 6 weeks for shipment and another 2 weeks for customs. We can rebuild your Okuma in under one week and we will save your company a considerable amount of money. Okuma is high-quality and last a long time, but you can’t have your machine down for 8 weeks waiting for a replacement to get here. We can rebuild your Okuma ball screw to meet or exceed factory tolerances with a 36 month warranty

All of our work is fully guaranteed to perform like new for 36 months covering all parts and labor. We work with all manufacturers in inch and metric configurations.

Rolled Thread:

A rolled thread ball screw is NOT a high precision ground ball screw. It works exactly the same but a rolled thread ball screw will not hold the same tolerances as a precision ground ball screw. They can easily be repaired in 3 to 5 days and we can save you over 60% from ordering a replacement. All rolled thread ball screws come with 36 month warranty that covers parts and labor.

Star Machines:

Star ball screws are made in Germany and are never in stock. They can be ordered, but you will wait for 7 weeks to get a new one. The #1 problem we see with Star ball screws is that the plastic return on the nut gets broken or worn down and all the balls fall out. It’s a small part under 1/2 in diameter and it’s made out of plastic. The OEM will not sell these returns or nuts separately, you have to purchase new. We can save you a lot of time and money with a complete ball screw rebuild. We replace the plastic return with an aluminum bronze return that is a lot stronger and will outlast the original plastic. We can repair any Star ball screw in just 3 to 5 days and we’ll save you 50% from ordering a new one. All-Star ball screws are guaranteed for 36 months from the delivery date covering all parts and labor.


THK is a very solid ball screw and they can usually be purchased with a 2 to 4-week delivery. We can save you over 60% from ordering a new THK and deliver in just 3 to 5 days. The most common problem is the nut wears out along with the returns or the balls have fallen out due to the returns breaking. This can easily be repaired in our shop. All THK ball screws come with a 36-month warranty covering all parts and labor.

Toshiba Ball Screw:

Toshiba ball screws are made in Japan and they aren’t readily available. They need to be custom ordered. They claim a 4-week delivery, but we’ve seen it go to 8 weeks or more. We can repair any Toshiba ball screw in just 3 to 5 days and our cost is less than half the price of a new one with 36-month warranty. Save time and money with our Toshiba repair services.

Toyoda Machines:

Toyoda makes a high-quality ball screw in Japan. While they do have most models on the shelf for immediate shipment, delivery times can exceed 10 days and pricing is expensive. We can save you 60% on all Toyoda ball screws and our delivery time is just 5 days. Repair your Toyoda and save time & money.

Warner Swasey:

The old Warner Swasey ball screws cannot be found or replaced. Other companies can make a replacement but it’s a six week minimum wait time. We have parts for most Warner Swasey ball screws from nuts, return tubes and screws and we can get you back up and running fast.

Water Jet:

Some of the most common problems we see with water jet ball screws is that the nut gets compacted with dust and debris from the machine, clogging up the ball returns and wearing out the bearings. Then when you go to interpolate a circle, you get egg shapes because your ball screw is out of tolerance. We can repair any ball screw used in water jet machines in just 3 to 5 days. We guarantee accuracy, precision and repeatability for 36 months covering all parts and labor. We’ll save you 60% or more from ordering a replacement. Call Accurate Machine today for a free estimate.
