Superior Ball Screw Repair

Welcome to Superior Ball Screw Repair! We have built our company’s reputation around quality and integrity. Our focus is to provide our customers with top quality rebuilt ball screws, excellent customer service, along with the fastest possible turn around time. Choosing between rebuilding or replacing your ball screw can often be a difficult decision for you to make. Sometimes a new ball screw is the right choice depending on price and availability, but usually it is wiser to have it reconditioned, saving you money and down time. Why wait weeks or months for a new OEM ball screw assembly?  Send us your worn or damaged ball screw and have your machine operational again within days. Email or call us toll free at 1-800-594-3404 for an estimate and we will be glad to answer any questions.

From high precision grinding machines to CNC routers, we rebuild them all.

Evaluating Your Ball Screw. The same day we receive your ball screw, we will perform an initial inspection to determine if it is rebuildable and how much it will cost.  There is no charge for our evaluation.  At this time we will contact you and give you a guaranteed price for rebuilding your assembly and the actual date that your rebuilt screw will be shipped.  No further work will be performed until we get your go ahead.

How Much Does a Rebuilt Ball Screw Cost? There are thousands of different types and sizes of ball screws so pricing varies. We can estimate your cost if you provide us with some general information about your ball screw assembly. An estimate of the ball screw’s length and major diameter, the type, make, & model of machine it is in, and the type and make of the ball screw is all helpful information we can use to determine an estimated cost. Typically, you will save 50% or more with a rebuilt ball screw compared to the cost of a new one. Call us for an estimate or send us your ball screw and we will evaluate it for free and give you a guaranteed price up front.

Rebuilding Process. Each ball screw assembly we recondition goes through our step by step rebuilding process. Of course, all ball screws are not alike. Each screw receives special attention where it is needed most. Some ball screws require certain parts replaced rather than reconditioned. Often we must custom make parts for ball screws when replacement parts are not available.

—Inspection: Check the ball screw and ball nut for wear and damage (brinelling and corrosion) on the thread radius. Check the ball screw for straightness. Inspect the ball return system for wear and damage. Check the ball screw for damage on the keyways, bearing journals, and bearing nut threads.
—Repairs: Make any repairs necessary to the ball screw, ball nut, returns, bearing journals and any other worn or damaged parts. Make or replace any parts damaged beyond repair.
—Regrinding and Lapping: Regrind (if necessary) and lap the thread radius of the ball screw and ball nut.

—Cleaning and Refinishing: Clean and refinish all parts to like new condition.
—Assembly: Assemble the ball nut and ball screw to the correct preload using custom sized high quality grade 10 chrome steel balls. Spacers are ground for precision fit. Install wipers (seals) and apply lubrication.
—Testing and Final Inspection: The ball screw is put through a series of tests and then final inspection to ensure quality, precision, and durability.
