There are advantages to using RBS for ball screw repairs.
- RBS has been primarily in the ball screw business since Ian McBain founded the company in 1973. Ball screws have always been our focus, allowing us to focus on improvements pertaining to ball screw manufacturing and repair. We're experts in both fields.
- We offer free evaluations.
- When a customer calls RBS, they get a real person on the receiving end of the call. The customer service people at RBS have the knowledge and experience to help the customer with their issue.
- RBS is an American company, located in Illinois.
- RBS has a state-of-the-art facility, recently expanded upon and equipped with new machines and processes. This allows us to control all aspects of manufacturing to aid the repair function which includes:
- Raw material inspection
- CNC Centerless grinding for the raw stock, prior to roll
- Roll machines
- Straightening operation
- Heat treat operations
- Annealing
- Cut off saws
- Machining the end journals (lathes, auto feed and product ejection)
- Grinding end journals
- Milling (CNC Mills)
- Inspection
- Our in-house capabilities allow a 24-hour turn-around time for repairs.
- Lead time for the average repair is 2 working days. In the event the customer requires shipment same day, this can be accomplished with an expedite fee.
- We repair all Imperial (inch) sizes from a .500” inch diameter to 6” inch diameter as a norm. Larger if the requirement dictates.
- RBS repairs all metric sizes from 12mm to 300mm dia. and lengths up to 50 feet (15.24 meters).
- We clean and repair the internal cross-over returns for the internal return nut systems.
- We repair the inner bearings in the bearing end supports (or replace as needed).
- RBS repair will analyze and fix solid structure return tubes and the deflectors that change the trajectory of the bearings as well as the split return tubes with finger extensions.
We repair all makes and models of ball screws
In the event the screw/nut/bearing support assembly cannot be repaired, RBS has the ability to reverse engineer the unit and send our customer a new model.
When the ball screw units come into the RBS facility for repair, the following tasks are performed:
- The units are photographed as received. This allows us to identify nut direction. It also allows us to record the condition of the unit prior to rebuild.
- Inspected for running condition and evidence of any apparent moment load on the ball nut.
- Complete disassembly of the unit. Photograph parts, if needed.
- The ball screw is cleaned and visual inspection under magnification of all components is performed.
- Ball screw and ball nut raceways are checked for wear.
- The ball screw is inspected for straightness and lead accuracy.
- The unit is straightened.
- Surface defects are repaired.
- Unit is photographed to note current condition.
- Screw journal diameters are inspected for size and finish.
- Spline diameters, Radius, V-threads, and keyways are also inspected.
- The ball return system in the ball nut is inspected for damage.
- The bearings are examined and recorded.
- The ball nut ID is examined and checked for moment loading.
- Screw straightness is assessed.
- The engineering analysis is then communicated to the customer.
The above actions happen rapidly, allowing for same day or 24 hour turn-around time for repairs.
