RBS supplies ball screw product accessories pertaining to mounting, lubrication, safety devices and debris elimination.
RBS manufactures both Standard and Custom mounting flanges to suit the customer's needs. Flange configurations include standard bolt through round, trunnion, custom flats, ported or lubed, square, etc.
If a mounting flange is used instead of the standard v-thread on the ball nut body, it must be permanently attached to prevent disengagement during operation. The two standard methods of retaining the flange is pinning and retaining with a set screw. Commercial thread locking adhesives may also be used (light loads only). It is always recommended that the flange pinning be performed at the factory to assure no metal chips are present after drilling.
The orientation of the flange bolt holes to the return tube components varies with the number of holes in the flange. Unless otherwise specified, the following illustrations represent the standard orientations.
Our product catalog pages detail the type of wiper mounting arrangement for each ball nut model. Brush wipers may require customer supplied retention primarily on the V-thread end of the ball nut (on models that do not have internal wipers and snap rings). A stamped flange retainer is available for many models that do not have internal snap rings for wiper retention (see data pages for available sizes).
Lubrication of the ball screw assembly is extremely important to maintaining optimum efficiency and life. The ideal access point of introducing the lubrication is directly into the ballnut. Below we have illustrated a number of methods that have been utilized to ease the process of lubricating the ballnut. Should none of the methods apply to your application, please consult factory.

RBS Multi-purpose Synthetic Grease
AVAILABLE IN 14 OZ. CARTRIDGES
NOTE: To achieve optimal grease performance, it is recommended that the machine components should be kept in careful alignment, the operating environment should be kept clean, and the assembly should be periodically inspected for proper lubrication quantity and integrity.
Proper lubrication along with reducing/eliminating foreign contamination are essential for preventing premature catastrophic failure. The R/B/S multi-purpose PTFE fortified synthetic grease has been specifically formulated with extreme pressure and anti-wear additives to reduce rolling element friction, wear, and provide noise damping characteristics. The excellent mechanical stability allows for compatibility with ferrous metals, non-ferrous metals, and most engineering plastics.
Consult the factory for specific material interactions. R/B/S recommends this grease be used for ballscrew, ACME screws, bearing mount, and other applications requiring excellent hydrodynamic lubrication.
