R/B/S Grease

Advantages of RBS Multi-Purpose Synthetic Grease

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.

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.



Ball Nut Lubrication

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 ball nut. Below we have illustrated a number of methods that have been utilized to ease the process of lubrication into the ballnut. If none of the methods illustrated below apply to your application, please consult factory.

Lube Port Installed in Flange
Lube Port on Face of Flange
Lube Access Hole in Groove of Mounting Thread
Zerk Fitting Installed on Side of Nut
