VSE Front Lubrication Unit for Ball Screw Assemblies

Content

With the new VSE front lubrication unit for diameter 20, 25, 32 and 40 ball screw assemblies, Rexroth dramatically lowers ball screw total cost of ownership. Requiring no maintenance, and eliminating the need for a central lubrication system, the new front lubrication unit provides up to 300 million revolutions or 5 years of optimal lubrication under normal operating conditions. The plastic VSE for driven screws combines an open-pore foam with an oil tank.

Only one VSE per ball nut is required for optimal results, giving machine builders a tremendous flexibility to integrate the space-saving VSE into existing assemblies. The unit is compatible with almost all catalog ball nuts and can be used in both horizontal and vertical applications. Rexroth supplies the front lubrication unit completely assembled and ready to install in connection with a completely machined ball screw assembly.

Optimizing lubrication at the minimum quantity required over the entire functional ball screw lifetime protects the environment and reduces the time and costs spent on maintenance in many applications with typical production environments, such as automation and handling, electrical and electronic systems, and medical engineering.
