open-pored foam. This optimized delivery minimizes lubricant
consumption and allows you to achieve lifelong lubrication.
Ecologically sound
The front lube unit ideally combines eco-friendliness with cost-
efficiency. It minimizes oil consumption and keeps the surround-
ings clean. This helps to conserve resources.
Lubrication concept
This logo indicates that the Rexroth Ball Screw Assembly with
prelubed nut and front lube unit are lubed for life.
Note: The front lube unit is not suitable for use with driven nuts.
Lifelong lubrication
The effective life of the Rexroth front lube unit matches the service life curve of the Ball Screw
Assembly. When operated within the recommended load limits, a Ball Screw Assembly equipped with
a Front Lube Unit will require no relubrication, thanks to the optimal delivery of lubricant. Based on our
extensive tests, the lubrication performance of the front lube unit can now be reliably predicted for the
first time. With a Front Lube Unit from Rexroth, a Ball Screw Assembly can run trouble-free for
five years or 300 million revolutions without any relubrication.
