BRO-LUB® is a maintenance-free version of BRO-MET®. The diamond-shaped lubrication pockets are filled with graphite, a solid lubricant. The concept of the BRO-LUB® bushings is derived from the LUB-MET® material that has already been in the bearings market for many decades. With every movement of the shaft, tiny particles of the solid lubricant are being evenly distributed over the contact surface between the shaft and bushing. Thus, building up a sliding layer.
BRO-LUB® is a very good upgrade, especially for applications that normally require high greasing intervals (excessively contaminated applications), are difficult to carry out maintenance due to the location or where automated grease lines continuously fail.
It is necessary that an initial greasing is applied during installation to initiate the build-up of the solid lubricant layer.
BRO-LUB® also only can run completely maintenance-free if a non-corrosive shaft material is used.
Otherwise, the shaft would corrode and develop an abrasive sliding surface. This would tremendously decrease the lifespan of the bearing.
The dimensions of BRO-LUB® are according to DIN 1494 / ISO 3547 and are identical to BRO-MET®.
Typical applications are for agricultural machinery, brakes and certain construction machinery.
