Bearings in high-performance automotive assemblies are required to operate reliably throughout the design service lifetime of the equipment subject to a wide range of temperatures. Sealed bearings employed in such designs must be lubricated for life with additional relubrication neither desired nor possible.
Klübersynth BLP 72-122 was designed in cooperation with leading bearing manufacturers to enable lifetime lubrication of automotive engine pulley bearings. In this highly demanding mounting arrangement involving outer ring rotation with high radial loads, Klübersynth BLP 72-122 provides an exceptionally long service lifetime due to its excellent mechanical shear stability combined with optimised oil release and effective lubricant distribution.
A further benefit of Klübersynth BLP 72-122 is its excellent compatibility with bearing sealing elastomers, particularly ACM. Enabling low-torque starting at minus temperatures, Klübersynth BLP 72-122 eliminates "hoot noise squealing", a phenomenon which is not uncommon in some grease-lubricated pulley bearing designs.
