Kyodo Yushi Unimax R No.2 Rolling Bearing Grease

Product Made in Japan
Manufacturer : Kyodo Yushi
Model: Unimax R

UNIMAX R No.2 is lithium complex grease designed to provide excellent heat resistance and longer service life. Made from carefully selected refined mineral oil, UNIMAX R No.2 offers wider operating temperature range and possesses grater resistance against softening due to mechanical shear than conventional lithium grease. These properties allow the grease to better satisfies the lubrication life requirements for railway motor or axle bearing grease. UNIMAX R No.2 has successfully catered to the latest need of induction motors (VVVF), making a great contribution to realization of higher speed operation and longer maintenance interval. The product has passed the testing for the requirements for DIN EN 12081:2017, a European standard for the lubrication of railway axle bearings.

Characteristics of Unimax R No.2

1.Heat resistance: Using carefully selected purified mineral oil as its base oil, it boasts a wider temperature range of use than conventional lithium soap-based greases. Excels in long lubrication life. Good track record in the main motor application of railway vehicles.
2.Long service life property: Many good track records in high-speed VFD main induction motors and extension of maintenance repeats.
3.Outstanding mechanical stability: The benefit of lithium complex thickener is less shear softening in a bearing, which contributes to better leak resistance performance.
