BRB 400

(Heavy Duty / High Temperature Grease) It is an E.P. Moly grease specially formulated from complex soap blended with special chemical additives to meet the most adverse conditions in industrial environment. It has a very good affinity towards all the metal surfaces under critical conditions i.e. it forms and maintains a film highly adhesive to the bearing surface reducing friction and wear.


For Ball and Roller bearings operating under high speed and high temperature, King pins, Ball joints, Gears, Linkages, Speed reducers, Stenter fan bearings etc.


-    Heavy duty/High temperature grease.
-    Highly adhesive.
-    Reduces maintenance downtime.
-    Operates effectively under adverse conditions.
