Reliable Graphited Greases are calcium base greases containing graphite Flake as filler These greases are used for general lubrication under comparatively high load and relative displacements of inter acting surfaces.
Reliable Graphite Greases has three grades (Gr.-I, Gr -2, Gr -3) and these meets IS: 508-1987 specification(Reaffirmed 1993). These greases are recommended for leaf springs, hydraulic rams, plungers, slides, elevator cables, and pantograph pans and as protective for steel wires ropes and certain anti-seize purposes in temperate and tropical climates.
