M ining C r ushing T r ansfer P r ocessing NTN Mining Application 12 BEARINGS with SOLID GREASE Features Solid g rease is a lubr icant essentially composed of lubr icating g rease and ultr a highmolecularw eight poly eth ylene Solid g rease has the same viscosity as ordinar y g rease at nor mal temper ature b ut as a result of a special heat treatment process this g rease solidifies retaining a large propor tion of the lubr icant in it By this solidification the g rease does not easily leak from the bear ing e v en when the bear ing is subjected to strong vibr ations or centr ifugal f orce 1 Reduced lubricant leaka g e Because the base oil is retained in a solid f or m it is less lik ely to leak out of the bear ing Dur ing oper ation temper ature r ise andor centr ifugal f orce will cause a gr adual release of the base oil into the rolling surf aces Eliminating g rease leakage from the bear ing ensures a consistent supply of lubr icant and pre v ents contamination of the surrounding en vironment 2 Superior lubrication Bear ings with solid g rease resist g rease leakage prolonging bear ing lif e in applications where high centr ifugal f orce or vibr ation are present The solid lubr icant does not em ulsify when e xposed to w ater also e xtending both g rease and bear ing lif e 3 Sealing eff ect Though solid g rease protects a bear ing against ing ress of f oreign matters w ater dust etc it is not an eff ectiv e sealing de vice Theref ore f or applications that need reliab le sealing perf or mance w e recommend the use of contact type ru b ber seals deep g roo v e ball bear ings bear ing units or other seals other bear ing types Solid grease bearing f or s wing mac hiner y Solid g rease lubr ication CA T NO 3022E
