From size 25 to 63 the gears are always supplied in the Universal position and may therefore be mounted in virtually any position, from size 75 to size 130 if the positioning required differs from B3 it should be specified. In particular, when a gear constantly in place B3 is usually to be mounted in positions V5 or V6, the bearing positioned in the upper part should be lubricated using ideal CHPC/CHM – WORM GEAR WITH PRE-STAGE MODULE grease that ensures proper lubrication. We’ve tested Tecnolubeseal POLYMER 400/2 grease.
