From size 25 to 63 the gears are always supplied in the Universal position and can therefore be mounted in virtually any position, from size 75 to size 130 if the positioning required differs from B3 it must be specified. In particular, when a gear constantly in place B3 is to be installed in positions V5 or V6, the bearing situated in the upper aspect should be lubricated using ideal grease that CHPC/CHM – WORM GEAR WITH PRE-STAGE MODULE ensures correct lubrication.
