8 lnstallation and maintenance
8.9 Lubrication
The gear pairs are oil-bath lubricated, the bearings are either oil bathed or splashed or lubricated ufor ilfer
wi,h grease. For some mounting positions with continuous duty at high speed, an expansion tank is foreseen:
consult us.
Sizes 001A ... 021A. gear reducers are supplred filled with PAO synthetic o¡l having viscosity 320 cst
(at 40" C).
lmportantl:verify mounting position, keeping in mind that if gear reducer is installed in a mounting position
differing from the one stated on name plate, ¡t could need the addition of the difference between the two
lubricant quantities. 1n any cases, always check the correct oil quantities through the transparent level plug.
Sizes 022A ... 0854: gear reducers are supplred without oil; before putting into service, fiil to the specified
level'' with synthetic or mineral oil (see table below).
Consider the lubrication inlerval stated in the table for all re-lubrication operations, emptying the gear reducers
from the exhausted oi1, executing a wash with c ean o¡l of the same type to be used also for the re-filling of the
gear reducer up to levell).
Use only lubricants of the same type stated on lubrication nameplate.

Never nrix different nrakes of synthetic oil; if orl-change involves swÍtching to a type drfierent from that used
hithe¡o, then grve the gear reducer a through clean-ou1. Polyglycol basis synthetic lubrcants must not be used.
Bearings with independent lubrication
Usuaiiy rhe bearings are automatically and continuously lubrcated (oil-bathed or splashed) with the same
lubncant of gear reducer. However for certain gear reducer rn vertical mountrng posrtions V1, V3 and horizontal
mount;ng pos¡tions 851, 852 the upper bearings have independent lubrication, with special grease for ulong
lrfe, ubrication n absence of erternai pollution.
