Lubricant For Gearbox; Electric Motor - Bredel 40-100 Operating Manual

11.2

Lubricant for gearbox

In the majority of the cases a mineral oil ISO VG 150 or ISO VG 220 is recommended. In case of very
low ambient temperatures a mineral ISO VG 100 is advised. In case of high ambient temperatures or
a relatively wide range of ambient temperatures a synthetic oil is recommended. Also in case of very
high loads, resulting in high operating temperatures a synthetic oil is to be preferred.
Use of oil with EP (Extreme Pressure) additives is strongly recommended. Do not mix oils of different
types, i.e. mineral, polyglycol and other synthetic lubricant. Refer to the documentation supplied with
the gearbox for how to care about lubrication. For the food industry as well as for agricultural areas
and nature reserves, special grade lubricants are available.
The table below is an indication for proper viscosity values.
If you have any questions, contact your Bredel representative for advice.
