Risk of explosion
If you use parts other than the original spare parts, the type of protection can no longer be

● Use only original spare parts for explosion-proof machines; this also applies to
● Commercially available equivalent standard parts such as screws may be used.
Rolling-contact bearings
When ordering roller bearings, in addition to the bearing identification code, the supplementary
specifying code is also necessary for the bearing version. Both of these codes are stamped
on the lubricant plate and specified in the motor documentation, or can also be taken from the
installed bearings.
If roller-contact bearings with an insulated design are installed, use roller bearings of the same
type as spare parts. This will prevent any bearing damage being caused by bearing currents.
