9.3.4.1

Replacing bearings in explosion-proof machines

●

When changing the bearings, renew the sealing rings and only use original Siemens

spare parts.

●

For radial sealing rings with dust protection lip (DIN 3760-AS), completely fill the spaces

(100%) in the sealing ring as well as in the bearing shield hub with a suitable grease.

9.3.4.2

Bearing bushes

Protect the bearings against the ingress of dirt and moisture.
