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.
Protect the bearings against the ingress of dirt and moisture.
