Bearing for swing bridge - has rubber or plastic sliding surfaces lubricated by grease supplied at high pressure

The pivot bearing of a swing bridge has a bearing surface (4) of rubber or plastic such as PTFE sliding against a metal surface (10). In conventional bearings of this type the initial charge of lubricating grease leaks away from the the joint surface resulting in an increase in friction. In order to...

Zusammenfassung:The pivot bearing of a swing bridge has a bearing surface (4) of rubber or plastic such as PTFE sliding against a metal surface (10). In conventional bearings of this type the initial charge of lubricating grease leaks away from the the joint surface resulting in an increase in friction. In order to maintain or renew the supply of grease a tube (1) is fitted which connects the central hole (2) with a connector (3) on the outer ring (6). A fresh supply of grease can then be injected under pressure through the tube to reach the sliding surfaces.
