SKF FRB 12.5/160 Locating Ring -, 80mm ID

The bearing seating in the housing is sufficiently wide to enable the bearing to be displaced axially
Bearings which are to locate a shaft axially in both directions (locating bearings) must always be fixed axially in position in the housing bore by locating rings at both sides
The locating rings are identified by the prefix FRB followed by figures giving the width/outside diameter in millimetres, e.g. FRB 12.5/130
