Page 4: ...The close concentricity of this mounting spigot to the bearing diameter allows parallel path rollers and thus avoids web tracking problems No appreciable force should be transmitted through the four fixing bolts See the Transducer Dimensions drawing for full details 2 4 Bearing Lubrication The bearing normally fitted by CMC Controls is without seals and has only the bearing manufacturers preservat...
