The SensorMount Indicator TMEM 1500 provides a direct reading of the fit of a SensorMount bearing mounted on a tapered seating. The SensorMount indicator is only compatible with SKF bearings, which are fitted with the SensorMount sensor. These bearings from SKF have designation suffixes ZE, ZEB, or ZEV, e.g. ZE 241/500 ECAK30/W33. The SensorMount indicator provides a numeric value, which guides the user in achieving a reliable bearing fit.SKF bearings fitted with the SensorMount system can also be mounted on adapter sleeves, withdrawal sleeves and hollow shafts. The material composition of the shaft has no effect on the proper operation of the SensorMount system.
