Ball Bearing Sensor – CR20985-004

This sealed ball bearing supports a rotating sensor element within the drive and control systems of Crown electric lift trucks, letting a shaft or sensor target turn smoothly while a speed or position sensor reads it. Precision bearings in sensor locations keep the air gap and alignment consistent, which protects the accuracy of the truck's speed, direction, and motor feedback signals. Running under continuous vibration and load, a worn sensor bearing can introduce play or noise that degrades signal quality and triggers fault codes or erratic drive behavior. A fresh bearing restores true rotation and dependable sensor readings. Confirm the bore, outside diameter, and width match the original bearing you are replacing.
