Bearings Inner ring creeps (turns) on the shaft seat
- Most applications have a rotating shaft where the load is unidirectional. This is considered a rotating inner ring load and requires a tight fit on the shaft to prevent relative movement. Proper performance of bearings is highly dependent on correct fits.
- However, an inner ring can creep or turn on its shaft seat if the seat is undersized or worn.
- This leads to increased noise and vibration levels as well as wear.
- Metalize and regrind the shaft seat to the appropriate size.
