Outer ring creeps (turns) in the housing seat

Worn or oversized seat

Considerations

• Most applications have a stationary housing where the load is unidirectional. This is considered a stationary outer ring load and, under most conditions, the outer ring can be held in place with a loose fit.
• However, an outer ring can creep or turn in its housing seat if the seat is oversized or worn.
• This leads to increased noise and vibration levels as well as wear.

Actions

• Metalize and regrind the housing seat to the appropriate size.
• For large housings, machining the seat to a larger diameter and using a cartridge sleeve might be a solution.

Unbalanced load

Considerations

• Loads resulting from an unbalanced shaft can cause outer ring creep, even if the fits are correct.

Actions

• Eliminate the source of the unbalance.
• Rebalance the machine.
