1. Heavy - high centrifugal forces, not suitable for high speed.
2. Requires anti‑rust treatment (silver, zinc plating, or phosphating).
3. High machining precision required to avoid rolling element jamming.
4. Inspection: use borescope to check pocket edges - plastic deformation means increase hardness or enlarge fillet.
5. Maintenance: check rivets for looseness every 2000 hours.
