KOYO – Needle Roller Bearings covers drawn‑cup, caged and full‑complement needle bearings, track rollers and combined types. It details load ratings vs. envelope size, shaft/housing hardness and surface finish, as well as lubrication and sealing considerations to control wear and heat. Dimensional charts and tolerances enable fast interchange.
Content overview
- Drawn‑cup, caged, full‑complement and combined types.
- Track rollers and support rollers with seals.
- Tolerances, hardness and lubrication guidance.
- Interchange charts and envelope dimensions.
How to use
- Define load, envelope and support stiffness.
- Choose bearing type (drawn‑cup/caged/full‑complement).
- Check hardness/finish of mating surfaces and fits.
- Confirm lubrication path and sealing arrangement.
Best practices
- Ensure alignment of seats to avoid edge loading.
- Respect fillet radii; control chamfers and shoulders.
- Use double‑lip seals in abrasive environments.
- Set re‑grease intervals to the duty cycle.
