Caster bearing types
Bearings affect rolling resistance, speed, noise, maintenance and service life. Different wheel materials and load ranges use different bearings; formal models must be confirmed by specification and sample.
| Bearing types | Common features | Items to confirm |
|---|---|---|
| Ball bearing | Lower rolling resistance, suitable for higher speed requirements. | Model, sealing, dust protection, lubrication and load. |
| Needle bearing | Compact structure, commonly used in some industrial wheels. | Bore, sleeve, lubrication and operating speed. |
| Bushing structure | Simple structure; maintenance and cost depend on material. | Material, clearance, lubrication method and wear standard. |
| Special bearing | Used for heat resistance, water resistance, dust protection or special environments. | Environment, certification, service life and supply cycle. |
