Bearings are the interface between the wheel and the axle — and the quality and type defines how freely your caster moves under load and how long it lasts.
Precision ball bearings use hardened steel balls in sealed raceways to minimize rolling friction and support consistent, low-resistance rotation.

Roller bearings use cylindrical rollers to spread load over a greater surface area. This increases load capacity and longevity under heavy use.

Standard ball bearings offer good balance between load capacity and rolling ease, and are often the go-to for general industrial caster wheels.

Plain bore bearings (also called sleeve or bushing bearings) have no rolling elements — instead they use a smooth bore to ride on the axle. They are cost-effective but have higher friction.

| Bearing Type | Rolling Resistance | Load Capacity | Maintenance | Best Use |
|---|---|---|---|---|
| Precision Ball | Very Low | High | Low | AGV, high-cycle, industrial |
| Roller | Low–Moderate | Very High | Moderate | Heavy-duty wheels |
| Ball (Standard) | Low | Moderate–High | Low | General industrial use |
| Plain Bore | High | Light–Moderate | Very Low | Light-duty carts |
Bearing selection is not just about friction — it also impacts:
Matching bearing type to your application can reduce maintenance costs and improve reliability.
