Thrust ball bearings are rolling bearings engineered to handle axial loads exclusively. Their design features a shaft washer (tight ring), housing washer (loose ring), and a ball-cage assembly with grooved raceways, enabling efficient axial force transmission with minimal friction. Not suitable for radial loads.
Thrust Ball Bearing
| ISO | 51103 | |
| GOST | 8103 | |
| Bore diameter | d | 17 mm |
| Outside diameter | D | 30 mm |
| Height | H | 9 mm |
| Basic dynamic load rating | C | 2.3 kN |
| Basic static load rating | C0 | 3.1 kN |
| Reference speed | 5100 r/min | |
| Limiting speed | 3800 r/min | |
| Mass bearing | 0.025 kg | |
Structural Design
- Rings: GCr15 bearing steel hardened to HRC 58-62, precision-ground raceways;
- Balls: φ3mm-φ50mm steel balls (ISO 3290 Grade G10-G20);
- Cage: Stamped steel/brass or polymer PA66-GF25 segmented cage;
- Sealing: Z-shield (80°C) or 2RS rubber seal (120°C).
Key Performance Features
- By Sealing Type:
- Open Bearings: No seals; require regular lubrication.
- Shielded Bearings (ZZ/2Z): Single or double metal shields for dust protection (not oil-tight).
- Sealed Bearings (RS/2RS): Rubber seals for dust/water resistance and grease retention.
- By Size:
- Miniature Bearings: Bore diameter <10mm, used in precision instruments.
- Standard Bearings: Common sizes (e.g., 6200 series).
- Large-Size Bearings: For heavy-duty industrial equipment.
- Special Types:
- Stainless Steel Bearings: Corrosion-resistant for humid/chemical environments.
- Ceramic Hybrid Bearings: Ceramic balls for high-temperature and anti-magnetic applications.
Industrial Applications
| Industry | Equipment | Load Profile |
| Automotive | Clutch release, transmission | Shock loads ≤50kN |
| Construction | Hydraulic pumps, excavator slew | Static loads up to 300kN |
| Power Generation | Turbine guide vanes, wind pitch | Cyclic loads (50,000h life) |
| Robotics | Joint reducers | High-precision positioning |
Selection & Mounting Notes
- Corrosion Resistance: SUS440 stainless steel or zinc plating;
- Heavy-Duty Alternative: Use Tapered Roller Thrust Bearings(300% higher capacity);
- Mounting: Shaft washer MUST be press-fit; housing clearance ≤0.05mm.

Angular Contact Ball Bearings (ACBBs) are precision-engineered bearing units uniquely designed to handle combined radial and axial loads, simultaneously. Unlike standard deep groove ball bearings, they incorporate contact angles (typically between 15° to 40°), enabling them to support substantial axial forces in one direction, often alongside moderate radial forces. This…
