Types and Common Models of Motorcycle Bearings

Motorcycles rely on a range of bearings for various rotating parts such as the wheels, engine, transmission, crankshaft, steering system, and suspension. Below are the primary types and commonly used models:

 

1. Deep Groove Ball Bearings

• Application: Front and rear wheels, crankshaft, gearbox, starter motor, alternator

• Features: High speed, low friction, handles radial and light axial loads

• Common models:

  • 6000 series: 6000, 6001, 6002, 6003

  • 6200 series: 6201, 6202, 6203, 6204

  • 6300 series: 6302, 6303, 6304

 

2. Needle Roller Bearings

• Application: Connecting rods (piston pin ends), gearboxes, clutch mechanisms

• Features: Compact design, suitable for small spaces, high load capacity

• Common models:

  • HK0810, HK1012, HK1212, HK1816

  • K20x26x17, K22x26x13 (used in engines)

 

3. Tapered Roller Bearings

• Application: Steering head, some wheel hubs

• Features: Handles combined radial and axial loads, durable

• Common models:

  • 30203, 30205, 32005, 32006

 

4. Cylindrical Roller Bearings

• Application: Gearboxes, crankshafts in some high-performance bikes

• Features: High radial load capacity

• Common models:

  • NU202, NJ203

 

5. Angular Contact Ball Bearings

• Application: Front fork steering column, engine, clutch release mechanism

• Features: Supports both radial and axial loads at high speeds

• Common models:

  • 7202, 7203, 7303

 

6. Thrust Bearings

• Application: Clutch release bearing, axial load zones in the gearbox

• Features: Designed for axial load only

• Common models:

  • 51104, 51205

 

7. Specialized Wheel Bearings (Sealed Units)

• Application: Front and rear wheels

• Features: Pre-lubricated, sealed, maintenance-free

• Common models:

  • 6202-2RS, 6302-2RS, DAC2552 (hub unit bearing)

 

8. Rod End Bearings / Ball Joints

• Application: Rear shock absorber linkages, some steering components

• Features: Allow misalignment and smooth articulation
