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:
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
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)
Application: Steering head, some wheel hubs
Features: Handles combined radial and axial loads, durable
Common models:
30203, 30205, 32005, 32006
Application: Gearboxes, crankshafts in some high-performance bikes
Features: High radial load capacity
Common models:
NU202, NJ203
Application: Front fork steering column, engine, clutch release mechanism
Features: Supports both radial and axial loads at high speeds
Common models:
7202, 7203, 7303
Application: Clutch release bearing, axial load zones in the gearbox
Features: Designed for axial load only
Common models:
51104, 51205
Application: Front and rear wheels
Features: Pre-lubricated, sealed, maintenance-free
Common models:
6202-2RS, 6302-2RS, DAC2552 (hub unit bearing)
Application: Rear shock absorber linkages, some steering components
Features: Allow misalignment and smooth articulation
