Motorcycle Bearing 63/32-ZZ Double Shielded

62/63 Motorcycle Series Single Row Deep Groove Ball Bearings

They are characterized by having deep raceway grooves in which the inner and outer rings have circular arcs of slightly larger radius than that of the balls.

• Excellent for high speeds
• Good radial load capacity
• Acceptable axial load capacity in both directions
• Have low torque capacity at startup and running speeds
• Can operate with low noise
• Require little maintenance

These bearings have steel shields or rubber seals, installed on one or both sides and are pre-lubricated with grease. Also, snap rings are sometimes used on the outside edge. While many different retainers are available, pressed steel cages are most commonly used. Even tapered bores are available upon special order.
