LR604 belongs to LR series yoke-type track roller bearing (cam follower).

Single row deep groove ball internal structure with thickened outer ring, designed for outer ring rotating operation, rolling directly on guide rails or cam surfaces.

Common variants:

• LR604:Open type
• LR604ZZ:Double-sided metal dust shield
• LR604-2RS:Double contact rubber seal
• LR604U:R500 crowned outer surface, reduce edge stress and compensate minor misalignment

It mainly bears radial loads, suitable for compact, miniature automation equipment, medium-speed linear motion transmission. Pre-greased option available for maintenance-free operation.

Formal quotation will be sent within 24 hours upon your inquiry.
