Application Info

This is a common bearing for a 2-1/2 OD roller, fit into an adapter that allows it to be installed in a 3-1/2 OD x 7 ga. roller with relatively light loads. Recommended for slow powered applications and gravity conveyor applications. The lack of seals or shields reduces drag but offers no protection against dirt and debris. Not recommended for dirty or dusty environments. Not recommended for high speeds or CDLR.
