Shurlok Rexnord Adapter Mounted Spherical Pillow Block Bearing With Locking Collar 2 Bolt Cast Iron Housing Non Expansion Heavy Duty Type 3 7/16 Inch Shaft 4 1/2 Inch Base To Center 12 3/8 Inch Bolt Centers Clearance Seal And Vibration Damping
✔️ 2-bolt cast iron housing, 3-7/16 in shaft, heavy duty design
Heavy-duty mounted spherical roller bearing with pillow block housing designed for rugged machinery. Cast iron construction provides rigidity and vibration damping, while powder coating resists corrosion. It uses a Shurlok adapter-mounted locking collar for secure shaft attachment and a clearance seal to resist contaminants. The unit is regreasable, expansion-type and operates up to 2,400 rpm. Optical strain sensors (OSS) and a positive locking system (PLS) give visual tightening confirmation. Overall height is 9-9/32" and base-to-centerline is 4-1/2" with bolt centers at 12-3/8", suitable for high-load, misalignment-tolerant applications.
