Browning 766186 Pillow Block Bearing 1-7/16 Inch Bore

Product Description

The BROWNING 766186 is a VPB 200 Series pillow block bearing designed for industrial shaft support applications requiring a reliable, bolt-down bearing housing. It features a 1-7/16 inch straight bore with an eccentric lock collar for positive shaft retention. The cast iron housing pairs with a 52100 bearing steel insert ball bearing to handle demanding radial loads. Static load capacity is rated at 3,493 pounds and dynamic load capacity at 5,782 pounds, making it suited for moderate to heavy-duty rotating equipment. This bearing is typically installed by millwrights, maintenance mechanics, and industrial service technicians.

The BROWNING 766186 fits conveyor systems, fans, pumps, agricultural equipment, and general power transmission machinery where a standard two-bolt pillow block mounting is required. The 5 inch distance between mounting hole centers and an overall height of 3-11/16 inches accommodate common equipment frames and base plates. The base-to-center height of 1-7/8 inches allows for precise shaft alignment during installation. Maximum operating speed is rated at 4,000 RPM, making it appropriate for a wide range of rotational equipment in light industrial and agricultural settings.

Installation Notes

Installation is typically performed by millwrights or maintenance mechanics. Shut down and lock out all power to the driven equipment before removing or mounting any bearing housing. Align the shaft carefully to the base-to-center height specification before final bolt torque to prevent premature bearing wear. Consult applicable machinery safety standards and manufacturer guidelines for lubrication intervals and proper eccentric collar engagement procedures.
