Browning 766180 Pillow Block Bearing 1 Inch Id Cast Iron

Product Description

The BROWNING 766180 is a two-bolt pillow block bearing in the VPB 200 series, designed to support rotating shafts in industrial and commercial mechanical drive applications. The unit features a 1 inch straight bore and an eccentric lock collar for secure shaft engagement. The cast iron housing pairs with a 52100 bearing steel ball insert, combining durability with reliable radial load performance. Static load capacity is 1,651 pounds and dynamic load capacity is 2,801 pounds, making it suitable for moderate to heavy-duty conveyor, fan, pump, and general shaft-support installations. Licensed millwrights, maintenance mechanics, and industrial technicians are the typical installers.

The 766180 pillow block fits horizontal shaft mounting applications where a low-profile, bolt-down housing is required. The overall assembly measures 5.5 inches in length and 2.8125 inches in overall height, with the distance from the base to the shaft centerline at 1.4375 inches. Mounting hole centers are spaced 4.125 inches apart, accommodating standard two-bolt mounting patterns on equipment frames and support structures. Maximum rated shaft speed is 5,500 RPM. This unit is well suited for light conveyor lines, blower shafts, and agricultural or HVAC fan drive shafts in both indoor and sheltered outdoor environments.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic. Disengage and lock out all power to the drive system before mounting or removing the bearing assembly. Align the shaft carefully before tightening the eccentric lock collar to avoid inducing radial preload on the insert. Torque mounting bolts to the equipment manufacturer's specifications and verify shaft runout and alignment after installation.
