Browning 767440 Tapped Base Bearing 1 Inch Id Cast Iron

Product Description

The BROWNING 767440 is a tapped base pillow block bearing unit in the VTBS 200 series, designed for shaft support in light-to-medium duty rotating equipment applications. It carries a 1 inch bore with a straight bore profile and set screw locking mechanism, seating a 52100 bearing steel ball insert inside a cast iron housing. Static load capacity is 1,651 pounds and dynamic load capacity is 2,801 pounds, with a maximum rated speed of 5,500 RPM. The overall height is 2-13/16 inches and the overall length is 3 inches. Installation is typically performed by millwrights, maintenance technicians, or mechanical contractors working on conveyor systems, fans, pumps, and general power transmission equipment.

This tapped base bearing unit is suited for use in industrial and commercial mechanical assemblies where a low-profile, two-bolt mounting configuration is required. The tapped base design allows bolting from the underside, making it a common choice in applications with limited overhead access or where a flush top surface is needed. The VTBS 200 series is widely used in material handling, HVAC fan shaft assemblies, and light industrial drive systems. The 2 inch bolt hole center-to-center spacing and 1-7/16 inch base-to-center height suit standard mounting plate layouts commonly found in these applications.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. De-energize and lock out all power to the driven equipment before removing or installing any bearing unit. Ensure the mounting surface is clean, flat, and free of burrs before seating the housing. Tighten set screws to shaft per standard mechanical fastener practice and verify shaft alignment before returning equipment to service.
