Browning 767311 Pillow Block Bearing 1-1/4 Inch Id Cast Iron

Product Description

The BROWNING 767311 is a cast iron pillow block bearing designed for industrial and commercial power transmission applications. It accepts a 1-1/4 inch shaft bore and uses an eccentric locking collar to secure the bearing insert to the shaft without set screws cutting into the shaft surface. The unit measures 6-3/16 inches overall length and 3-5/32 inches overall height. Static load capacity is 2,567 pounds and dynamic load capacity is 4,381 pounds. The 52100 steel bearing insert provides hardness and wear resistance suitable for moderate-to-heavy radial load conditions. Mechanical technicians and millwrights install this unit in conveyor systems, agricultural equipment, fans, and general industrial machinery.

This pillow block is suited for shaft-mounted applications in industrial, agricultural, and light manufacturing environments. The two-bolt base configuration with 4-5/8 inch center-to-center mounting hole spacing fits standard pillow block mounting pads. The base-to-center height of 1-9/16 inches allows consistent shaft alignment across multiple bearing points on the same drive train. The eccentric lock collar design is commonly used in applications where frequent removal for maintenance is expected, reducing shaft damage during re-installation.

Key Features

• 1-1/4 inch inside diameter accommodates standard shaft sizes in industrial drive systems
• Eccentric locking collar secures insert to shaft without damaging shaft surface
• 52100 steel bearing insert for high hardness and extended service life under radial load
• Cast iron housing provides rigidity and vibration damping in mounted applications
• 2,567 pound static and 4,381 pound dynamic load capacities suitable for moderate-to-heavy duty use
• Two-bolt base with 4-5/8 inch mounting hole centers fits common mounting pad layouts

Compatibility

Designed as an OEM-style replacement pillow block bearing for two-bolt mounted shaft applications requiring a 1-1/4 inch bore with eccentric locking collar in cast iron housing.

Installation Notes

Installation is typically performed by a millwright or mechanical technician. Shut down and lock out all power to the drive system before removing or installing any bearing components, following LOTO procedures per OSHA 1910.147. Align the bearing housing squarely with the shaft and tighten the eccentric collar in the direction of shaft rotation to ensure proper lock engagement. Do not use impact tools on the locking collar or housing during installation.
