Value Collection NCF20720E 4-bolt Flange Bearing 1-1/4 in Id

Product Description

The VALUE COLLECTION NCF20720E is a 4-bolt flange bearing unit designed to support rotating shafts in industrial and mechanical drive applications. With a 1-1/4 inch bore ID, it accepts standard shaft diameters commonly found in conveyor systems, agricultural equipment, HVAC blower assemblies, and general power transmission setups. The cast iron housing delivers rigid support and resists deformation under load, with a static load capacity of 3,461 pounds and a dynamic load capacity of 5,777 pounds. Overall dimensions measure 4-19/32 inches in length by 1-13/16 inches in height. This unit is installed by maintenance technicians and mechanical tradespeople working on rotating equipment.

This flange bearing is suited for light-to-medium industrial duty applications where a four-bolt mounting pattern provides secure, vibration-resistant attachment to a flat mounting surface. Typical installations include blower shafts, fan assemblies, pump drives, and conveyor line shafts in both commercial and light industrial environments. The 3-5/8 inch center-to-center spacing between mounting holes and the 3/4 inch base-to-center height allow for straightforward alignment during installation.

Compatibility

Designed as an OEM-style replacement or direct installation flange bearing for rotating shaft applications requiring a 1-1/4 inch bore, 4-bolt flange mount, and cast iron housing in standard industrial and mechanical drive systems.

Installation Notes

Installation should be performed by qualified maintenance or mechanical personnel. Ensure the shaft and mounting surface are clean and free of debris before seating the bearing. Torque all four mounting bolts evenly in a cross pattern to prevent misalignment. Shut down and lock out all power to the drive system before beginning installation or removal per OSHA lockout/tagout procedures.
