Sealmaster F-528 2-111C Flange Bearing Insert

Sealmaster F-508 2-111C insert, a two-bolt flange bearing insert with a 1-11/16 in bore, is designed to mount with a matching Sealmaster flange to support rotating shafts in light- to medium-duty equipment. The insert features a radial ball bearing assembly (bearing insert type: radial ball) set in an alloy-steel insert housed in a cast-iron flange, and it uses a double-seal closure to help keep lubricant in and contaminants out. Outer dimensions for the 2-111C family include an outer diameter of about 3.347 in and a width of about 1.938 in, supporting stable alignment in compact installations; it offers a basic dynamic rating of approximately 7,901 pounds and a maximum operational speed around 7,300 RPM, depending on mounting and load conditions. This combination makes it well-suited for applications such as conveyors, fans, and other machinery where a rugged, easily replaceable flange-mounted bearing insert is required.
