Heavy Duty Flange Block Bearing With Double Set Screw Locking For Secure Shaft Mounting 4 Bolt Piloted Flange Cast Iron Housing Heavy Contact Seal Rexnord MF5203 Fits 2 3 16 Inch Shaft 4 1 2 Inch Bolt Spacing 6 3 8 Inch Bolt Circle
✔️ Double set screws for secure shaft mounting; heavy-duty flange
This heavy-duty mounted spherical roller bearing sits in a 4-bolt square flange block housing and fits a 2-3/16 in shaft. The cast iron body delivers rigidity and vibration damping, with a powder-coated finish for corrosion resistance. It features two set-screw locking collars to secure the shaft, plus a spring-loaded, heavy contact seal to resist contaminants. The flange housing is 5 in square with a pilot extension for precise placement and stability during install. Maximum speed is 2,200 rpm, making it a solid choice for demanding industrial applications such as conveyors, mixers, and presses.
