Round Flange Block With Relubricatable Non Expansion Cast Iron Housing And Four Bolt Holes For Heavy Duty Bearings Rexnord ZBR2308 Three And One Half Inch Bore Diameter Setscrew Locking Collar

Heavy-Duty Round Flange Block with Relubricable Cast Iron
✔️ 3.5 in bore, four bolt holes, setscrew collar, relubricable

Round flange block with four bolt holes is a heavy duty mounting housing designed for perpendicular shaft mounting. The non expansion cast iron housing provides rigidity and vibration damping, and a pilot extension ensures precise placement on the mounting surface. The double sealed spherical roller bearing insert handles heavy radial or mixed radial and axial loads, and a grease fitting on the housing allows easy relubrication. The setscrew locking collar uses a three-point contact at 120 degrees to minimize shaft distortion and vibration. Powder coating enhances corrosion resistance for industrial use.
