Square flange type JIS standard cast iron housing ball high temperature bearing units with set screw locking

This square flanged ball bearing unit is designed to withstand high temperature applications in accordance with ISO standards. Includes high temperature recessed bearing with extended inner ring and setscrew locking mechanism for applications with fixed or alternating direction of rotation. The bearings are mounted in cast iron housings and can be bolted to machine sidewalls or frames. The ball bearing units are capable of withstanding moderate initial misalignment, but axial displacement is not normally permitted.

  • Can withstand high contamination
  • Designed for high temperature, high speed equipment applications
  • Can withstand heavier loads
  • Good price/performance ratio
