Flat Non Flanged Idler Pulley - Single Row Bearing

  • Pressed steel pulleys are designed to make a complete, economical, self contained unit for either flat or "V" side of belt.
  • They are furnished with a single-row, radial-type, highest quality precision ground, pre-lubricated ball bearing (made of 52100 bearing steel) with contact-type seals to insure positive retention of lubricant and full protection against dirt, dust or foreign matter.
  • These bearings contain a 60% fill of high temperature grease, no re-lubrication required.
  • The ball bearing inner ring is extended on both sides to provide clearance for abutting parts and greater support on the shaft.
  • A compression ring (USA Patent No. 4518372) is compressed between the center O.D. of bearing and center I.D. of pulley bearing pocket to assure a firm reliable fit of pulleys to bearing.
  • This helps distribute loads from the pulley more evenly to the outer bearing race resulting in minimum distortion of bearing O.D.
  • Tests have proven this method of bearing installation to give longer and more reliable bearing life.
  • With little or no alterations, these belt pulleys can be adapted to new designs or to existing machine.
