All About Single Row Bearing Idler Pulley

• Pressed steel pulleys are designed to make a complete, economical, self-contained unit for either the flat or "V" side of the 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 the 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.
• Our 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 an existing machine.
