Sintered Bronze Bushings, Standard Needle Roller Bearings, Ball Bearings

LP pulleys are available with a variety of sintered, oil-impregnated, bronze bushings and with ball and needle roller bearings. The following tables show the standard sizes. For specials, please contact the factory. With bearings, these pulleys offer excellent wear properties and prolonged life using loads not exceeding the recommended limits (click here to see note 3). Pulleys should not be allowed to move from side to side without restraints, because the bearing might work sideways out of the bore.
