Product description

The BH-7538-65 is a high-performance urethane spider insert for Rotary lift drive couplings. This part, which replaces Rotary OEM part P436-1 and S8547, is the flexible core of the coupling that connects the motor to the pump. Its primary job is to absorb shock loads and vibration while allowing for slight misalignment between shafts. Over time, the urethane material can become brittle or compressed, leading to increased noise and potential damage to the pump or motor bearings. SVI's replacement spider is made from premium high-density urethane, providing excellent damping properties and superior wear resistance. It is an essential, low-cost maintenance item that can prevent expensive power unit failures and ensure the smooth, quiet operation of your automotive lift.
