Product Description
Urethane Bearing Block Backing Plates w/Triple Lip Nitrile Seals
These backing plates are made from structural urethane and are uniquely designed to fit select styles of Timken round piloted bearing block units
Please note the HSY backing plates only fit QMC/QMCW/QAC/QACW round piloted flange blocks that use either concentric or eccentric bearing shaft collars (Not available for tapered adapter or V-Lock® bearing units)
