SKF 618112RZ Thin Section Deep Groove Ball Bearing with Two Low Friction Rubber Seals 55x72x9mm

RSL Range Deep Groove Ball Bearings: RSL series bearings have low friction acrylonitrile butadiene rubber steel reinforced seals fitted which form an extremely narrow gap between the seal and the cylindrical inner race surface. Being a practically non contacting they give the advantage of having a lower starting torque and rolling resistance in operation. Ideally suited to applications where ease of initial rotation is required they are equally at home in place of standard rubber sealed bearings and when fitted offer slight reductions in energy usage. They can be used at temperature from -40 to + 100 C or 120C for brief periods.
Benefits: Lower starting torques, lower rolling friction, rubber sealed
