Free Spinning ER Insert Bearings
CBB also offers a free spinning ER insert bearing option, designed to excel in critical applications like pulp and paper converting, printing, and packaging. Precise raceway curvatures combined with superb surface finishes help provide a low coefficient of friction. To further reduce the rotational torque or drag, these bearings are lubricated with a low viscosity oil, or light consistency grease and have low drag/non contact seals.
Free Spinning bearings utilize a formed metal slinger in conjunction with a modified Buna-Nitrile seal forming an effective labyrinth design. Although there are two seals involved, there is actually no contact of the sealing elements with the rotating bearing components. Yet the unique design does an excellent job of keeping out contamination, while yielding the lowest possible torque.
Free spinning ER type bearings are great for packaging equipment, printing machinery, in-line systems and conveyor equipment!
