Spherical Roller ‘Vibrating Screen’ bearings are the heavy-duty solution where impact and load are critical. The new generation of “Shaker Screen” bearings use hardened steel cages that are up to 10 times more impact-resistant than conventional cages. They also incorporate special O.D. tolerances as well as a special radial internal clearance range. Other advantages are that they are heat stabilized for 400F (200 C) continuous operation. The floating center guide ring and cage design allows for lower operating temperatures. Emerson Bearing features the new NACHI EXQ-V style as well as the FAG, NTN and NSK brands.
