These shields protect the bearing’s interior from larger contaminants without making contact with the inner ring, which allows for higher speed ratings compared to sealed (2RS) bearings.</p> <strong>Is this bearing suitable for high-temperature applications?</strong><br><p>Standard SKF 61803-2Z bearings with steel shields are filled with a standard grease and are suitable for operating temperatures up to 120 deg C (250 deg F). For higher temperatures, special grease and materials would be required.</p> <strong>What is the proper way to install a small bearing like this?</strong><br><p>For a small bearing, it is crucial to apply pressure only to the ring being press-fitted. For a shaft fit, press on the inner ring; for a housing fit, press on the outer ring. Never transmit the mounting force through the rolling elements, as this can damage the bearing.</p> <p>Last Update: Friday, March 13, 2026</p> <p><em>spareparts2day is not an authorized distributor, reseller or representative of the products featured on this website.
