This design allows for easy mounting and dismounting using an adapter sleeve or withdrawal sleeve on a cylindrical shaft.</p> <strong>What is the significance of the C3 clearance?</strong><br><p>C3 is an internal radial clearance that is greater than the ‘Normal’ clearance. It is used in applications where there may be a tight fit on the shaft or in the housing, or where a temperature differential between the inner and outer rings could reduce operational clearance.</p> <strong>What are the lubrication requirements for the S11 variant?</strong><br><p>The S11 suffix means the bearing rings are heat-stabilized for operation at temperatures up to 200 deg Celsius. It is critical to use a compatible high-temperature grease to ensure proper lubrication and achieve the expected service life in such conditions.</p> <p><em>profideals is not an authorized distributor, reseller or representative of the products featured on this website.
