  • Design considerations SKF SKF

    In most rolling mill applications, four-row tapered roller bearings are mounted with a loose fit on the roll neck. This enables quick roll changes. However, loose fits have the disadvantage that the inner rings turn on their seats under load. To reduce the effects of a loose fit, SKF bearings have a helical groove in the bore and/or lubricationBearing Service Company IRD Rolling Mill Bearings,•Avoid removing bearings by pulling on the rollers or cage. •Cylindrical roller bearings in rolling mills typically have a radial internal clearance between 0.010 to 0.030” and accept little to no misalignment. •Roll chock alignment is critical during installation. •Identified By: •Nicks
