Round Flanged Linear Ball Bearing JPF (JIS)

Round Flanged Linear Ball Bearings

Round Flanged Ball Bearings have several advantages over Square Flanged bearings that experienced machinists would know. First, they don't have to be aligned as they rotate into position like one would have to do with a square flange. Second, they can fit into smaller spaces and are less likely to interfere with other components because they have no corners. Third, stress distribution is equal with a round flange. This is the standard single size version of the PBC Linear® flanged linear ball bearing line.
