Carries combined radial and axial loads through a 17° contact angle, using ceramic balls in a M-series spindle bearing with bore 45.0 mm, outside diameter 75.0 mm and width 16.0 mm. Mass is 234.68 g, cage type T, no sealing arrangement. The design is a matched, adjusted set as indicated by the C designation, ready for mounting in pairs or sets without further selective fitting. The restricted tolerances of the P4S class combined with ceramic rolling elements give low mass and reduced centrifugal load on the balls, supporting stable running at elevated speeds. Without integrated sealing, the bearing requires external protection against contamination and a lubrication arrangement suited to the application, with the T cage material contributing to dimensional stability under thermal load. The XL designation reflects the specific technical execution of this variant as supplied by FAG.
