Description
This spindle bearing supports precise shaft positioning under a contact angle of 15°, with a bore diameter of 40.0 mm, outside diameter of 62.0 mm and width of 12.0 mm. It weighs 108.89 g and is fitted with a T cage. The bearing is supplied without sealing and is designed for adjusted mounting in pairs or sets, per the B719..-C design. The restricted tolerances (P4S) and the C contact angle variant make this bearing suitable for applications requiring high running accuracy and stable axial positioning under combined loading. Since it is unsealed, external sealing and lubrication arrangements must be provided by the housing design. Mounting in pairs or sets allows the axial internal clearance to be set according to the adjustment method used, which is essential for maintaining rigidity and rotational precision under the specified contact angle.
