Self-Aligning Ball B. SKF 1315 K

The SKF 1315 K self-aligning ball bearing, measuring 75x160x37 mm and featuring a tapered bore, offers a robust solution for shaft mountings that can accommodate misalignment.

The SKF 1315 K double-row self-aligning ball bearing features two rows of balls on a common hollow-spherical outer ring raceway. Thanks to this geometric design, the bearing automatically compensates for both static and dynamic angular misalignment between the inner and outer rings. As an open rolling bearing made from standard rolling bearing steel (100Cr6) with a sheet steel cage, the unit is designed for operating temperatures ranging from –30 to +150 degrees. It is suitable for demanding applications in industrial machinery and plant engineering.

When does the 1315 K self-aligning ball bearing compensate for misalignment?

This design is primarily used on long shafts that are prone to deflection under load or where manufacturing-related misalignments occur between the bearing seats. The spherical raceway in the outer ring allows the balls to move freely, thereby preventing additional friction caused by misalignment. It is primarily used in shaft lines and bearing arrangements where combined radial loads and moderate axial forces must be reliably supported.

What assembly advantages does the 1:12 tapered bore offer?

The suffix ‘K’ denotes the tapered inner ring bore with a standard taper of 1:12. This design facilitates mounting on stepped shafts or cylindrical shaft journals in conjunction with clamping or withdrawal sleeves. By sliding the bearing axially onto the tapered seat, the standard radial bearing clearance can be precisely adjusted during installation. As an open rolling bearing, lubrication with grease or oil can be selected to suit the operating conditions.
