Axial Deep Groove Ball B. SKF 52312

The SKF 52312 double-acting axial deep-groove ball bearing supports shafts with a 50 mm bore, an 110 mm outer diameter and a width of 64 mm in both axial directions.

The 52312 axial deep groove ball bearing is a rolling bearing made from standard bearing steel (100Cr6), specifically designed for pure axial loads. Manufactured to tolerance class P0/PN (corresponding to ABEC 1), it meets the permissible dimensional and running tolerances required for general mechanical engineering. Fitted with a sheet steel cage, the bearing is suitable for operating temperatures ranging from -30 to +150 degrees. The use of this open bearing is recommended where the shaft is axially fixed at both ends without radial support.

What is the 52312 axial deep-groove ball bearing suitable for?

This thrust bearing accommodates alternating or bidirectional axial loads and is used for fixed axial positioning. Typical applications include bearing arrangements in which axial compressive forces act on the shaft from both ends. As axial deep groove ball bearings, by their very design, must not absorb any radial forces, the assembly is always combined with suitable radial bearings. This ensures that the axial and radial load components are clearly separated from one another in the design.

What are the key features of the double-acting 52312 design?

As a double-acting variant, the bearing has two ball races and a central shaft ring between two housing plates. This design is not angle-adjustable. The mounting surfaces in the housing and on the shaft must be machined at right angles to the axis of rotation, as misalignment leads to uneven loading. The scope of supply comprises the axial bearing only, without shims. The lubricant must be selected to suit the operating temperature range of -30 to +150 degrees.
