Axial Deep Groove Ball B. SKF 51306

The SKF 51306 axial deep-groove ball bearing reliably absorbs unidirectional axial forces in mechanical engineering applications, with main dimensions of 30x60x21 mm.

This SKF 51306 axial deep-groove ball bearing supports axial forces in one direction and guides shafts with precision. With a bore of 30 mm, an outside diameter of 60 mm and a width of 21 mm, this component is suitable for compact designs. Manufactured from standard rolling-element bearing steel (100Cr6) with a guided sheet steel cage, this version is designed for operating temperatures ranging from -30 to +150 degrees. The scope of supply includes only the axial deep-groove ball bearing, without a washer or any additional inserts.

What are the applications of the single-acting axial deep groove ball bearing 51306?

Designs utilise this type of bearing when pure thrust forces along the shaft axis need to be absorbed. The bearing supports components in an axial direction and maintains the axial positioning of the shaft. Due to its design, this type of rolling bearing is not suitable for withstanding radial loads. If radial forces are also present, the bearing arrangement requires a separate radial bearing. The separable design, comprising a shaft washer, housing washer and ball-cage assembly, also facilitates the separate installation of the individual bearing rings.

What is important to bear in mind when fitting bearings without angular adjustment?

As the 51306 axial deep-groove ball bearing is not angle-adjustable, the contact surfaces in the housing and on the shaft must be plane-parallel to one another and exactly perpendicular to the axis of rotation. Misalignment leads to uneven loading of the rolling elements and reduces service life. The design complies with the standard tolerance class P0/PN or ABEC 1, which ensures defined dimensional accuracy for standardised bearing seats.
