Axial Deep Groove Ball B. SKF 51109

The SKF 51109 axial deep-groove ball bearing supports axial forces in one direction and features compact dimensions of 45 × 65 × 14 mm.

This rolling bearing accommodates purely axial loads parallel to the axis and guides rotating machine components with precision. As a single-row, open component, the 51109 axial deep-groove ball bearing consists of a shaft ring, a housing ring and, between them, a ball and sheet steel cage. Manufactured from standard roller bearing steel (100Cr6), this design is suitable for operating temperatures ranging from –30 to +150 degrees. The components are designed to be separable, which facilitates installation on shafts and in bearing housings.

What is the 51109 axial deep-groove ball bearing suitable for?

It is used in general mechanical engineering applications where shafts are subjected to unilateral thrust loads. The 51109 axial deep groove ball bearing absorbs thrust forces but must not be subjected to radial loads. You should therefore combine this component within the system with separate radial bearings to ensure reliable guidance perpendicular to the shaft. Typical applications include shaft mountings with single-sided axial forces operating within the specified tolerance class P0/PN.

What is important to consider with the single-sided design?

The mating surfaces in the housing and on the shaft must be exactly perpendicular to the axis, as this design is not angle-adjustable. Misalignment leads to uneven load distribution across the rolling elements. The scope of supply comprises the axial bearing only, without a washer. The sheet steel cage facilitates lubricant exchange during operation. Ensure proper lubrication to guarantee correct operation within the temperature range up to +150 degrees.
