Axial Deep Groove Ball B. SKF 51114

The SKF 51114 axial deep-groove ball bearing accommodates unilateral axial forces for shaft diameters of 70 mm in mechanical and plant engineering.

The 51114 axial deep-groove ball bearing is designed as a separable rolling bearing for the specific purpose of accommodating purely axial forces. With key dimensions of a 70 mm bore, 95 mm outside diameter and 18 mm height, this design supports shafts on one side. SKF manufactures the components from standard 100Cr6 rolling-bearing steel to the standard tolerance P0 or PN. A dimensionally stable sheet steel cage guides the rolling elements evenly along their raceways.

What loads can the 51114 axial deep-groove ball bearing withstand?

The 51114 axial deep-groove ball bearing is designed to transmit considerable axial forces acting parallel to the axis of rotation. In technical bearing arrangements, the single-acting design supports defined longitudinal forces in one direction. As this component accommodates only single-sided axial loads, no radial loads whatsoever must act on the bearing discs. Any radial forces must be absorbed by separate radial bearings on the same shaft to prevent impermissible stress on the raceways. The fact that the shaft and housing rings can be separated facilitates the separate installation of both bearing rings.

What is important when fitting a single-acting bearing?

During assembly, care must be taken to ensure that the connecting parts are precisely perpendicular to the shaft axis, as this design is not angle-adjustable. Planar, parallel contact surfaces prevent localised edge stresses on the raceways of the rings. The scope of supply includes the axial deep-groove ball bearing without separate shims. Together with the sheet steel cage and the 100Cr6 rolling bearing steel, the bearing is designed for operating temperatures ranging from -30 to +150 degrees Celsius.
