Axial Deep Groove Ball B. SKF 51116
The SKF 51116 axial deep groove ball bearing accurately accommodates unilateral axial forces with a bore of 80 mm, an outside diameter of 105 mm and a height of 19 mm.
The SKF 51116 axial deep groove ball bearing is designed as a single-acting rolling bearing for supporting purely axial loads. With an internal diameter of 80 mm, an external diameter of 105 mm and a width of 19 mm, the component supports shafts in an axial direction. Manufactured from standard rolling-element bearing steel (100Cr6) with a robust sheet steel cage, the component provides a solid foundation for industrial applications within a temperature range of –30 to +150 degrees Celsius. The dimensional accuracy complies with tolerance class P0/PN or ABEC 1.
What is the 51116 axial deep-groove ball bearing suitable for?
This rolling bearing is used wherever guidance tasks involving a purely axial load direction occur. Typical applications are found in mechanical engineering at bearing locations that are subjected exclusively to axial forces. As the component is designed to act on one side only, it absorbs thrust forces in an axial direction. The bearing must not absorb radial loads, which is why designs for transverse forces always incorporate separate radial bearings. As it is manufactured from 100Cr6, the axial bearing withstands typical compressive stresses and ensures smooth concentricity.
What is important when installing the non-angle-adjustable bearing 51116?
With the 51116 axial deep-groove ball bearing, the shaft and housing shoulders must be exactly perpendicular to the axis of rotation. This version is not angularly adjustable and is supplied without a shim, meaning that misalignment or shaft deflection cannot be compensated for. During assembly, care must be taken to ensure that the shaft washer is positioned precisely on the shaft, whilst the housing washer rests against the housing. For operation, a lubricant must also be selected that covers the operating temperature range from -30 to +150 degrees Celsius.
What are the dimensions of the 51116 axial deep-groove ball bearing?
The axial bearing has a bore of 80 mm, an outer diameter of 105 mm and an axial height of 19 mm. These standardised dimensions allow for direct replacement in existing assemblies. Before fitting, the mounting dimensions on the shaft and housing should be checked to ensure that the bearing shells sit flat.
What loads can the 51116 axial deep-groove ball bearing withstand?
As a single-direction bearing, this design accommodates only axial forces from one direction. By its very nature, this type of bearing cannot transmit radial forces. In machine designs, the bearing is therefore usually combined with separate radial bearings, which absorb the radial forces.
Can misalignment be compensated for using the 51116 axial deep-groove ball bearing?
No, the 51116 model is not angle-adjustable. The bearing has flat washers and is supplied without a spherical washer. The contact surfaces in the bearing housing and on the shaft must be manufactured to be plane-parallel and strictly perpendicular to the axis of rotation, as angular misalignment leads to uneven loading of the balls.
What is the permissible temperature range for the 51116 axial bearing?
The permissible operating temperature range is from -30 to +150 degrees Celsius. The bearing, made from standard roller bearing steel (100Cr6) with a sheet steel cage, is specified for these operating temperatures. The lubricant used must be suitable for the respective operating temperature, as lubricants determine the practical operating limit.
What does the tolerance class P0/PN or ABEC 1 mean?
This classification corresponds to the standard tolerances for dimensional and running accuracy in mechanical engineering. Bearings in this tolerance class offer defined dimensional stability for common industrial applications. They ensure reliable interchangeability and smooth running when standard requirements for concentricity and fit accuracy are met.
What is the purpose of the built-in sheet steel cage?
The sheet steel cage maintains a uniform spacing between the rolling elements. This prevents the balls from coming into direct contact with one another, reduces internal friction and ensures an even load distribution across the entire raceway. Furthermore, the material is designed to withstand temperatures of up to 150 degrees Celsius.
