Axial Deep Groove Ball B. SKF 51105
The 51105 single-direction axial deep groove ball bearing is designed for shafts measuring 25x42x11 mm and is intended for purely axial loads from a single direction.
The SKF 51105 axial deep groove ball bearing is a separable rolling bearing designed to accommodate purely axial forces. Fitted with a shaft ring, a housing ring, and a guided ball and sheet steel cage, this component supports shafts in a defined axial direction. The bearing is made of standard rolling-element bearing steel (100Cr6) and operates within a temperature range of -30 to +150 °C. As the individual elements can be separated, you can mount the components separately onto the shaft and into the surrounding housing, saving time.
What is the 51105 axial deep-groove ball bearing suitable for?
This rolling bearing is suitable for designs in which high axial loads occur and radial forces are either excluded or absorbed by separate radial bearings. As the component acts on one side only, it absorbs axial thrust forces exclusively from one direction. Typical applications include bearing arrangements subject to axial thrust loads in general mechanical engineering. The design complies with standard tolerance P0/PN or ABEC 1 and ensures smooth guidance of rotating machine parts within the defined operating range.
What installation requirements does the rigid version of bearing 51105 have?
The component is not angle-adjustable and is supplied without an additional shim, which is why the contact surfaces on the housing and shaft must be exactly perpendicular to the axis of rotation. Due to its design, this axial bearing does not compensate for misalignment or shaft deflection. Misalignment leads to edge stresses, which increase wear on the raceways. During installation, ensure that the shaft and housing washers are correctly aligned and that suitable lubrication is provided to maintain operational reliability within the temperature range of -30 to +150 °C.
What are the dimensions of the 51105 axial deep-groove ball bearing?
The bore measures 25 mm and accommodates the shaft with a precise fit. The outer diameter is 42 mm, with a total width of 11 mm. These compact dimensions allow for installation in space-constrained housing designs. Thanks to the modular design, the shaft washer, ball cage and housing washer can be measured and fitted individually.
In which directions does bearing 51105 absorb loads?
This axial deep-groove ball bearing is designed to act on one side only and absorbs axial forces from one direction only. It supports the shaft in the axial direction but must not be subjected to radial loads. If combined radial and axial forces occur in an application, combine this component with a separate radial bearing.
What material is the 51105 axial deep-groove ball bearing made of?
Both the shaft and housing washers and the rolling elements are made from standard roller bearing steel (100Cr6). This through-hardened material offers high dimensional stability under load. The balls are guided by a sheet steel cage, which keeps the rolling elements at a uniform distance and is designed for operating temperatures ranging from -30 to +150 °C.
Can the thrust bearing compensate for misalignment?
No, the 51105 design is not angle-adjustable. It has a flat housing washer and is fitted without a spherical washer. The mating surfaces in the housing and on the shaft must be machined to be exactly plane-parallel and at right angles to one another, as misalignment leads to localised overloads on the rolling elements and raceways.
What is the tolerance class of this thrust bearing?
The bearing complies with tolerance class P0 or PN, which corresponds to the ABEC 1 standard. This standard tolerance meets the usual requirements in general industrial and mechanical engineering with regard to dimensional, geometric and running accuracy. From a design perspective, this ensures reliable interchangeability during maintenance work without the need for time-consuming reworking of the mounting dimensions.
What is the permissible operating temperature range?
The metal bearing components made from 100Cr6 rolling-element bearing steel and the sheet steel cage are suitable for a temperature range of -30 to +150 °C. To ensure trouble-free operation, the lubricant used must be suitable for the same temperature range, as the viscosity of the lubricant has a significant influence on friction and heat generation.
