Axial Deep Groove Ball B. FAG 51117
The 51117 axial deep-groove ball bearing, measuring 85 × 110 × 19 mm, withstands high unilateral axial forces and guides shafts accurately.
The 51117 axial deep-groove ball bearing supports rotating shafts in the axial direction and absorbs forces acting in one direction. The FAG rolling bearing design comprises a shaft ring, a housing ring and a set of balls guided within a sheet steel cage. Manufactured from standard rolling bearing steel (100Cr6), this bearing is characterised by its dimensional stability. The permissible temperature range extends from -30 to +150 degrees, enabling a wide range of applications in industrial environments.
What is the 51117 axial deep-groove ball bearing suitable for?
The 51117 axial deep-groove ball bearing is suitable for supporting purely axial loads and supports shafts in exactly one direction. As this design is single-acting, it must not be subjected to any radial forces. Typical applications include bearing arrangements where axial loads must be reliably supported. As the design is not angle-adjustable, installation requires precisely aligned and perpendicular contact surfaces.
What is important when installing a single-direction bearing?
The correct alignment of both discs is crucial for proper function. The shaft disc with the 85 mm bore sits firmly on the shaft, whilst the housing disc with an 110 mm outer diameter requires radial clearance within the housing. As this bearing is supplied without a shim, any installation inaccuracies cannot be compensated for. The tolerance class P0/PN or ABEC 1 is designed to ensure standard-compliant running characteristics for standardised design requirements in mechanical engineering.
What are the dimensions of the 51117 axial deep-groove ball bearing?
With a bore of 85 mm, an outer diameter of 110 mm and a height of 19 mm, the bearing complies with standardised specifications. It is suitable for shafts with a diameter of 85 mm where axial space is limited.
In which directions does the bearing absorb loads?
As a single-direction design, the bearing accommodates only axial forces from one direction. This type of bearing cannot support radial loads; therefore, where combined loads are present, additional radial bearings must be incorporated into the bearing arrangement.
What is the approved temperature range for the bearing?
The permissible operating temperature range is between -30 and +150 degrees. Thermal stability is based on the properties of 100Cr6 rolling-element bearing steel and the sheet steel cage. When selecting a lubricant, care must be taken to ensure that the chosen lubricant is suitable for the operating range.
What does the classification as tolerance class P0/PN or ABEC 1 mean?
In accordance with tolerance class P0/PN or ABEC 1, the standardised tolerances for dimensional and running accuracy apply. This classification covers typical operating conditions in general mechanical engineering, without the need for special accuracies for high-precision applications.
Can angular misalignment be compensated for using the 51117 axial deep-groove ball bearing?
No, the bearing is not angle-adjustable. It has flat disc surfaces and is fitted without a spherical washer. The mating surfaces on the shaft and housing must be aligned exactly at right angles to the axis to prevent the bearing from running on its edge and to avoid uneven loads.
What is the purpose of the sheet steel cage?
Acting as a cage, the sheet steel construction separates the rolling elements and maintains a uniform distance between them. This prevents direct contact between the balls, thereby reducing friction and heat build-up, and ensures stable guidance of the rolling elements during rotational movement.
