Axial Deep Groove Ball B. FAG 51309
The FAG 51309 single-acting axial deep groove ball bearing accommodates pure axial forces and has dimensions of 45x85x28 mm.
The FAG 51309 axial deep groove ball bearing is a single-row, single-direction rolling bearing designed to support pure axial loads. With a bore of 45 mm, an outside diameter of 85 mm and a width of 28 mm, this rolling bearing supports shafts on one side. Manufactured from standard roller bearing steel 100Cr6 and fitted with a sheet steel cage, the component is suitable for a temperature range of -30 to +150 degrees. It is manufactured to tolerance class P0/PN (ABEC 1) to meet standard industrial requirements.
In which applications is the 51309 axial deep-groove ball bearing used?
This axial bearing is used where high axial forces act on rotating components in a defined direction. As the 51309 axial deep-groove ball bearing is not designed for radial forces, designers typically combine this component with separate radial bearings in practice. Typical applications can be found in general mechanical engineering in bearing arrangements subject to unilateral axial loading. As the bearing is not angularly adjustable, the design requires flat contact surfaces aligned precisely at right angles to the shaft axis in order to avoid edge loading on the rolling elements.
What is important when fitting the single-acting design?
This design comprises the axial deep-groove ball bearing without a washer and does not automatically compensate for misalignment. The flat housing washer requires a rigid housing bore with precise angular alignment. As the bearing can be dismantled, qualified personnel fit the shaft washer, housing washer and the steel sheet ball cage onto the 45 mm diameter shaft in sequence. To ensure proper function during operation, a sufficient minimum axial load is always required so that the balls roll within the guide cage rather than slide. Furthermore, the selected lubricant determines the usable operating range within the permissible temperature range of –30 to +150 degrees.
What are the dimensions of the 51309 axial deep-groove ball bearing?
With an internal diameter of 45 mm, an external diameter of 85 mm and a total width of 28 mm, this bearing is designed for 45 mm shafts. Thanks to its standardised main dimensions in accordance with tolerance class P0, the component can be integrated precisely into existing designs.
In which directions does bearing 51309 absorb loads?
The single-direction design accommodates only axial forces from a single direction and provides axial support for the shaft. This design cannot accommodate radial forces. For combined loads, an additional radial bearing on the shaft is therefore required.
What is the permissible temperature range for the 51309 axial deep-groove ball bearing?
Designed for operating temperatures ranging from -30 to +150 degrees, the bearing is made from 100Cr6 rolling bearing steel and features a sheet steel cage. In addition to the components, the lubricant used is also a key factor in determining the actual operating temperature; its temperature limits must be suited to the respective environment.
Can the 51339 axial deep-groove ball bearing compensate for angular misalignment?
No, this series is not angle-adjustable and is sensitive to misalignment between the shaft and the housing. A flat housing face without a shim requires all mating surfaces to be machined at right angles to the bearing axis. Only in this way are the axial forces distributed evenly across the entire circumference of the ball raceway.
What does tolerance class P0 mean for this rolling bearing?
The designation P0 (equivalent to PN or ABEC 1) defines the standard accuracy for dimensional and running error tolerances in accordance with international standards. Bearings in this tolerance class are suitable for industrial applications in mechanical engineering with standard requirements for concentricity and dimensional accuracy of the mating surfaces.
What material are the rolling elements and cage of bearing 51309 made of?
The bearing washers and the rolling elements are made from standard roller bearing steel (100Cr6), which has high compressive strength. A sheet steel cage guides the balls evenly along their path and ensures precise guidance of the rolling elements during rotational movement.
