Axial Deep Groove Ball B. SKF 52307
The SKF 52307 double-acting axial deep groove ball bearing accommodates axial forces in both directions and has dimensions of 30x68x44 mm.
The SKF 52307 axial deep-groove ball bearing is designed to support shafts that transmit axial forces in both directions. Manufactured from standard rolling bearing steel 100Cr6, this bearing consists of a shaft ring and two housing rings, complete with ball races. The integrated sheet steel cage guides the rolling elements over a temperature range of -30 to +150 °C. This rolling bearing serves as a solid basis for repairs and new designs where machine components subject to axial loads need to be supported.
What is the 52307 axial deep-groove ball bearing suitable for in operation?
This double-acting axial bearing is primarily suitable for designs in which purely axial loads occur alternately or in combination from two directions. By design, the bearing cannot accommodate radial forces; therefore, radial forces must be transferred via separate radial bearings. Typical applications include fixtures and assemblies subject to axial loads from both sides. As it is designed for temperatures ranging from -30 to +150 °C, the bearing operates within the specified limits even under thermal stress.
What should be taken into account when fitting the double-acting type 52307?
This bearing is a non-angle-adjustable version without shims. The contact surfaces in the housing and on the shaft must be exactly perpendicular to the axis of rotation, as misalignment leads to uneven load distribution and increased wear. Before installation, the mounting dimensions – with a 30 mm bore, 68 mm outer diameter and 44 mm overall width – must be checked. Manufacture to tolerance class P0 (ABEC 1) ensures dimensional accuracy in standard mechanical engineering.
What are the dimensions and tolerances of the 52307 axial deep-groove ball bearing?
The bearing has a bore diameter of 30 mm, an outside diameter of 68 mm and a depth of 44 mm. SKF manufactures this version to the standard tolerance P0 (corresponding to ABEC 1). This tolerance class meets the standard requirements in industrial mechanical engineering for precise fits on shafts and in bearing housings.
What does the term ‘double-acting’ mean in relation to this roller bearing?
Double-acting axial deep-groove ball bearings have two ball rings and three bearing rings. The centre ring is fixed to the shaft, whilst the two outer housing rings absorb axial thrust forces from opposite directions. This allows the shaft to be axially guided and supported on both sides without absorbing any radial loads.
Can the 52307 axial deep-groove ball bearing compensate for misalignment?
No, this version is not angle-adjustable and is supplied without spherical washers. The bearing components have flat contact surfaces. This means that misalignment between the shaft and the housing bore, as well as angular errors resulting from the manufacturing process, cannot be compensated for. It is therefore essential that the contact surfaces of the connecting structure are machined at right angles to the shaft axis.
What is the temperature range for which bearing 52307 is designed?
The bearing, made from 100Cr6 roller bearing steel with a sheet steel cage, is specified for operating temperatures between -30 and +150 °C. When designing the system, care must be taken to ensure that the lubricant is suitable for the applicable operating temperature in order to prevent the lubricating film from breaking down.
Can the 52307 axial deep-groove ball bearing also accommodate radial forces?
By their very nature, pure axial deep-groove ball bearings must not be subjected to any significant radial forces. If transverse or radial loads act on the bearing location, these must be fully transferred via separate radial bearings, such as cylindrical roller bearings or deep-groove ball bearings. The axial bearing is designed solely to accommodate thrust forces in the longitudinal direction of the shaft.
What is the purpose of the built-in sheet steel cage?
The stamped sheet steel cage maintains a uniform spacing between the rolling elements and reduces the weight of the rotating components. It offers good strength under mechanical stress and retains its shape throughout the entire temperature range from -30 to +150 °C. It also facilitates the supply of lubricant to the ball raceways.
