Axial Deep Groove Ball B. SKF 51312
The SKF 51312 axial deep groove ball bearing accommodates unilateral axial forces, is made from standard rolling bearing steel (100Cr6) and measures 60x110x35 mm.
The SKF 51312 axial deep groove ball bearing is designed for applications where purely axial forces in one direction need to be supported. This design must not be used to support radial forces. Manufactured from standard roller bearing steel 100Cr6 and fitted with a sheet steel cage, this version is suitable for axial guidance in mechanical engineering. The bearing covers a temperature range from -30 to +150 degrees and operates with the standard tolerance P0/PN (ABEC 1).
In which installation scenarios does the 51312 axial deep-groove ball bearing prove its worth?
This rolling bearing supports rotating shafts against axial loads acting from one side. Typical applications include vertically guided shafts or shaft trains subject to mechanical axial thrust. As the 513 series comprises non-angle-adjustable bearings, the shaft and housing axes must not be misaligned. A rigid, precisely perpendicular bearing environment ensures even load distribution across the rolling elements.
What is important when installing a single-direction bearing?
The bearing’s flat housing flange is fitted without an additional shim, which requires a flat, perpendicular mating surface. Before fitting, the 60 mm bore and the 110 mm outer diameter must be checked against the specified seating surfaces. As the bearing is not sealed, structural seals protect the open raceways from contamination, supplemented by lubricants suitable for temperatures ranging from -30 to +150 degrees.
What are the key features of the 51312 axial deep-groove ball bearing?
This SKF split, single-direction axial bearing comprises a shaft ring, a housing ring and a set of balls in a sheet steel cage. The design is intended to accommodate axial loads from one direction only and must not be subjected to radial forces.
What are the dimensions of the 51312 axial deep-groove ball bearing?
With an internal diameter (bore) of 60 mm, an external diameter of 110 mm and a total width of 35 mm, the bearing complies with the standardised 513 series for axial loads whilst maintaining a compact overall height. These dimensions determine the appropriate design of the corresponding shaft and housing shoulders.
Can the bearing compensate for angular misalignment between the shaft and the housing?
No, the 51312 axial deep-groove ball bearing is not angle-adjustable. The flat housing washer requires a contact surface that is perpendicular to the axis of rotation. If misalignment or skew occurs, this leads to one-sided overloading of the raceways. Angular-compensating variants, on the other hand, require spherical housing washers with suitable shims.
What is the temperature range for which this bearing is designed?
The bearing is designed for operating temperatures ranging from -30 to +150 degrees. The sheet steel cage and the 100Cr6 rolling bearing steel cover this range. When selecting the lubricant, it is advisable to ensure that the grease or lubricating oil retains its lubricating effect within this temperature range.
What is the purpose of the sheet steel cage in the warehouse?
The sheet steel cage guides the rolling elements at a uniform distance around the circumference of the raceway. It prevents direct contact between adjacent balls, thereby reducing friction and heat build-up. Sheet steel offers a low weight whilst ensuring dimensionally stable guidance during normal operation.
What does tolerance class P0 or ABEC 1 mean?
Classification according to tolerance class P0 (DIN/ISO) corresponds to class ABEC 1 and describes the standard tolerance for dimensional and running accuracy. This accuracy class meets the requirements of general mechanical engineering, plant engineering and gearbox manufacturing, provided there are no specific precision requirements regarding concentricity or noise levels.
