Axial Deep Groove Ball B. SKF 51305
The SKF 51305 single-direction axial deep groove ball bearing supports shafts against axial loads in one direction; it is manufactured in the dimensions 25x52x18 mm.
The SKF 51305 axial deep groove ball bearing is a separable rolling bearing designed to accommodate axial forces acting in one direction. With a 25 mm bore, 52 mm outer diameter and 18 mm height, this model is suitable for precisely guided shafts. The construction consists of a shaft ring, a housing ring and the guided ball set with a sheet steel cage. Manufactured from standard roller bearing steel 100Cr6, the design is suitable for a temperature range of -30 to +150 degrees.
What is the 51305 axial deep-groove ball bearing suitable for?
This rolling bearing is designed to support purely axial forces acting on the shaft from a single direction. The bearing must not support radial loads; these require a separate radial bearing on the shaft. Typical applications can be found wherever axial forces are absorbed in a single direction. As the flat housing flange does not compensate for angular misalignment, the design requires precisely perpendicular contact surfaces on the shaft and housing.
What should be taken into account when aligning and installing bearing 51305?
The bearing is not angularly adjustable and is fitted without an additional shim. Manufacturing-related misalignments or shaft deflection cannot be compensated for with this design. Ensure that the bearing has a clean, flat seating surface in the housing. With a tolerance class of P0 or ABEC 1, the component meets standard mechanical engineering requirements. Before commissioning, the open bearing requires a suitable lubricant fill, tailored to your operating conditions.
What are the dimensions of the 51305 axial deep-groove ball bearing?
The bearing has an internal diameter of 25 mm, an external diameter of 52 mm and a height of 18 mm. The shaft washer has a ground bore for the shaft seat, whilst the housing washer has a larger internal diameter to allow the shaft to move freely.
In which direction does bearing 51305 absorb the load?
The bearing accommodates axial loads from one direction only. It supports the shaft axially in one direction. The design cannot transmit radial loads. If radial forces are also present in an application, the axial bearing is always used in combination with a suitable radial bearing.
Why does the 51305 axial deep-groove ball bearing not compensate for angular misalignment?
This model has a flat housing flange and is supplied without a spherical washer. Consequently, it lacks the geometric flexibility required for self-alignment. If misalignment occurs between the shaft and the housing axis, this results in uneven stresses on the rolling elements. The mounting surfaces must therefore always be machined so that they are exactly at right angles to the axis of rotation.
What is the permissible temperature range for the bearing?
The permissible operating temperature range is from -30 to +150 degrees. The standard 100Cr6 roller bearing steel used, as well as the sheet steel cage, retain their dimensional stability within this range. The actual operating temperature is always also determined by the lubricant selected, the operating limits of which must be matched to the ambient temperature.
What is the function of the sheet steel cage in the axial bearing?
The sheet steel cage guides the rolling elements along their raceway and prevents the balls from coming into contact with one another. This reduces friction and heat build-up during operation. At the same time, the cage holds the balls together, allowing the individual bearing discs and the ball ring set to be handled separately during assembly.
What is the tolerance class of the component?
The bearing is manufactured to tolerance class P0 (standard tolerance), which corresponds to ABEC 1. This classification specifies permissible deviations for dimensions, shape and axial runout. It covers the requirements of general mechanical engineering, provided that no higher precision in accordance with tighter tolerance classes is required.
