FAG 51111 single-direction axial deep-groove ball bearing with a 55 mm bore, 78 mm outside diameter and a guided sheet steel cage for purely axial loads.
The FAG 51111 axial deep groove ball bearing absorbs axial forces in one direction and supports the shaft axially against the housing. Manufactured from standard roller bearing steel (100Cr6) with standard tolerance P0/PN or ABEC 1, this bearing unit meets the requirements of conventional industrial applications in mechanical engineering. The separable design allows the shaft ring, housing ring and ball-cage assembly to be fitted independently of one another, which simplifies handling during installation.
This thrust bearing is primarily used where axial forces parallel to the axis need to be accommodated and no radial forces act on the bearing. As the bearing is designed to act on one side only, it accommodates loads exclusively in one direction. If additional radial forces occur in the bearing arrangement, the design requires the use of a separate radial bearing to protect the axial unit from excessive transverse forces.
The 51111 axial deep-groove ball bearing is not angularly adjustable and requires the connecting parts to be aligned. The contact surfaces on the shaft and bearing seat must be exactly perpendicular to the axis of rotation to prevent tilting or uneven loading of the ball rows. The bearing is fitted without a washer on flat housing surfaces. Within the specified temperature range of -30 to +150 degrees, the 100Cr6 components and the sheet steel cage retain their dimensional stability.
The bearing has a bore of 55 mm, an outside diameter of 78 mm and a height of 16 mm. These standardised dimensions allow for direct replacement in existing assemblies with corresponding mating surfaces on the shaft and bearing seat.
No, this thrust bearing is designed exclusively to withstand axial loads. If additional radial forces act on the bearing, these must be absorbed by separate radial bearings, such as deep-groove ball bearings or cylindrical roller bearings, in order to prevent damage to the raceways.
Single-acting designs consist of a shaft disc, a ball ring and a housing disc. They support axial loads in one direction only. In the case of alternating axial forces from two directions, however, a double-acting bearing or a mirror-image arrangement of two bearings would be required.
The permissible operating temperature range is from -30 to +150 degrees Celsius. The components made from standard roller bearing steel (100Cr6) and the guided sheet steel cage retain their dimensional stability within this range. The actual limit for continuous operation is determined by the lubricant selected.
No, this model is not angle-adjustable, as the housing disc has a flat contact surface. Any deflection of the shaft or misalignment of the contact surfaces will result in edge stresses. It is therefore essential that the contact surfaces in the housing are machined to a clean, flat finish.
The bearing is manufactured to tolerance class P0/PN (equivalent to ABEC 1). This is the conventional standard accuracy class in mechanical engineering, designed for standard operating requirements and standard fits on solid shafts and in one-piece housings.
