Axial Deep Groove Ball B. FAG 51406

The FAG 51406 axial deep-groove ball bearing, with dimensions of 30 × 70 × 28 mm, supports purely axial loads in one direction.

The 51406 axial deep-groove ball bearing is designed to specifically absorb axial forces in shaft bearings. With a bore of 30 mm, an outside diameter of 70 mm and a width of 28 mm, this design provides a standardised basis for axially loaded shafts. Manufactured from 100Cr6 rolling-bearing steel and fitted with a sheet steel cage, the design is rated for operating temperatures ranging from –30 to +150 degrees. With this FAG bearing, maintenance engineers and designers are provided with a precisely defined standard component.

What requirements is the 51406 axial deep-groove ball bearing designed to meet?

This rolling bearing absorbs high axial thrust forces acting unidirectionally along the axis of rotation. As the design operates as a single-acting bearing, it guides shafts precisely in one axial direction. The component must not bear radial loads, which is why the bearing arrangement must be combined with separate radial bearings. Due to the flat housing disc, installation requires absolutely perpendicular contact surfaces on the connecting structure to ensure even load distribution across the entire circumference of the ball crown.

What installation conditions apply to the 51406 axial deep-groove ball bearing?

When integrating this bearing from the 514 series, the alignment of the mounting surfaces plays a key role. The component is not angularly adjustable; therefore, it does not automatically compensate for misalignment or shaft deflection during operation. Furthermore, the scope of supply does not include shims. Precisely machined contact shoulders on the housing and shaft prevent impermissible edge pressures. In accordance with the standard tolerance P0 or ABEC 1, the manufacturing accuracy meets all standard requirements of industrial mechanical engineering.
