Axial Deep Groove Ball B. FAG 51228 -P5

The FAG 51228 -P5 axial deep-groove ball bearing reliably accommodates high unilateral axial forces whilst offering enhanced running accuracy, with dimensions of 140 × 200 × 46 mm.

The 51228 -P5 axial deep-groove ball bearing from FAG Rolling Bearings is designed as a single-direction bearing for supporting purely axial loads. With an inner diameter of 140 mm, an outer diameter of 200 mm and a height of 46 mm, this component precisely supports shafts in an axial direction. Its manufacture from standard rolling-bearing steel (100Cr6) and its design to the higher tolerance class P5 contribute to the precise guidance of rotating machine parts in continuous industrial operation.

What is the 51228 -P5 axial deep groove ball bearing suitable for?

This rolling bearing is used wherever heavy axial forces need to be absorbed in a defined direction and radial forces are supported separately. Typical applications include general gearbox and mechanical engineering, as well as vertical shaft mountings subject to purely axial loads. Thanks to its robust sheet steel cage and its operating temperature range of –30 to +150 degrees, the bearing operates reliably in both cold and thermally demanding industrial environments.

What are the advantages of tolerance class P5 when fitting bearings?

The P5 tolerance class specification, also known as ABEC 5, offers tighter manufacturing tolerances in terms of dimensional and running accuracy compared to the standard specification. This reduces unwanted axial runout of the shaft and housing discs and promotes smooth concentricity at higher rotational speeds. Please note during design that the 51228 -P5 bearing is not angularly adjustable. The mounting surfaces on the housing must be aligned at right angles to the shaft axis, as misalignment cannot be compensated for.
