54228 Stamping Steel Cage, Bore 120 Mm, Axial Deep Groove Ball Bearings, Double Direction, With Spherical Housing Locating Washers
The 54228 Thrust ball bearings are widely used in various small and medium-sized equipment requiring axial load capacity, including: automotive steering systems, machine tool spindles, industrial gearboxes, crane hooks, centrifuges, and precision instruments.
The 54228 bearing is a Axial deep groove ball bearings, Double direction, With spherical housing locating washers with an inner diameter of 120 mm , an outer diameter of 200 mm, a width of 86.2 mm. It typically uses PN (ABEC-1) grade precision tolerances and GCr15, GCr15SiMn rings, GCr15, GCr15SiMn rolling mlement. Its dynamic axial rated load is approximately 188296 N, its static axial rated load is approximately 568324 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Interchange code: KOYO 54228, STEYR 54228, NACHI 54228, NSK 54228X,
54228 bearings ( 120 mm x 200 mm x 86.2 mm) have the advantages of Suitable for high-speed applications, capable of withstanding unidirectional axial loads, with low friction and easy installation, and are therefore widely used in the Machine tool spindles, automotive steering systems, pumps, industrial machinery and instruments.

The 54228 Thrust ball bearings mainly consist of a shaft ring (which mates with the shaft), a housing ring (which mates with the bearing housing), steel balls, and a cage. They feature a separable design for easy installation and maintenance. Some models include dust covers or sealed structures.
Thrust ball bearings have high axial load capacity, are suitable for bearing pure axial loads, have high limiting speeds, low friction coefficients, and smooth operation. Their separable structure simplifies installation, results in a compact size, and minimizes space requirements.
