52330M Solid Brass Window Cage, Bore 130 Mm, Axial Deep Groove Ball Bearings, Double Directions
The 52330M 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 52330M bearing is a Axial deep groove ball bearings, Double directions with an inner diameter of 130 mm , an outer diameter of 250 mm, a width of 140 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 413812 N, its static axial rated load is approximately 1337681 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
52330M bearings ( 130 mm x 250 mm x 140 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 52330M 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.
