51114 Stamping Steel Cage, Bore 70 Mm, Axial Deep Groove Ball Bearings, Single Direction
The 51114 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 51114 bearing is a Axial deep groove ball bearings, Single direction with an inner diameter of 70 mm , an outer diameter of 95 mm, a width of 18 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 39773 N, its static axial rated load is approximately 109793 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Interchange code: NSK 51114, NTN 51114, FAG 51114, SKF 51114, STEYR 51114, KOYO 51114, NACHI 51114, SNR 51114, RHP 51114,
51114 bearings ( 70 mm x 95 mm x 18 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 51114 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.
