/ Thrust ball bearings

Single Direction Thrust Ball Bearing

1.Product Introduction: The same as "Single-row Thrust Ball Bearings". It uses single-row steel balls to bear unidirectional axial loads and is suitable for light and medium unidirectional load scenarios.
2.Structure Type: Shaft washer + housing washer + single-row steel balls + cage. The shaft washer is tightly fitted to the shaft, and the housing washer is tightly fitted to the bearing housing.
3.Size Range: Inner diameter: 10 - 300mm, outer diameter: 30 - 400mm, height: 8 - 50mm.
4.Material: Shaft washer: GCr15/GCR15SIMN/20Cr2Ni4A, housing washer: GCr15/GCR15SIMN/20Cr2Ni4A, rolling elements (steel balls): GCr15/GCR15SIMN, cage: stamped steel / brass.
5.Accuracy: Conventional P0/P6 grades, precision models are of P5 grade.
6.Application Fields: Water pumps, small motors, feed shafts of machine tools, light industrial equipment.
7.Key Inspection Items: Axial clearance, conformity of steel balls fitting, flatness of shaft washer.
