/ Thrust ball bearings

Single Thrust Ball Bearing

1.Product Introduction: It is also known as "Unidirectional Thrust Ball Bearings" in an informal abbreviation. It uses single-row steel balls to bear unidirectional axial loads and has a simple structure.
2.Structure Type: Shaft washer + housing washer + single-row steel balls + cage, open structure.
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, office equipment, light industrial machinery.
7.Key Inspection Items: Axial clearance, arrangement of steel balls, flatness of shaft washer and housing washer.

FAQ

1. How do your bearings survive 500°C in steel mills?

We use 20Cr2Ni4A alloy steel with vacuum heat treatment, reducing thermal expansion by 40%.

2. Can you make φ5000mm bearings for port cranes?

Yes! Our modular production system handles oversized orders without quality loss.

3. What ensures low noise in medical applications?

Precision-ground balls and P5-grade cages minimize vibration (tested per ISO 15242).

4. How fast can you ship to North America?

Standard bearings ship from Texas in 72 hours.
