Product Description
Precision Flat Thrust Bearing 15x28x9mm 51102
51102 Flat Thrust Bearing 15×28×9mm provides reliable axial support for small to medium machinery. This single-direction thrust ball bearing is essential for mechanical transmission systems including machine tools, construction machinery, and automated equipment.
Basic Dimensions
| Inner Diameter (d) | 15mm |
|---|---|
| Outer Diameter (D) | 28mm |
| Thickness (T) | 9mm |
Structural Features
Features a separable design with three components: shaft washer, housing washer, and steel ball-cage assembly. This design simplifies installation and maintenance while allowing individual component replacement. Note: This bearing accommodates single-direction axial loads only and requires combination with radial support components.
Core Materials
- Bearing Rings: High-carbon chromium bearing steel (SAE-52100) with hardness HRC 60-64
- Rolling Elements: Precision-ground bearing steel balls with micron-level roundness control
- Cages: Nylon (PA66) for standard applications; stamped steel or brass for high-speed/high-temperature conditions
Performance Parameters
| Basic Dynamic Load Rating (C) | 10.5-10.6 kN |
|---|---|
| Basic Static Load Rating (C₀) | 16.8-18.3 kN |
| Limiting Speed (Grease) | 6200-6700 rpm |
| Limiting Speed (Oil) | 9400-10000 rpm |
| Temperature Range | -40℃ to 120℃ (extendable to 150℃ with special materials) |
Lubrication Requirements
Grease Lubrication: Recommended for speeds ≤6000 rpm. Use lithium-based grease (Grade EP2) filling 1/3-1/2 of bearing space.
Oil Lubrication: Recommended for high-speed (>6000 rpm) or high-load conditions. Use ISO VG32 or VG46 extreme pressure industrial gear oil.
Oil Lubrication: Recommended for high-speed (>6000 rpm) or high-load conditions. Use ISO VG32 or VG46 extreme pressure industrial gear oil.
Application Fields
- Small and medium-sized mechanical equipment
- Dental treatment chairs
- Barcode printers
- Small elevators
- Transmission systems
- Reducer output shafts
- Motor end cover axial support
- Roots pump rotor axial limits
- Light industry equipment
- Agricultural machinery
- Knitting machinery roller shafts
- Small tractor hydraulic systems
- Canning processing equipment
The 51102 flat thrust bearing combines precise dimensional design with separable construction, high-wear-resistance materials, and stable load-bearing performance, making it ideal for applications requiring high axial support accuracy and space efficiency.
