30x47x11 Flat Thrust Ball Bearing Precision Thrust Ball Bearing 51106 For Transmission Systems
The 51106 flat thrust bearing is a precision component designed for axial support in mechanical applications. With dimensions of 30mm inner diameter, 47mm outer diameter, and 11mm thickness, this bearing ensures stable and efficient operation across diverse machinery.
These precision dimensions ensure optimal fit with standard shafts while providing space-saving benefits for compact machinery designs.
The 51106 features a separable construction consisting of shaft washer, housing washer, and steel ball-cage assembly. This design simplifies installation and maintenance while providing unidirectional axial load support.
- Shaft washer rotates with the shaft (interference fit)
- Housing washer remains stationary (transition fit)
- Designed for axial loads only - requires radial support components
- Streamlined installation and disassembly processes
| Component | Material | Properties |
|---|---|---|
| Bearing Rings | SAE-52100 / GCr15 Steel | HRC 60-64 hardness, exceptional wear and fatigue resistance |
| Rolling Elements | Bearing Steel / Ceramic Options | Precision-ground surfaces, low friction, high-temperature resistance |
| Cages | Nylon PA66 / Steel / Brass | Lightweight, low friction, structural stability for various conditions |
Recommended for speeds ≤4000 r/min. Use lithium-based EP2 grease with 1/3 - 1/2 bearing space fill volume.
Preferred for high-speed (>4000 r/min) or high-load applications. Use ISO VG32 or VG46 gear oils via oil bath or injection methods.
- Small and Medium-Sized Machinery: Printing presses, medical examination tables
- Transmission Systems: Gearbox output shafts, positive-displacement pumps
- Light Industry and Agricultural Machinery: Textile knitting machines, tractor hydraulic systems
The 51106 flat thrust bearing provides reliable axial support with precise dimensions, high-quality materials, and excellent load-bearing performance. Ideal for applications requiring compact space utilization and high-precision axial support in small to medium-sized machinery.
