Thrust bearings are mainly for axial load, while deep groove ball bearings are mainly for radial load and limited axial load. Selection should consider load direction, mounting structure and working conditions.
Thrust Bearing Supplier
F3-8M and 51101 support axial positioning and low-speed, light-load axial applications such as small mechanisms, rotating tables and equipment parts.
Product Overview
Thrust and flat bearings are mainly used for axial loads. Selection should focus on load direction, mounting space, washer structure, shaft washer and housing washer fit, and whether radial load is present. F3-8M is used for small axial positioning structures, while 51101 is a single-direction thrust ball bearing.
Specifications
| Model | Size | Material | Structure | Applications |
|---|---|---|---|---|
| F3-8M | 3x8x3mm; flange OD approx. 10mm, flange thickness approx. 0.6mm | GCr15 bearing steel; stainless steel can be customized | ZZ or open, to be specified | Small motors, models, printers, electric toys, medical devices |
| 51101 | 12x26x9mm | GCr15 bearing steel / stainless steel | Open; single-direction thrust structure | Machine tool screws, jacks, rotating tables, clutches |
Selection Notes
- Confirm the load direction. 51101 is for one-way axial load; use a radial bearing when radial load is the main requirement.
- Check shaft washer, housing washer and mounting surface fit before ordering.
- F3-8M is described here as standard GCr15 bearing steel, not as a stainless steel standard part.
- Specify ZZ or open structure when dust protection or rotation resistance matters.
FAQ
51101 is a single-direction thrust ball bearing for one-way axial load.
F3-8M is listed with standard GCr15 bearing steel scope; stainless steel versions can be discussed as a custom requirement.
