1. Introduktion
This manual provides essential information for the proper installation, operation, and maintenance of the uxcell S51102 Thrust Ball Bearing. Understanding these guidelines will ensure optimal performance and longevity of the bearing.
Thrust ball bearings are designed to accommodate axial loads and locate a shaft axially in one direction only. They are not intended for radial loads. The S51102 model features separable components, which simplifies both mounting and maintenance inspections.

2. Components and Material
The uxcell S51102 Thrust Ball Bearing consists of three main separable components:
- Shaft Washer: The inner ring, typically mounted on the shaft.
- Housing Washer: The outer ring, typically mounted in the housing.
- Ball and Cage Assembly: Contains the steel balls held in place by a cage, positioned between the two washers.
All components are constructed from 420 Stainless Steel. This material is a martensitic stainless steel known for its high and uniform hardness, good wear resistance, and corrosion resistance.

3. Installation og opsætning
The separable design of the uxcell S51102 thrust ball bearing simplifies its installation. Follow these steps for proper assembly:
- Forberedelse: Ensure all mating surfaces on the shaft and housing are clean, free from burrs, and properly machined to the correct tolerances.
- Smøring: Apply a suitable lubricant (e.g., grease) to the bearing components before assembly. This aids in initial operation and protects against corrosion.
- Shaft Washer Installation: Carefully slide the shaft washer (the inner ring with the smaller bore) onto the shaft.
- Ball and Cage Assembly Placement: Position the ball and cage assembly onto the shaft washer. Ensure it sits centrally.
- Housing Washer Installation: Place the housing washer (the outer ring with the larger outer diameter) on top of the ball and cage assembly, ensuring it aligns correctly with the housing.
- Final Seating: Gently press the components together to ensure they are fully seated. Avoid using excessive force or striking the bearing directly, as this can cause damage.
Proper alignment during installation is crucial for optimal performance and to prevent premature wear.

4. Operating Principles and Limitations
The uxcell S51102 Thrust Ball Bearing is specifically engineered to handle axial loads. It is designed to support a shaft axially in one direction.
- Axial Load Capacity: The bearing is designed to withstand forces acting parallel to the shaft axis.
- No Radial Load: It is critical that this bearing is ikke subjected to any radial loads (forces acting perpendicular to the shaft axis), as this will lead to rapid failure.
- Low-Speed Operation: This bearing is designed for low-speed applications. Refer to the specifications section for limiting speeds with grease and oil lubrication.
Typical applications include oven turntables, jacks, pumps, and various machine tools where axial support is required.
5. Vedligeholdelse
Regular maintenance is essential to ensure the long service life and reliable performance of your uxcell S51102 Thrust Ball Bearing.
- Renhed: Always maintain a clean working environment around the bearing. Contaminants such as dust, dirt, and debris can significantly reduce bearing life and cause premature wear.
- Smøring: Ensure the bearing is adequately lubricated at all times. Re-lubricate periodically with a compatible grease or oil, as specified for your application. Proper lubrication reduces friction, dissipates heat, and prevents corrosion.
- Inspektion: Periodically inspect the bearing for signs of wear, damage, or unusual noise during operation. Early detection of issues can prevent more significant problems.
- Opbevaring: If storing the bearing, keep it in its original packaging in a dry, clean environment to prevent corrosion and contamination.
