Cel 81122TN is a specific type of thrust bearing. Here’s a breakdown of its key details:
1. Type of Bearing
- 81122TN is a thrust ball bearing. Thrust bearings are designed to handle axial (thrust) loads, which are forces parallel to the shaft’s axis. They are not suitable for radial loads.
2. Dimensiuni
- Cel 81122TN follows standard bearing dimension codes:
- 811: Indicates the series and type of thrust bearing.
- 22: Represents the bore diameter. For thrust bearings, the bore diameter is calculated as 22 x 5 = 110 milimetru.
- TN: Indicates the material of the bearing cage. TN stands for glass fiber-reinforced polyamide (nylon), which is lightweight and offers good performance in many applications.
3. Load Capacity
- Thrust ball bearings like the 81122TN are designed to handle high axial loads but are not suitable for high-speed applications or radial loads.
4. Aplicaţii
- Thrust bearings are commonly used in applications where axial loads are predominant, de exemplu:
- Automotive transmissions
- Cutii
- Machine tools
- Utilaje industriale
- Wind turbines
5. Maintenance
- Thrust bearings require proper lubrication to reduce friction and wear. Cel TN cage material is compatible with most lubricants, but always check the manufacturer’s recommendations.
6. Alternatives
- If the 81122TN is not available, you can look for bearings with similar dimensions and load ratings. Ensure the replacement matches the bore diameter, outer diameter, and width.
7. Manufacturer Variations
- Different manufacturers may have slight variations in design or materials, so always refer to the manufacturer’s datasheet for precise specifications.
