SKF Thrust Roller Bearing 81105 TN, 25 mm ID, 42 mm OD, Reinforced Nylon Cage, 6300 rpm

SKF 81105 TN thrust roller bearing is engineered for demanding industrial applications requiring reliable axial load support and efficient high-speed operation.

With a 25 mm inside diameter and a 42 mm outside diameter, the 81105 TN model is designed for compact integration in rotary assemblies. Its 11 mm race width maximizes space efficiency, while the parallel bore type ensures precise fitting in mechanical and automation systems. The bearing's non-metallic cage also aids in dissipating heat, supporting extended service intervals and reducing maintenance requirements.

The 81105 TN is capable of handling static loads up to 69.5 kN and dynamic loads up to 25 kN, making it ideal for machinery subjected to heavy axial forces. Its fatigue limit load of 6.8 kN further enhances reliability, ensuring consistent operation in environments with continuous stress. The limiting speed of 6300 rpm enables use in high-speed applications, such as rotating assemblies within electronic devices and electrical engineering apparatus.

SKF's cylindrical roller thrust bearing is utilized in various mechanical systems, including commercial automation equipment, precision industrial tools, and applications demanding fast, accurate load distribution. Its construction supports a single row configuration, suitable for both direct and indirect load paths, and the reinforced nylon cage contributes to silent, smooth operation.

Practical use cases include automation, laboratory, electrical engineering, and commercial machinery. The bearing avoids excessive heat buildup and maintains operational efficiency at elevated speeds, supporting long-term industrial productivity. Installation and compatibility are straightforward, due to standardized bore and outer diameter measurements.

For those requiring precise axial load handling across electrical, electronic, and automation environments, the SKF 81105 TN thrust Roller Bearing meets critical performance standards. Engineers and maintenance professionals can depend on its proven static and dynamic ratings, reinforced cage material, and SKF’s reputation for quality bearings.
