Applications


• Used in automation systems for efficient motion transfer
• Integral to mechanical assemblies for reduced friction
• Effective in electronic machinery requiring precise movement
• Applicable in heavy machinery for enhanced load management

What are the specific load ratings for this type of bearing?


The basic dynamic load rating is 38 kN, while the static load rating is 83 kN. This makes it suitable for applications that experience varying loads during operation.

How does the design contribute to its performance in industrial settings?


The needle roller design allows for a larger contact area, which increases load capacity and stability, making it ideal for high-stress environments.

What should be considered regarding installation tolerances?


Normal tolerances, along with P6 and P5 specifications, should be observed for optimal performance and to avoid premature wear in installations.

Are there specific seals compatible with this bearing model?


Yes, it is compatible with radial shaft seals that have low cross-sectional heights, both single lip and double lip variants.
