• Designed with a bore type that is parallel for precise fit
• Single row configuration optimises space and load distribution
• Sealed end type extends service life by isolating lubricants
• High static load rating of 19900 N supports heavy loads
• Fatigue limit load of 3800 N enhances durability over time
• Dynamic load rating of 19500 N allows for smooth operation

• Used in automation systems requiring compact space
• Ideal for mechanical devices operating under high load conditions
• Suitable for electrical that demand precision
• Utilised in assemblies requiring high-performance steel roller bearings

The sealed design is critical as it prevents dust and debris from entering the bearing, thereby reducing wear and significantly extending its lifespan. This aspect is particularly vital in environments where contaminants could affect performance.

It has a high static load rating and a significant dynamic load rating, making it suitable for handling both static and dynamic forces effectively. Its robust construction allows for reliable operation under fluctuating loads, which is essential in many industrial applications.

While it is designed to be low maintenance due to its sealed nature, periodic inspection is recommended to ensure that there are no signs of wear or damage. If any issues are identified, replacement should be considered to maintain optimal performance.
