Description
The N311ECMB/P6 SKF Cylindrical Roller Bearing from SKF is perfectly engineered to enhance the performance of your machinery. This bearing has an optimized internal design, a inner ring centred, machined brass cage, and a normal radial internal clearance, providing excellent durability, precision, and overall performance. The N-type design has no flanges on the outer ring and two flanges on the inner ring, meaning the outer ring is separable from the inner ring and roller and cage assembly. This allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions. The N311ECMB/P6 SKF bearing is purposely constructed to meet the demands of diverse industrial applications, ensuring optimal functionality in every setting. The dimensions of the SKF N311ECMB/P6 bearing are 55x120x29mm.

Key Features
Cylindrical Roller Design
The N311ECMB/P6 SKF bearing features a cylindrical roller design, optimising load distribution and facilitating high radial load capacity. N-type bearings are capable of accommodating axial displacement in both directions, making them ideal for demanding applications. A key attribute of these bearings is their separable outer ring, which simplifies the mounting process and allows for interchangeability of the bearing components.
High-Speed Capability
The N311ECMB/P6 SKF bearing is designed to handle high-speed operations while maintaining low noise and vibration levels. This ensures smooth and efficient rotation in dynamic environments without compromising stability. This makes it ideal for applications that demand rapid rotation.
Optimised Load Distribution and Carrying
The design of the N311 ECMB/P6 SKF bearing ensures even load distribution and carries heavy radial loads while maintaining a low cross-sectional height and low friction. This helps to enhance performance and ultimately extend the bearing’s lifespan.
Versatile Applications
The N311ECMB/P6 SKF bearing is suitable for a wide range of applications, including industrial machinery, power generation, and more. Whether you're in manufacturing, automotive, or any other industry requiring reliable rotational motion, the SKF N311ECMB/P6 is engineered to meet your requirements.
