NJ 208 CT 40x80x18 cylindrical roller bearing

Main description

The NJ 208 CT cylindrical roller bearing with dimensions 40x80x18 mm is a durable rolling bearing designed for applications requiring high radial load capacity and reliable performance in industrial environments.

This model belongs to the NJ series of cylindrical roller bearings, widely used in mechanical systems where strength and operational stability are essential. Thanks to its design, the bearing can support not only heavy radial loads but also axial loads in one direction, making it more versatile than standard radial-only solutions.

The NJ 208 size range offers an excellent balance between compact dimensions and load carrying capability, making it suitable for medium to heavy duty applications across multiple industries.

Construction and design

The NJ 208 CT is a single row cylindrical roller bearing featuring flanges on the outer ring and one flange on the inner ring, which allows axial load support in one direction.

The cylindrical roller design provides line contact between rolling elements and raceways, significantly increasing radial load capacity compared to ball bearings. The internal cage ensures proper roller guidance, even load distribution and smooth operation under varying conditions.

The CT designation refers to a standard cage design, offering reliable performance and durability in typical industrial applications.
