NJ2308ECP/C4 SKF Cylindrical Roller Bearing 40x90x33mmThe rollers in a single row cylindrical roller bearing are always guided between the integral 'open' flanges on one of the rings. These 'open' flanges combined with the specially designed and surface finished roller ends, provide improved lubrication, reduced friction and consequently lower operating temperature. The ring with the integral flanges together with the cylindrical roller and cage assembly can be separated from the other ring. This results in easy mounting and dismounting, particularly where the load conditions are such that interference fits are required for both rings. Single row cylindrical roller bearings can accommodate heavy radial loads and high speeds.

What are Single Row Cylindrical Roller Bearings?

Single Row Cylindrical Roller Bearings are a type of roller bearing using cylindrical rollers as the rolling elements. These bearings are designed for high radial loads, due to the large contact area between the rollers and raceways, making them ideal for high-speed applications. The single row design consists of an inner and outer ring with a single row of cylindrical rollers in between, and they are primarily designed to support radial loads, offering limited or no ability to handle axial loads.



Key Features:


High Radial Load Capacity: The cylindrical rollers provide a large contact surface, making these bearings well-suited for high radial loads.

Low Friction Operation: Optimized for minimal friction, allowing high-speed operation with efficient heat dissipation.

Axial Movement Flexibility: Some types allow limited axial displacement of the inner or outer ring, preventing stress from thermal expansion in fixed shafts.

Separable Design: The separable inner or outer ring allows for easier assembly and disassembly, as well as simplified maintenance.

Precision Designs: Available in varied internal clearances and precision levels to meet specific application requirements.




Types:


NU Type: Allows axial displacement in both directions, suitable for applications with shaft expansion.

N Type: Supports axial movement within the bearing, ideal for unrestricted shaft movement.

NJ Type: Can carry limited axial loads in one direction.

NUP Type: Supports fixed axial load in both directions.

NF Type: Provides axial load support in one direction, making it suitable for applications with moderate axial load requirements.

NC Type: Designed with a retaining ring that provides limited axial positioning, allowing for fixed axial movement in one direction.

SL Type: Full-complement cylindrical roller bearing with no cage, offering a high load capacity for applications with slower rotational speeds.

BC1 Type: Specialized for high-speed applications, with an enhanced inner ring for additional support in high-stress environments.




Benefits:


Durability: Cylindrical rollers and raceways have increased contact surfaces, enhancing durability and load-carrying capability.

High-Speed Capability: Low friction and minimal heat generation allow for smooth operation at high speeds.

Easy Installation: Separable rings make installation and maintenance more convenient.

Extended Equipment Lifespan: Efficient load distribution and low operating temperature reduce wear on machinery components.




Applications:

Gearboxes and Transmissions: Used in automotive, industrial, and heavy machinery gear systems due to high load and speed requirements.

Electric Motors and Generators: Suitable for high-speed electric motors where radial load support is essential.

Pumps and Compressors: Provide reliable support for rotating components in high-stress environments.

Construction and Mining Equipment: Used in large machinery that requires durable, high-load bearings.




Single Row Cylindrical Roller Bearings are robust and efficient for high radial load applications, especially where high-speed performance and minimal maintenance are priorities. Their versatile types, efficient load handling, and separable design make them a preferred choice for demanding industrial, automotive, and heavy-duty applications. With options like NF and NC types, these bearings offer additional solutions for applications needing axial load support in specific directions.
