Single row cylindrical roller bearings are a popular type of bearing used across various industries due to their ability to handle heavy radial loads while maintaining high-speed performance. These bearings are ideal for applications requiring reliable and efficient operation in demanding environments, such as in industrial machinery, automotive gearboxes, and electric motors. In this guide, we’ll dive deep into the features, benefits, applications, and where you can buy high-quality single row cylindrical roller bearings, including why you should consider TradeBearings as your trusted supplier.
What Are Single Row Cylindrical Roller Bearings?
Single row cylindrical roller bearings consist of an inner ring, an outer ring, cylindrical rollers, and a cage that holds the rollers in place. Unlike ball bearings, the rolling elements in cylindrical roller bearings are shaped like cylinders, which allows them to distribute loads more evenly across the bearing surface. This design is particularly effective at handling heavy radial loads but has limited capability for axial loads unless specially designed. You can see the example at https://en.tradebearings.com/NU38__M_C3-.html
Key Features:
High Load Capacity: The cylindrical shape of the rollers provides a larger contact area with the raceways, allowing for greater load-carrying capacity compared to ball bearings of the same size.
Low Friction: The design minimizes internal friction, enabling efficient operation even at high speeds.
Axial Displacement Capability: Some configurations, such as NU and NJ types, can accommodate axial displacement, making them ideal for applications with thermal expansion.
Multiple Designs: Available in different configurations (N, NU, NJ, NUP) to suit various application needs.
Types of Single Row Cylindrical Roller Bearings
There are several variations of single row cylindrical roller bearings, each designed to meet specific requirements:
N-Type Bearings:
Feature a rib on both sides of the inner ring, allowing axial movement of the shaft in both directions.
Best suited for free-end bearings that accommodate thermal expansion.
NU-Type Bearings:
The outer ring has two ribs, while the inner ring has no ribs.
These bearings are capable of handling radial loads and can also allow axial displacement.
NJ-Type Bearings:
The inner ring has one rib and can handle both radial and light axial loads in one direction.
Commonly used in gearboxes and industrial machinery.
NUP-Type Bearings:
Feature a rib on both the inner and outer rings, allowing the bearing to accommodate radial loads and light axial loads in both directions.
Ideal for applications requiring precise axial positioning.
Benefits of Using Single Row Cylindrical Roller Bearings
Single row cylindrical roller bearings are preferred for a variety of reasons:
Increased Load Capacity: The large contact area between the rollers and raceways allows for handling higher loads, making these bearings ideal for heavy-duty applications.
High-Speed Performance: The design minimizes friction, allowing for smooth and efficient operation at high speeds.
Durability and Longevity: Made from high-quality steel and designed for optimal load distribution, these bearings offer a long service life with minimal maintenance.
Versatility: Available in multiple configurations, single row cylindrical roller bearings can be used in a wide range of applications, from electric motors to wind turbines.
Common Applications of Single Row Cylindrical Roller Bearings
Due to their robust design and excellent performance characteristics, single row cylindrical roller bearings are used in various industries, including:
Automotive Industry:
Used in transmissions, gearboxes, and differentials, where high load capacity and reliability are crucial.
Industrial Machinery:
Widely used in heavy-duty machines such as compressors, pumps, and crushers, where they can handle high radial loads and provide smooth operation.
Electric Motors:
The low-friction design ensures efficient operation, making them a popular choice for high-speed electric motors.
Wind Turbines:
Single row cylindrical roller bearings are used in the main shafts of wind turbines, where they need to handle heavy radial loads and withstand harsh environmental conditions.
How to Choose the Right Single Row Cylindrical Roller Bearing
When selecting a single row cylindrical roller bearing, consider the following factors:
Load Requirements: Determine the radial and axial load capacity needed for your specific application.
Speed Rating: Ensure the bearing can operate efficiently at the desired speed without excessive friction.
Operating Environment: Consider the conditions the bearing will be exposed to, such as temperature, humidity, and potential contaminants.
Bearing Configuration: Choose the right bearing type (N, NU, NJ, or NUP) based on the axial movement and load handling requirements.

The main difference between cylindrical roller bearings and other bearing styles is in the name – they use cylinders as the rolling elements as opposed to the balls you’d find in ball bearings. The cylinders are slightly greater in length than diameter. Compared to ball bearings, cylindrical rollers have a greater radial load capacity. The cylindrical roller design also allows these parts to accept relatively faster speeds than other styles of roller bearings.
There are multiple types of cylindrical roller bearings. Single row cylindrical rollers are the most popular and are separable, which makes for easier mounting and dismounting. However, these may not be able to support the radial load of certain applications. Double row and multi-row cylindrical roller bearings offer greater radial load capacity and can also transmit axial loads in one direction.
Like other styles, cylindrical roller bearings have various clearance and lubrication options available depending on the manufacturer and supplier. Cylindrical roller bearings can be made with a cage or as a full complement part.
The company is the world’s best German Sealed Cap supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
Like all other types of bearings, cylindrical rollers require care and maintenance. Flaking or pitting, cracking and chipping, scratches, and rust are among the most common causes of cylindrical roller bearing failure.
Fortunately, you can limit the risk of bearing failure. There are preventative measures you can take to reduce the risk of bearing damage. Check out our posts on what you can do to help prevent or detect the following potential problems:
- Contamination, improper mounting, and misalignment
- Corrosion, lubrication, fluting, and fatigue
- Overheating, excessive loads, improper storage or handling, and improper fit
