Industrial bearings are essential mechanical components that reduce friction and support rotational or linear motion in machinery systems. They help improve operating efficiency, reduce wear, and extend equipment lifespan. Depending on their design and function, bearings can support radial loads, axial loads, or both.
ome Common Types of Industrial Bearings
1. Classification of Industrial Bearings
There are several ways to classify bearings. Below are the most common groups based on design and application:
1.1. Ball Bearings
Ball bearings are the most widely used type. They use balls placed between two raceways to minimize friction. They offer good radial load capacity and high-speed performance but are limited under heavy axial loads. Thanks to their simple design and high efficiency, ball bearings are used in electric motors, water pumps, gearboxes, and industrial fans.
Kyo bearing
Popular types:
-
Single Row Ball Bearings (e.g., 60xx, 62xx, 63xx)
-
Double Row Ball Bearings – better load capacity
-
Angular Contact Ball Bearings (e.g., 52xx, 32xx, 72xx, 73xx) – good axial load support.
1.2. Cylindrical Roller Bearings
These bearings use cylindrical rollers instead of balls, increasing contact area and radial load capacity. They offer low friction and high-speed operation but are not ideal for heavy axial loads. Commonly used in industrial gearboxes, crushers, and steel mills.
Industrial Cylindrical Roller Bearings
Common Types of Cylindrical Roller Bearings:
-
Single Row Cylindrical Roller Bearings (NU, NJ, NUP, N, NF) – suitable for high-speed applications with medium load capacity.
-
Double Row Cylindrical Roller Bearings (NN, NNU) – designed for heavier load conditions.
-
Full Complement Cylindrical Roller Bearings – support very high loads but operate at lower speeds due to the absence of a cage.
1.3. Tapered Roller Bearings
Tapered roller bearings use conical-shaped rollers that can support both radial and axial loads simultaneously. These bearings are capable of handling very heavy loads and offer excellent shock resistance, although they generate more friction compared to ball bearings. They are commonly used in trucks, industrial gearboxes, and metal pressing machines.
Kyo Tapered Roller Bearings
Common Types of Tapered Roller Bearings:
-
Single Row Tapered Roller Bearings – designated as 302xx, 303xx, 320xx.
-
Double Row Tapered Roller Bearings – provide increased load-carrying capacity.
1.4. Self-Aligning Ball Bearings
Self-aligning ball bearings have two rows of balls and a spherical raceway that allows for automatic alignment, helping reduce the effects of shaft misalignment during operation. These bearings feature low friction and moderate load capacity, making them suitable for industrial pumps, high-capacity fans, and electric motors. Popular series: 12xx, 13xx, 22xx, 23xx.

1.5. Needle Roller Bearings
Needle roller bearings use long, thin cylindrical rollers with small diameters, allowing them to support high loads in compact spaces. However, they are not suitable for high-speed rotation. These bearings are commonly used in automotive transmissions, printers, and machine tools. Popular series: NK, NKI, RNA, HK.

1.6. Thrust Bearings
Thrust bearings are specifically designed to support axial loads and come in two main types: thrust ball bearings and thrust roller bearings. Thrust ball bearings are suitable for light loads and high-speed applications, while thrust roller bearings can handle heavier axial loads. They are commonly used in turntables and industrial rotary systems.
Industrial Thrust Bearings
Popular types:
-
Thrust Ball Bearings – light loads, 511xx, 512xx
-
Thrust Roller Bearings – heavy loads, 293xx, 294xx
2. How to Choose the Right Bearing
When selecting a bearing for machinery, consider the following:
-
Load type: Choose based on radial and/or axial load requirements
-
Rotational speed: Ball bearings handle high speeds, roller bearings handle heavy loads
-
Operating environment: Dusty or high-temperature environments require special lubrication
