What are the uses of cylindrical roller bearings?

Cylindrical roller bearings play an important role in multiple fields and scenarios due to their unique structure and characteristics. The following are some of the main uses of 

cylindrical roller bearings:

Bearing heavy loads and impact loads: Cylindrical roller bearings have a large radial bearing capacity and are suitable for bearing heavy loads and impact loads. Therefore, 

they are widely used in situations where they need to withstand large pressures and impacts.

High speed rotation: The rolling elements of cylindrical roller bearings have low friction with the ring edge, making them suitable for high-speed rotation. The maximum 

speed is close to that of deep groove ball bearings, which makes them very useful in high-speed equipment.

Axial positioning: Some types of cylindrical roller bearings, such as NJ and NF types, can withstand a certain degree of axial load and can be used as fixed side bearings for 

equipment to achieve axial positioning.

Adapting to high loads, low noise, and high speeds: Cylindrical roller bearings have the characteristics of high loads, low noise, and high speeds, making them suitable for 

occasions that require high efficiency and low maintenance costs.

Separable bearings: Cylindrical roller bearings are mostly separable, making them easy to install and disassemble, which is very advantageous for situations that require 

frequent replacement or maintenance.

Specific industry applications: For example, cylindrical roller bearings are widely used in machine tool spindles, rolling mills, rollers, grinders, and large gearboxes due to 

their high load capacity and good rotational performance.

Bearing large loads and impacts: In places with medium and low-speed loads such as construction machinery, vehicles, steel, and lifting machinery, fully loaded cylindrical 

roller bearings can withstand larger loads and are suitable for these high-speed and high-precision applications.

High speed and high-precision applications: Four column cylindrical roller bearings are particularly suitable for applications that require high speed and precision, such as 

support for wire mills, profile mills, thin plate cold and hot rolling mills, and cutting machines.

In summary, cylindrical roller bearings play an indispensable role in many industrial fields due to their unique structure and excellent performance, from high-speed 

rotating equipment to applications that withstand heavy loads and impacts.
