The difference between ball bearings and cylindrical roller bearings

The main differences between ball bearings and cylindrical roller bearings lie in their structure, performance, and application scenarios.

Structural differences

Ball bearing: The rolling element of a ball bearing is a spherical alloy steel ball, installed between the inner and outer steel rings, which reduces friction and improves mechanical power

transmission efficiency through rolling

Cylindrical roller bearings: The rolling elements of cylindrical roller bearings are cylindrical and designed to perform well under high radial loads and relatively low axial loads

performance differences

Ball bearings :

Weak bearing capacity: Due to the small bearing area of ball bearings, mechanical damage is prone to occur during high-speed operation, making them suitable for lightly loaded mechanical

transmission equipment

High speed: Ball bearings have a high speed and are suitable for applications that require high speed and low noise

Cylindrical roller bearings:

Strong load-bearing capacity: Cylindrical roller bearings can withstand high radial loads and relatively low axial loads, suitable for high-speed rotating applications

Large size: Due to the design of its cylindrical rolling elements, the size of cylindrical roller bearings is relatively large

Differences in application scenarios

Ball bearings:

Light industrial machinery: Due to its suitability for low load mechanical transmission equipment, ball bearings are commonly used in applications such as electric tools, automotive engines,

and motors that require high speed and low noise

Cylindrical roller bearings:

Heavy Machinery: Cylindrical roller bearings are suitable for applications that require high radial loads and low axial loads, such as cranes, metallurgical equipment, plastic machinery, and

engineering machinery
