The Difference Between Crossed Roller Bearings And Traditional Single-Row Deep Groove, Four-point and Angular Contact Bearings

Compared with traditional bearings, cross-roller bearings have the following differences:
1.
Structural differences: The internal structure of the cross-roller bearing is more complex, consisting of multiple cross-arranged rollers and raceways. In contrast, the ordinary bearing only comprises one roller and one raceway.
2.
Stronger bearing capacity: Due to the large number of rollers and contact points inside the crossed roller bearing, its bearing capacity is higher and it can withstand greater radial and axial loads.
3.
Higher accuracy: The internal structure of the cross roller bearing is complex and requires high-precision processing and assembly, so it can meet the requirements of high-speed and high-precision work and has higher accuracy.
4.
Longer service life: The larger contact area between the inner rollers and the raceway of the crossed roller bearing reduces friction and wear, thereby extending the service life.
5.
Easier installation: The compact internal structure and small external dimensions of the crossed roller bearing make installation easier and save space.

Compared with traditional single-row bearings, crossed roller bearings have advantages such as higher load-bearing capacity, higher precision, longer service life, and easier installation. Therefore, they are widely used in mechanical equipment under high-speed, high-precision, heavy-duty, and complex working conditions.
More precisely, cross-roller bearings are a type of precision bearing. Precision bearings are bearings manufactured under strict processing and assembly conditions, with characteristics of high precision, high reliability, high load capacity, and long service life. They are widely used in high-speed, high-precision, and high-reliability mechanical equipment.
Crossed roller bearings have complex internal structures and require high-precision machining and assembly to meet mechanical equipment requirements under high-speed, high-precision, heavy-duty, and complex operating conditions. Therefore, they are widely used in industrial robots, CNC machine tools, aerospace equipment, and other fields, and belong to a type of precision bearing.
