What is a Double row angular contact ball bearing?

A Multi-Row Angular Contact Ball Bearing is a type of bearing that consists of several rows of angular contact balls. These bearings are designed to provide high load capacity and rotational precision. The angular contact design allows the balls to contact the inner and outer rings at an angle, making them suitable for handling both radial and axial loads simultaneously, unlike standard bearings.

The multi-row design offers even higher load capacity compared to single-row angular contact ball bearings and is particularly used in applications that require high precision or have complex load conditions. Examples of applications include machine tools, robot arms, aircraft engines, and precision measuring instruments.

Application of Double row angular contact ball bearing

１．Machine Tools: In precision machinery like CNC lathes or milling machines, multi-row angular contact ball bearings ensure stability during high-speed operation and maintain the accuracy of the axis.
２．Robot Arms: Multi-row angular contact ball bearings are used in robotic arms, where precise positioning and high load-bearing capabilities are required.
３．Aircraft Engines: In aircraft engine parts or turbine systems, multi-row angular contact ball bearings are employed to ensure high rotational precision and load-bearing capacity.
４．Precision Measuring Instruments: Multi-row angular contact ball bearings are also used in high-precision measuring instruments (such as optical devices or metrology equipment) to maintain accuracy and stability.
