Double Row Angular Contact Ball Bearing
Functions
In comparison to the single row angular contact ball bearing, the double row angular contact ball bearing can accommodate large combined loads with a large radial component and a small axial component, as well as a tilting movement. With a 30 degree contact angle, it can limit the bi-directional axial displacement of the shaft or casing. It is usually equipped with a nylon or brass cage.
Applications
Designed with a non-separable structure, this industrial bearing is suited for high speed applications where a high rigidity is required. This non-separable radial bearinghas been widely wheel hub for automobile front wheels (double row tapered roller bearings that are the same size are also applicable to some cars), and have become increasingly popular precision bearings for car manufacturers, car part manufacturers and more.
These roller bearings can also be used for oil pumps, roots blowers, air compressors, gear boxes, fuel injection pumps, printing equipment, planetary reducers, extraction equipment, cycloidal reducers, food packaging equipment, and electric welding machines, electric soldering irons, square gearboxes, gravity feed spray guns, wire stripping machines, semi axles, inspection and analysis instruments, and fine chemical industry equipment.
