Deep Groove Ball Bearing was originally listed as radial ball bearing, which is the most widely used rolling bearing. Its characteristics are low frictional resistance, high rotational speed, and can be used on components that can withstand radial loads or combined radial and axial loads, as well as on components that can withstand axial loads.
The self-aligning ball bearing has two structures: cylindrical hole and conical hole, and the material of the cage includes steel plate, synthetic resin, etc.
The cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bearing radial loads. The friction between the rolling element and the collar edge is small, suitable for high-speed rotation.
Self aligning roller bearings have double row rollers, with one shared spherical raceway on the outer ring and two raceways on the inner ring that are tilted at an angle relative to the bearing axis.
Needle bearing is a roller bearing with cylindrical rollers, which are both thin and long relative to their diameter. This type of roller is called a rolling needle.
Angular Contact Ball Bearings can withstand both radial and axial loads simultaneously. Capable of operating at higher speeds.
