Ball bearing hub are the most common type of rolling bearings

Ball bearing hub bearings are the most common type of rolling bearings.
This type of ball bearing hub deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls, and a retaining structure.
There are two types of ball bearing hub deep groove ball bearings: single row and double row.The deep groove ball structure is also divided into sealed and open structures.Open refers to the bearing without a sealed structure, while sealed deep groove balls are divided into dustproof seals and oil proof seals.
The material of the dustproof sealing cover is steel plate stamping, which only plays a simple role in preventing dust from entering the bearing raceway.The oil proof type is a contact oil seal, which can effectively prevent the leakage of lubricating grease inside the bearing.

Ball bearing hub are the most representative rolling bearings with a wide range of applications. Suitable for high-speed or even extremely high speed operation, and very durable without frequent maintenance. This type of ball bearing hub bearing has a small friction coefficient, high limit speed, simple structure, low manufacturing cost, and is easy to achieve high manufacturing accuracy.

When selecting a larger radial clearance, the axial bearing capacity increases, and the contact angle is zero when subjected to pure radial forces. When there is axial force, the contact angle is greater than zero.
Generally, stamped wave shaped cages are used, vehicle made solid cages are used, and sometimes nylon frames are also used.
After installing the ball bearing hub, within the axial clearance range of the bearing, it can limit the axial displacement in both directions of the shaft or shell, and therefore can perform axial positioning in both directions.
