Two single-row angular contact ball bearings combined on the back of the structure share the inner ring and outer ring, which can bear radial load and bidirectional axial load. Sealed type bearings without filling groove. Mainly applicable cage: steel stamping cage (bowl shape.. Deep groove ball bearing. The most representative rolling bearing, widely used.

Can bear radial load and bidirectional axial load. Suitable for high-speed rotation and occasions requiring low noise and low vibration. Sealed bearings with steel dust caps or rubber seals are pre-filled with an appropriate amount of grease. Bearings with a stop ring or flange on the outer ring, which are easy to locate in the axial direction, and are easy to install in the housing.

The size of the maximum load bearing is the same as the standard bearing, but there is a filling groove in the inner and outer rings, which increases the number of balls and increases the rated load.Mainly applicable cage: steel stamping cage (wave, crown shape. Woodworking machinery, textile machinery drive shaft, vertical belt seat self-aligning bearing.

The cylindrical roller is in line contact with the raceway, and the radial load capacity is large, that is, it is suitable for bearing heavy loads and impact loads, and also suitable for high-speed rotation. N-type and NU-type can move axially, and can adapt to thermal expansion or installation errors. According to the difference of the internal structure, it is divided into four types: R, RH, RHA and SR mechanical bearings manufacturers Since the arc center of the outer ring raceway is consistent with the bearing center, it has self-aligning performance, so it can automatically adjust the axis misalignment caused by the deflection or misalignment of the shaft or housing.

Can bear radial load and bidirectional axial load. According to the state of the bearing, the clearance can be divided into the following three types: Original clearance. The clearance in the free state before the bearing is installed.2RS, 23. The maximum amount of movement in the radial direction is called radial clearance, and the maximum amount of movement in the axial direction is called axial clearance.
