The outer sphere ball bearing is actually a variant of the deep groove ball bearing, characterized by its outer ring outer diameter surface for the sphere, can be matched into the corresponding concave sphere of the bearing seat to play the role of alignment, with seat outer sphere bearing is a rolling bearing and bearing seat combined together a bearing unit. Most of the outer spherical bearings are made of spherical outside diameter, and with a spherical bore bearing seat mounted together, the structure of various forms, versatility and interchangeability is good.

At the same time, these bearings are also designed with a certain degree of alignment, easy to install, with a double structure of the sealing device, can work in harsh environments.

Features

1、With self-aligning function

The outer diameter of the bearing and the inner diameter of the bearing housing are spherical fits, and the two have an auto-aligning function, which can compensate for the non-coincidence of the axis and the deformation of the installation bottom surface due to installation errors.

2、Large load capacity

As the internal structure of the outer spherical ball bearing is the same as the 6200 and 6300 series deep groove ball bearings, thus the outer spherical bearing with seat can not only bear radial load, but also bear certain axial load, and at the same time the working noise of the bearing is small.

3、Excellent sealing performance

The outer spherical ball bearing has heat-resistant, oil-proof rubber seal and steel plate dustproof cover combination seal on both sides, dustproof cover assembled on the outer diameter of the inner ring of the bearing and the inner ring together with the rotation, can effectively prevent external foreign matter from entering the bearing, and can resist external pressure to protect the bearing, this combination of sealing ring and dustproof cover can prevent mud, dust, moisture into the bearing, and at the same time can prevent the bearing internal grease from leaking out. This enables the bearings to maintain perfect working performance even under harsh working conditions.

4、Sturdy bearing housing

The bearing housing is of integral housing structure, which is rigid and prevents the bearing from being deformed during assembly and is durable under any working conditions.
