Outer spherical bearing with seat is usually composed of rolling bearing and bearing seat. The outer ring of the bearing is usually made into spherical shape, which is installed and used in combination with the spherical inner hole bearing seat. The outer spherical bearing with seat has various structural forms, and has good versatility and interchangeability. At the same time, it also has a certain centricity, easy to install and double sealing structure device.
Characteristics of spherical bearing with seat
With automatic centering function
The outer diameter of the bearing and the inner diameter of the bearing seat are spherical, with automatic centering function, which can effectively compensate for the misalignment of the axis caused by installation and the deformation of the installation bottom surface
Large load capacity
The internal structure of the outer spherical ball bearing can be the same as the 6200 and 6300 series of the deep groove ball bearing, so the FS outer spherical ball bearing with seat can bear radial load and certain axial load. And the working noise is low.
Long service life
The spherical ball bearing with seat can work and operate in harsh environments such as soil, dust, humidity and high temperature, but it is necessary to replace the grease to ensure the proper lubrication interval and amount. Generally, FS with cast iron outer spherical ball bearing is equipped with grease nozzle to facilitate re-lubrication and ensure its perfect performance and service life.
Excellent sealing performance
Outer spherical ball bearing usually requires a combined sealing device with heat and oil resistant rubber sealing ring and steel dust cover. The dust cover is usually installed on the outer diameter of the bearing inner ring and rotates with the inner ring, effectively preventing foreign matters from entering and resisting external deformation pressure,
Robust bearing seat
The bearing seat is usually of integral seat structure and has excellent rigidity, which can effectively prevent the deformation of the bearing
