Introduction of Block Bearing
Insert bearing with housing is a kind of bearing unit that combines rolling bearing and bearing housing. Most outer spherical bearings are made of spherical outer diameter and are installed with imported bearing housings with spherical inner holes. They have various structural forms, good versatility and interchangeability.
At the same time, this type of bearing also has a certain degree of self-alignment in the design, easy to install, and has a double structure sealing device, which can work in harsh environments. The bearing housing is generally formed by casting. Commonly used seats are vertical seat (P), square seat (F), convex square seat (FS), convex round seat (FC), diamond seat (FL), ring seat (C), slider seat (T )Wait.

Outer spherical UK bearing with tapered bore; Outer spherical bearing with seat is a high-precision component product composed of a grease-sealed deep groove ball bearing and various shapes of bearing seats. The bearing assembly can be directly mounted on the body of the mechanical device through several bolts. It has a self-aligning function and can be replenished with grease.
When removing the bearing for inspection, make a record of its appearance by taking pictures or other methods. In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearings.
Inspection and differentiation
In order to distinguish whether the dismantled bearing can be used from scratch, it is necessary to focus on checking its standard accuracy, rotation accuracy, internal clearance, cooperation surface, raceway surface, adherence frame and seal ring. As for the inspection effect, it can be distinguished by the conventional bearing or the person who knows the bearing. The different criteria differ according to the mechanical function and importance, and the inspection cycle. If the following damage occurs, the bearing must not be used from scratch and it must be replaced.
