How to maintain pillow block bearing units?

Pillow block bearing units) is a kind of bearing unit that combines rolling bearings and bearing housings. Most of the outer spherical bearings are made of spherical outer diameter and installed together with imported bearing seats with spherical inner holes. They have various structural forms and good versatility and interchangeability.

Pillow block bearing units are also designed to be self-aligning, easy to install, and have double-structured sealing devices that can work in harsh environments. The bearing seat is generally cast.
Pillow block bearing units are high-precision components composed of grease-sealed deep groove ball bearings and various shapes of housings. The bearing assembly can be directly installed on the main body of the mechanical device through several bolts, has the self-aligning function, can supplement the grease, etc. It is a product that is very easy to install and use.

Cleaning pillow block bearing units
When removing the pillow block bearing units for inspection, first take pictures and other methods to make a record of the appearance. Also, acknowledge the amount of remaining lubricant and sample the lubricant before cleaning the pillow block bearing units.
an examination
In order to distinguish whether the removed pillow block bearing units can be used again, it is necessary to focus on checking their standard accuracy, rotation accuracy, internal clearance, and the wear of cooperating surfaces, raceway surfaces, cages and sealing rings. Regarding the inspection effect, it can be judged by the usual pillow block bearing units or the reasonable users who know the bearing. In addition, the inspection period and inspection parameters can be different according to the different mechanical functions and uses and the importance of related factors. If the above damage occurs, the requirements for reuse cannot be met, and the pillow block bearing units shall not be reused and must be replaced.
