What is a bearing unit and where does it apply?

To avoid unplanned downtime and increase the operating costs of industrial equipment, it is worth choosing a bearing unit that will be durable and reliable. Due to the wide variety of bearing housings, seal types, and shaft mount configurations, choosing the right bearing unit for your equipment may seem like a daunting task. Therefore, it is worth finding out what factors should be taken into account. In our post, we will tell you what a bearing unit actually is and where it can be used. We invite you to read.

Construction of bearing units

In the case of industrial devices, such as e.g. chain conveyor, the precise selection of the bearing and drive is critical to the continuity of production. The elements included in the bearing units in machines are:

  • fixtures bearing type P, F and T - split or non-split, most often made of cast steel or cast iron, equipped with various types of seals - many options for mounting on the shaft; in the food industry, standard reinforced polyamide housings are used or, if increased resistance to chemicals is required, polypropylene bearing housings are used;
  •  grease supply valve - it is an accessory of the bearing housing;
  •  bearings - made of chrome-nickel steel or stainless steel - usually self-aligning, these may be: deep groove, angular contact or self-aligning ball bearings; cylindrical roller bearings, tapered roller bearings, spherical roller bearings, needle roller bearings;
  •  sealants and covers - installed in bearing housings, they provide additional bearing protection;
  •  bearing insert.

Application of a bearing assembly

Due to the properties of individual bearing units, we can use them in many environments, even those demanding and polluted. For example, in the food industry, high resistance to chemicals used for cleaning devices is necessary, so pivoting bearing units with a plastic housing will be perfect here. On the other hand, a bearing unit with a spherical roller bearing in a non-split housing can be installed in a conveyor and used in a coal mine.

In addition, the bearing unit is installed in machines operating in agricultural, construction, textile, energy and wood industry production.
