Bearings provide decrease in friction and transfer of efforts in the adjoining parts.
Depending on the cost of the bearing and from workmanship of its components, the following characteristics can change:
- Maximum dynamic and static load;
- Maximum speed;
- Requirements to lubricant;
- Bearing resource before emergence of signs of fatigue;
- Noise of the bearing.
The industrial bearing is not folding node from two rings between which balls slide. Prom the bearing is pressed in the mounting face and can be replaced if necessary.
Advantages of bulk bearings — low cost and possibility of adjustment in the course of wear. The last at the same time is also shortcoming as the possibility of adjustment means also its need: the lyuftyashchy or drawn bearing lives very not for long.
