Rolamento is an important basic part of all kinds of mechanical equipment

Rolamento is an important basic part of all kinds of mechanical equipment. Its precision, performance, life and reliability play a decisive role in the precision, performance, life and reliability of the main engine.In mechanical products, the bearings are high precision products, not only need comprehensive support the theory of mathematics, physics, and many other disciplines, but also need to material science, heat treatment technology, precision machining and measuring technology, numerical control technology and effective numerical method and the powerful computer technology in many disciplines, such as services, thus bearing is a product on behalf of the state science and technology strength.

Rolamento is an important part of modern mechanical equipment.Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its turning precision.
It can be divided into rolling rolamento and sliding rolamento according to the frictional properties of motion elements.The rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial dimension, vibration and noise are larger, and its price is higher.
The seal of rolamento can be divided into self-sealing and external sealing.The so-called bearing with seal is the bearing itself made into a sealed performance device.Such as bearing with dust cover, sealing ring, etc.This seal occupies very little space, is easy to install and disassemble, and the cost is relatively low.

Rotating bearings are needed for everything from heavy-duty wheel axles and machine tool spindles to sophisticated clock parts.The simplest type of rotary rolamento is the bushing bearing, which is simply a bushing clamped between the wheel and the axle.This design was subsequently replaced by rolling bearings, which replaced the bushing with a number of cylindrical rollers, each of which acted as a single wheel.
