 NACHI Founded in 1928, NACHI Bueryue has been committed to the development of machinery technology and machinery manufacturing since its inception. The main factory is located in Toyama, Japan. It also has production bases in North America, South America, Europe and Asia. It has set up permanent representative offices and sales outlets around the world, which can quickly and accurately grasp the market trend and effectively meet customers' wishes.
Its products mainly include: special steel, cutting tools, bearings, hydraulic devices, robot systems, cutting tools, machine tools, bearings, hydraulic equipment, robots for automatic production, special steel, ultra-precision machinery and environmental systems for the IT industry, etc. NACHI bearing is currently one of the four famous bearing brands in Japan.
NACHI can produce products that cover almost all mechanical industries, including robot systems, lathes, tools, automobiles, large equipment, etc.
advantage
(1) Reduce friction and friction loss.
In the mutual contact part of the ring, rolling element and retainer of the bearing, metal contact is prevented and friction and wear are reduced.
(2) Extend fatigue life.
The rolling fatigue life of the bearing is extended if the rolling contact surface is well lubricated during rotation. On the contrary, if the oil viscosity is low and the lubricating oil film thickness is not good, it will be shortened.
(3) Remove friction heat and cooling.
Circulating oil supply method can use oil to remove heat generated by friction or heat transmitted from outside for cooling. Prevent the bearing from overheating and the lubricating oil from aging.
NACHI bearing action
Its function should be support, which is literally used to support the shaft, but this is only part of its function. The essence of support is to bear radial load. It can also be understood that it is used to fix the shaft. It is to fix the shaft so that it can only rotate and control its axial and radial movement. The consequence of the motor without bearing is that it cannot work at all. Because the shaft may move in any direction, and the motor requires that the shaft can only rotate when it works. In theory, it is impossible to realize the function of transmission. In addition, the bearing will also affect the transmission. In order to reduce this effect, good lubrication must be achieved on the bearings of high-speed shafts. Some bearings have lubrication, called pre-lubricated bearings, while most bearings must have lubricating oil. When the load is running at high speed, friction will not only increase energy consumption, but also easily damage the bearings. It is one-sided to change sliding friction into rolling friction, because there is something called sliding bearing.
