The so-called “Quest” is the “exploration and pursuit” of high performance and reliability. This is a new trademark marked on NACHI industrial machinery special high-performance bearings. This type of product condenses NACHI‘s accumulated technology in materials, machining and lubrication, and can provide users with bearings with high rigidity, strong durability, low noise, good environmental performance, and world-class quality.
Its products mainly include: special steel, cutting tools, bearings, hydraulic devices, robotic systems, cutting tools, machine tools, bearings, hydraulic equipment, robots for automated production, special steels, ultra-precision machinery and environmental systems for the IT industry.
Etc. Among them, NACHI bearing is one of the four famous bearing brands in Japan.
(1) Reduce friction and wear.
In the contact parts of the ring, rolling element and cage that constitute the bearing, metal contact is prevented, and friction and wear are reduced.
(2) Extend fatigue life. The rolling fatigue life of the bearing is prolonged if the rolling contact surface is well lubricated during rotation. Conversely, if the oil viscosity is low, the lubricating oil film thickness is not good, so it is shortened.
(3) Discharge friction heat and cool.
The circulating oil method can use oil to remove heat generated by friction or heat transferred from the outside and cool. Prevent the bearing from overheating and prevent the lubricant from aging.
