Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.

Bearing Test Machine the extent of their savings is obvious
The use of wind turbines, wind energy is an endless stream of electricity into a standard household use us, the extent of their savings is obvious, a cost of household electricity only 20 yuan a year of battery fluid. And now the wind turbines have more than a few years radial clearance ago greatly improved performance, previously only be used in a few remote areas, wind turbines connected to a 15W bulb direct electricity, out of a dark and often damage the bulbs. And now because of advances in technology, the use of advanced chargers, inverters, wind power has become a certain tech small systems, and can replace the normal electricity under certain conditions. Mountainous can take the system to make a perennial street at no cost; it can be used to make highway signs night lights; mountain children can study up under Ball screw support bearing a fluorescent lamp; high-rise roof wind motor city also available, which will not only save but the real green Power. Domestic wind turbines, not only can prevent blackouts, but also increase interest in life. In tourist areas, border, schools, military and even behind the mountains, wind turbines are becoming the people's purchasing hot spots. Radio enthusiasts use their own technology in wind power generation services for the mountain people, so that people watch television and lighting, electricity and urban synchronization, but also make their own labor to get rich.
