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.

processing technology applied to the product
Wazhou transformation of major equipment, the introduction of precision Bearing manufacturer highest level of internationally grinding center, so large precision bearings technology and equipment level reached international advanced level, while the introduction of foreign advanced processing technology, processing technology applied to the product. After transformation and innovation, to become China's major equipment ZWZ the highest level of precision bearings, the market share of the largest supplier of products to replace imports, in short supply.
ZWZ bearing turntable using the most advanced technological transformation projects turntable bearing production equipment, and supporting investment in testing and laboratory equipment, focusing on the development of wind power generation, medical equipment, port equipment and many other industries supporting the wheel bearings. Wind wheel bearing technology and equipment level and product level at or close to the international level of similar products, one to undertake a wind power equipment manufacturing enterprises Orders 240 million yuan, 300 million yuan this year to undertake the orders.
Precision bearings as the basis for precision parts manufacturing equipment, has restricted our equipment levels. ZWZ precision bearings on the new market-oriented transformation project, the introduction of international advanced bearing production equipment, in the short term so that our precision bearing technology and equipment level and product level has reached the international advanced level, a comprehensive import substitution. Currently, multi-standard, high-precision bearings have been successfully produced.
ZWZ bearing rail transit lines through technological transformation, to build a world-class speed automatic grinding equipment truck bearing production lines and heavy truck bearing production line to meet the domestic railway speed matching requirements, product quality has reached the international level of similar products. Now with the introduction and development of a combination of domestic, fully meet the speed heavy duty bearings supporting domestic requirements.
