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.

NSK Bearings corrosion
NSK taper roller bearing distributor in China the news: Japan NSK has developed for acid and other corrosive environments NSK-performance corrosion resistant bearings, ring and outer ring through its newly developed materials used to make bearings in acid and other corrosive greatly extend the life environment, thereby reducing customer downtime and maintenance costs. We follow NSK NSK distributor in China to understand the corrosion-resistant bearings.
NSK rolling bearing corrosion resistant to corrosion and abrasion resistance of the ceramic balls, the inner and outer use of "high-hardness stainless steel of high corrosion ESZ", as compared with conventional bearing steel, the hardness increased by about 30%. If a corrosive environment is not particularly serious cases, life can be extended by 10 times.
NSK corrosion main dimensions of the bearing inner diameter of 10 ~ 60mm, outer diameter of up to 26 types of 110mm. NSK Bearings are mainly applicable to support the solar panels and LCD panels for use in high-performance thin-film drive roller, cleaning, disinfection and sterilization of medical equipment and other food machinery and handling equipment. Nippon Seiki Union Club (NSK) is expected to start from April 2010 sales, with sales target for the year 2011 was 300 million yen.
