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.

Timken bearing applications of large fan articles
We know that the company should be invented Timken tapered roller bearing set up, has now become the world's largest manufacturer of tapered roller bearings, Timken bearings distributor in China, today to tell you about Timken tapered roller bearing applications of large fan articles.
Timken bearings are widely used in a variety of standard gear box fan, direct drive wind turbine and hybrid fan. For these large wind turbines, Timken can provide many products, including tapered roller bearings (TS single row, double row TDI-based, dual-spherical outer diameter and spindle type TDODA oversized double row tapered roller bearings) , cylindrical roller bearings, and integrated planetary gear bearing components.
Timken tapered roller angular contact ball bearing designed to carry both radial forces have combined loads of axial force designed in wind speed and direction are subject to change circumstances, is the ideal choice to control stress. This kind of bearing high power density, in the most compact layout provides the best performance. For fans with a main gearbox planetary gearbox applications, Timken has developed two innovative products: Planet-Pac Bearing (integrated planetary gear bearing assembly) and Integrated Flexpin Bearing (IFB, namely integrated IFB ). Integrated planetary gear bearing assembly of the tapered roller bearing outer ring gear integration, avoiding the outer ring generated by wear and tear. Simple and compact design reduces the system cost.
Different types of Timken's tapered roller bearings in the fan box in both the spindle and the growth rate has been widely used for long-term stable operation of the fan to provide protection. In addition to models outside of Timken bearings, Timken company also provides lubrication products, sealing products, condition monitoring, maintenance tools and bearing repair services, provide users with full support for the fan to further improve equipment reliability and improved performance, Timken bearings used in large wind turbines on, in order to improve energy efficiency and reduce system cost has made important contributions.
