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.

double row tapered roller bearing
Environmental protection is one of today's society a constant topic today,bearings distributor in China and introduce you to the future SKF technology environmental protection. in the maintenance and operational experience in the field helps to make existing operations more streamlined and efficient, and applied to the new design and the concept of alternative energy sources such as theexpertiseBearing life testing machine and technology is more regarded as extraordinary.
in the wind and other renewable energy sources has extensive experience in the field. For example, an innovative series of Nautilus bearing solutions enable wind turbine manufacturers to abandon the spindle, thereby reducing the weight of the generator, reducing size and friction, ultimately increase this clean, renewable energy production. SKF bearings, seals and lubrication systems also help extend the life of solar energy equipment, particularly in harsh environments and extreme double row tapered roller bearing temperatures. actuators and control unit helps to make the building self-regulating system blinds warmer in winter, cooler in summer. Such a system equipped with products can reduce HVAC (HVAC) Energy consumption: 30-35% decrease in winter, summer reduced by half.
Transportation is the use of new technology to improve the environment a key. integrated components (from the engine and gearbox to the final drive and wheel) to reduce friction and reduce weight, thereby helping to reduce vehicle fuel consumption future. For example, for the final drive pinion unit of SKF hybrid can reduce carbon dioxide emissions per kilometer 3 g. In the airline industry applications, adopt a strong and lightweight titanium and other advanced materials integrated components, and the use of wire flight control system, helps to reduce weight and improve fuel efficiency.
