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.

SKF Bearings can also withstand large overturning moment
In addition, the traditional pairing (or double row) tapered roller bearings, the contact angle is generally only about 20 °, while ensuring its larger radial load capability, bearing axial load carrying capacity and the ability to withstand the overturning moment subject to certain restrictions. SKF Bearing break through the traditional design of the contact angle, the contact angle of each single bearing enlarged to 45 °, in the bearing radial load capacity of the premise, greatly strengthened the axial load bearing capacity, while, SKF taper roller bearing can also withstand large overturning moment. Configuration of the conventional double bearing comparison, SKF Nautilus bearing load is applied to two lines of intersection of the center line from the axis is much longer than the general configuration of tapered roller bearings, these two points of intersection on a point of the support shaft runs. But also to adjust the bearing preload condition to optimize the rigidity of the system.
SKF Nautilus bearing as SKF Bearing Tapered Roller Bearing part of the sample. SKF Nautilus series bearings to improve wind turbine wind generator power at the same time, reduce their weight, reduce the manufacturing cost of the entire wind turbine for wind power producers who brought the most direct economic benefits.
