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.

designed for harsh operating environments far from the sea and design
FAG bearings used in the spindle MULTIBRID company fans
Recently , FAG is MULTIBRID company 5MW wind turbine project, the design and development of the fan shaft weighing seven tons of large FAG double row tapered roller taper roller bearing FAG bearings used in MULTIBRID company fans FAG spindle bearing applications in MULTIBRID company fans spindle. Here FAG distributor in China to tell you about the application in MULTIBRID company fans FAG spindle bearings.
MULTIBRID company developed a 5MW wind turbine , designed for harsh operating environments far from the sea and design. FAG Group took only eight months , the production took six months. The FAG bearing performance, an outer diameter of 3200mm, the hole diameter is 2620mm, width 485mm, weighs more than 7t. All the bearing inner and outer rings and rolling elements are made of high-grade steel FAG bearing manufacturer . FAG double row tapered roller bearings are rolling through the middle pin-type cage design, it can be placed close to the full complement cylindrical roller number of rollers , this design ensures bearing in very bad conditions can operate reliably , for example, in the tunnel shield machine in there are many successful applications of experience. FAG rolling bearings used through the middle pin-type cage designed to ensure the bearing in very bad conditions can operate reliably .
FAG double row tapered roller bearing preload internal use of light to achieve optimum load carrying capacity . Lubricated by circulating oil lubrication , lubricating oil through the front main bearing into the gear box will be filtered. In order to ensure the durability of the oil , any contamination must be avoided . Better quality lubricant oil itself determines a longer life , but also help extend bearing life.
