NSK bearing seals are more infiltrated than dust caps and are subject to shifting responsiveness and lower speed relocation transitions. The painter must consider the smoothing agent's function and delivery system and hopes when selecting the proper seals. condition.
Alignment rolls NSK bearings are subjected to high loads, high impact forces, and water and rust intrusion during operation; NSK has developed a new type of ultra-high load capacity sealed, clean and smooth roll NSK bearings. NSK bearings can increase load capacity by 34%; have higher reliability; can be used for long-term operation under harsh and smooth conditions. It improves the NSK bearing function after sealing; blends optimized technical description, new materials and seals patented technology, And easy to operate equipment.
The main seal and width constrain the length of the roller; that is, the load of the NSK bearing is constrained. Therefore; they are in the description of the new roll NSK bearing; the edge of the shelf is included in the free space of the seal; the roller can be made longer How to make the diameter of the frame increase and the roller lengthen; while the length of the frame does not increase; the basic additional load capacity of 34% increase is reached; the equivalent of 27 times the NSK bearing life of the NSK bearing. The quality "T-F" selected for the NSK bearing. NSK bearing steel; is also the key to improve NSK bearing function; due to the impurities and smooth unevenness in the assessment is the primary cause of NSK bearing premature failure.
Resume marked; under contaminated working conditions; NSK bearings are easy to enter debris; and these crumbs damage the raceway; constitute stress gathering. In addition; assume smooth unevenness; make the metal surface hard touch; constitute a subtle "peeling" Damage; can also cause stress concentration in the touch area; these two effects cause the metal surface of the stress gathering site to crack, and shorten the NSK bearing life.
