Do you know what a tensioner bearing is? See how it works   (1) Concept With the popularization and application of high-position camshafts and overhead camshafts in modern automobile engines, the synchronous chain transmission and gear transmission of camshafts have gradually been replaced by toothed belt transmissions. At the same time, the transmission of the fuel…

New Technology Development of High Reliability Single Row Cylindrical Roller Bearings for Machine Tool Spindles The use of a new type of roller guide cage to improve the production efficiency and reliability of the spindle-the new technology of machine tool spindle TIMKEN bearings developed by Seiko (hereinafter referred to as NSK) can reduce the workload during…

Introduction to knowledge of bearing friction and temperature rise   Bearing temperature rise: The friction of rolling  INA bearings is a key factor in determining bearing heating and operating temperature. The friction loss of the rolling bearing is almost all converted into heat inside the bearing, which causes the temperature of the bearing to rise. Generally,…

Introduction to the operation types of  NSK bearing annealing and normalizing   Normalizing is a kind of metamorphosis or special case of complete annealing. The two are only different in cooling rate. Usually annealing is cooled with the furnace and normalizing is cooling in air. Normalizing is suitable for both hypoeutectoid steels and super-eutectoid steels. For…
