Roller bearing

Roller bearings — also known as rolling-element bearings — are similar to ball bearings in that they are designed to carry a load while minimizing friction. However, roller bearings transmit loads using cylinder rolling elements, rather than balls, to maintain the separation between moving parts of the bearing. Bearing life is essentially the length of time a bearing can be expected to perform as required in predefined operating conditions. It is based primarily on the probable number of rotations a bearing can complete before it starts showing symptoms of fatigue, such as spalling or cracking due to stress. #rollerbearing #mechanism #bearing #инженерия #工程
