deep groove ball bearing 685

685 is a type of zero miniature deep groove ball bearing product, where 6 is the deep groove ball bearing, 8 represents the bearing size series, 5 represents the bearing inner diameter size, ZZ/2RS represents the bearing on both sides with dust cover, has the role of preventing dust and other debris into the bearing, Common materials are bearing steel GCr15, stainless steel, carbon steel, ceramics, plastics, etc. The cage has a steel plate stamping cage, nylon cage, iron cage, copper cage, F1 carbon steel cage, and so on. Inner diameter 5 mm outer diameter 11 mm thickness 3 mm, mainly used for solenoid valve, plate spring, machine vise, packaging testing machine, sedimentation tank, nail machine, filtration equipment, colorimeter, instrument, motor, motor, electronic accessories, hardware parts, toys, and other equipment. The radial clearance of bearings is divided into original clearance, installation clearance, and working clearance. Usually, the initial radial clearance of the bearing is greater than the clearance of the bearing when it is working. Clearance is an important technical parameter of bearings, which directly affects the load distribution, vibration, noise, friction, service life, and mechanical motion accuracy, and other technical performance of bearings. Strictly speaking, the rated dynamic load of bearings varies with the size of clearance. The RATED loads (Cr and Cor) listed in the product sample are the load values when the operating clearance is zero. Excessive clearance will cause the bearing internal bearing area to decrease, the rolling contact surface stress to increase, the bearing motion accuracy to decrease, the vibration and noise to increase, and the service life of the bearing to shorten: such as if clearance is too small, it will cause heating up, and even lead to the bearing locked in operation. Therefore, it is very important to select different grades of bearing clearance according to the type and working conditions of bearings.
