Miniature Ball Bearings Micro-bearing refers to the metric series, the diameter of less than 9mm; British series, the diameter of less than 9.525mm various types of bearings! The main materials are carbon steel, bearing steel, stainless steel, plastic, ceramics, etc., which can be the smallest diameter 0.6mm, the general diameter of 1mm more.
In the ultra-small diameter micro-bearings, miniature deep groove ball bearings are metric 68 series, 69 series, 60 series, etc., the British R series of 6 kinds, on this basis, can be divided into ZZ steel dust Cover bearing series, with RS rubber seals miniature bearing series, Teflon bearing ring series and with flange series and so on.
Miniature Ball Bearings Miniature bearings for all types of industrial equipment, small rotary motors and other high-speed low-noise areas, such as:
Office equipment, miniature motor, instrumentation, laser engraving, small clock, soft drive, pressure rotor, dental drill, hard disk motor, stepper motor, video drum, toy model, computer cooling fan, cash register, fax machine And so on.
Miniature Ball Bearings Approximately 40% of the ball's micro-bearing failure is caused by dust, dirt, debris contamination and corrosion. Pollution is usually caused by improper use and poor use of the environment, it can cause torque and noise problems. The failure of micro-bearings produced by the environment and pollution is preventable, and it is possible to determine the cause of such failure by simple visual observation. As long as the use and installation of reasonable, miniature bearing erosion is easy to avoid. The denudation is characterized by the indentation on the micro-bearing ring raceway resulting from an impact load or an incorrect installation. The denudation usually occurs when the load exceeds the material yield limit. If the installation is not correct so that a load across the micro-bearing ring will produce denudation. The pit on the miniature bearing ring also produces noise, vibration and additional torque.
