Miniature Deep Groove Ball Bearings Micro-deep groove ball bearings refers to the metric series, the outer diameter of less than 9mm; inch series, the outer diameter of less than 9.525mm various types of bearings, the main material is carbon steel, bearing steel, stainless steel, plastic, ceramics, including the smallest diameter can be done 0.6mm, the general diameter of 1mm more.
Miniature Deep Groove Ball Bearings Product Features
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 Deep Groove Ball Bearings The main purpose
Suitable for all kinds of industrial equipment, small rotary motor and other high-speed low-noise areas, such as: office equipment, micro-motor, instrumentation, laser engraving, small clocks, soft drives, pressure rotor, dental drill, hard drive Into the motor, video drums, toy models, computer cooling fans, Dianchao Ji, fax machines, and so the relevant areas.
Miniature Deep Groove Ball Bearings Miniature bearing failure reasons
About 40% of the failed miniature deep groove ball bearings are 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.
