The introduction of miniature bearing

Miniature bearing refers to metric series, outside diameter is less than 9 mm; Inch series, outer diameter less than 9. All kinds of bearing 525 mm! Main material is carbon steel, bearing steel, stainless steel, plastic, ceramic, etc. , including minimum inner diameter can be 0. 6 mm, inner diameter of 1 mm more commonly. Product features in ultra small aperture in the miniature bearing, miniature deep groove ball bearing type has the metric 68 series, 69 series, 60 series, etc. , inch on a total of 6 R series, based on this, also can be divided into with ZZ steel dust cover bearing series, rubber sealing ring with RS miniature bearing series, teflon bearings seals series, flanged penal series and so on. Miniature bearing has the following characteristics: 1, sealing form: open ( No cover) , metal shielding with dust cover ( ZZ) , the rubber sealing ring ( 2RS ） 。 2, the level of accuracy: ABEC - 1,ABEC - 3,ABEC - 5,ABEC - 7,ABEC - 9, according to the numerical value since the childhood, is becoming more and more high precision level. 3, speed: we can provide the maximum speed of 450000 RPM high speed miniature bearing, the high speed bearing is mainly used in the spindle, the drill mobile. We also for the jewelry, toys, industrial robots and other industries to provide low-speed bearing. 4, retainer: retainer is one of the most important parts of bearing, miniature bearing are usually chooses the retainer of the stainless steel material, but also have many customers like the nylon cage miniature bearing. 5 types: to distinguish from the model, small bearings including 68,69,60,62, MR series bearings. Traditionally we all become a miniature zero type bearing. 6, application: micro-motor, fitness equipment, telecommunications equipment, instrumentation, computer, automobile motor, precision instruments, machinery and equipment, home appliances, medical equipment, fishing gear, remote control toys, high temperature resistant, etc.
