Precision Gem-bearings/ jewel bearing / Watches' gem-bearings
General Description
1. We are specialized in precision machining of super hard materials, esp. in micro-appliances including deep-hole thin wall ring magnet elements, enjoying a high competitiveness within market both at home and abroad.
2. The specific shape and size can be available by producing according to different drawing designs from customers.
3. The hole/(OD-ID)can be drilled to within a range of 0.1mm~3mm at our end. The various magnet can be widely used to make into super hard micro magnetic precision parts for timekeeper, micro-motor, optical communication electronics, electroacoustics, digital camera etc.
4. SmCo magnet is a kind of permanent magnet mainly made of RE samarium, metal Cobalt and other elements. It features high energy product, very low temperature coefficient, and a relatively stable magnetic property under high temperature(with max temperature up to 350°C).
5. Besides, with strong anti-corrosion resistance, generally it doesn’t need any electroplating at all, it can widely applied in motor, meter, sensor, radar, magnetic drive and other high-tech areas.
Usage1. The main products are Watches'gem-bearings,instruments'gem-bearings.
2. Rotor magnet used for quartz watch or electrical meter counting step motor
