Industries Served As axises of all kinds of electrical machines, motors and electric tools. Functions and Characteristics 1.High quality. The products have a good ability in insulation and can withstand voltage reaches 6.8KV. (The highest standards at home and abroad is only 5KV) They can bear the heat up to 150 centigrade with the high mechanical strength and accurate dimension. The tolerance in both inside and outside diameter is not more or less than 0.02mm. 2. Low cost. The technics is easy to grasp because the direct pressure has shortened the process. 3. High environmental protection. The products are both green and healthy without grinding dust of BMC. 4. The products conform to the European standard ROHS green authentication.
