Oil seal spring is a spring on the oil seal ring, the length is between 20-5000mm, usually by the line diameter 0.15-1.0mm between the high quality carbon steel or stainless steel wire winded, its role is to seal card on the shaft, with better sealing. Are generally used in shock absorber oil seal or rotating seal, can strengthen the radial force, but also can play the role of compensation; when the oil seal used for a period of time after abrasion, oil seal spring will have to compensate radial force.

 
  The main performance index of oil seal spring:
  1、Length tolerance: ± (wire diameter x 1.5)
  2、wire diameter tolerance: ± 0.01mm
  3、winding diameter tolerance: ± 0.05mm
  4、The modulus at : connecting and fixing both ends of the spring, can resist the super length 10% elongation
  5、appearance: spring surface no oxidation or traces of pollution; knotting spring does not form the figure "8" in the external force is very weak; spring coil wound on the surface does not appear fluctuation.
  Oil seal spring has a tensile elastic labor-saving, strong and support characteristics such as good, its applicable fields have food machinery industry, hardware and rubber industry, locomotive, machinery and machine parts.
  Oil seal spring machine is a mechanical equipment used for processing oil seal spring, which is also commonly referred to as power 8 or eight type machine, such as Dongguan Kaichuang precision spring Machinery Co. Ltd. KCT-8C computer spring machine, the processing line diameter is 0.15-0.8mm, sometimes with a special mould can be completed 0.07mm spring processing, has the good stability and precision. 8 electrical machine is controlled by computer program, can store more than 1000 program instructions, a set up for later call program to use, very convenient. This machine can be equipped with inspection machine, high precision spring processing for; also can be equipped with a torsion spring device, processing some of the simple torsion spring and side ear spring etc..
