Construction features: They are both positioned with bare spindle blade. The bobbin is driven by pin bolt or tenon. The upper support is rigidly connected. The axial motion has buffer actions. The lower support is elastically connected. The working spindle, in high speed rotary, has radial self-adjusting functions. The big ring springs, with the help of the attenuation by multilayer oil films, are able to reduce the amplitude of the spindle in operation.

Construction features: Connected with elastic metal tubes; the upper bearing fixed; the lower support having crosswise self-adjusting centre and driven buffer actions; the big ring springs, with the help of the attenuation by multilayer oil films, being able to control the vibrations of the spindle in operation.
