According to the materials performance，stretch bolster is adopted in the spindle for cotton and chemical fibers；In TFO spindle for wool spinning, rolling bearings are adopted on upside and underside to support，and in TFO spindle for real silk, on its upside it is supported by the rolling bearing and a sliding bearing structure is adopted on its nether. Rotating parts of the spindle have been precision dynamic balance test, parts yarn passed are made of abrasion proof ceramics and advanced plasma spray painting surface A kind of tension ball is used in spindle for chemical fibers and silk to control the tensile force. And in the spindle for cotton textile TFO spindle, it is controlled by tension capsule.
Special designed spindle root made the chemical fiber spindle and short fiber spindle exchangeable.
