Bakelite guiding wheel 1.Material: alumina ceramic 2.Purpose:used in wire drawing machine 3.Long working life

Bakelite guiding wheel  

Used for enameled wire or suitable-oriented silk thread, part of various types winding machines and textile machinery.The ceramic ring in the middle is made of precision ceramics, the polishing of groove can notch up Ra0.2 .Ceramic ring is matched with high-speed bearings, the baffle on the both sides can prevent enameled wire out of the slot, while the winding tension can maintain consistently.

 The items are served in the chemical fiber machinery before spinning and after spinninge quipment with A95, A99 alumina engineering ceramics and titanium oxide guide wire device and engineering plastics, including winding head -rabbit head, paper tube chuck, network wire nozzle, import filter sand and suction wire gun. 

 

The products are widely used in electrical, electronic, chemical, railways, textile machinery,chemical mechanical winding machine, wire and cable machinery, burners, fishery machinery, Tin Machine, wire drawing machine, construction, oil and aerospace industries in various fields.

Product Description

Specially formulated for wire drawing applications. This fine-grained zirconia ceramic

provides extreme Hardness, an exceptionally smooth wire drawing surface and

excellent corrosion resistance.

Hardness

Specially formulated, zirconia ceramic is the most man-made material for wear applications such as wire drawing capstans.

Corrosion Resistance

Specially formulated, zirconia ceramic is highly resistance to attack by corrosion problems(chemical contents used in processing of wire drawing).

The corrosion resistance fo zirconia ceramic is far superior to metal.

Surface Finish

The superior surface by high polish processing result in high quality of the drawn wire plus extended die life.

Providing excellent hardness, corrosion resistance, superior surface finish, ceramic capstans attained worldwide estimation in wire drawing industries field.
