China Coil Winding Wire Roller Pulley Ceramic Wire Guide Pulley

Wire Roller Pulley Ceramic Wire Guide Pulley

is commonly used component when wire passing is required, it can be used in
coil winding machine, cable machine and the textile machinery as well.
The porcelain
ring is mounted on the bearing, Coil winding wire guide pulley(wire roller) will rotate by the thread and wire passing on the surface of the ring.
Thus the sliding friction has been converted to the static friction.
But at the start and stop, in order to overcome the inertia, there will be a partial
sliding friction. The surface Polish degree of the porcelain ring reaches Ra0.2;

The beating during rotation is under 0.15.
We select the 99% AL2O3 as the material with the hardness of HRA88 and the density of 3.85.

Description:
Wire groove:
Material: AL2O395%, hardness: HRA88.
Roughness: fine polishing above Ra0.2.

HARTAI TECHNOLOGY INDUSTRY Co., Ltd offers high quality ceramic wire guide pulley(ceramic roller) for Textile, Fiber and Wire Processing Machines. There is description about it as following:
Coil winding Ceramic wire guide pulleys (ceramic roller) is used on coil winding machine for enamel insulated wire or silk thread appropriate amount guiding, the China circle makes from precise ceramics, the surface smoothness that the China marks with a circle reaches Ra 0.2, moves up and down when rotating being smaller than 0.15, material selects and uses 99%'s Al2O3, hardness HRa 88, density 3.85.
