Product Description

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.
