Black HRA 88 Coil Winder Wire Guide Pulley Wheels With Bearings
Wire guide pulleys (ceramic pulleys)
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...Two nylon side walls have been
put to the both side of the ceramic ring and the bearing, coil winding wire guide pulley
(wire roller) combines one wire roller Cable pulley wheels, wire cable pulley, flanged
cable pulley, plastic cable pulley, nylon cable pulley.
1, Wire groove:
Material: AL2O395%, hardness: HRA88.
Roughness: fine polishing above Ra0.2.
2, Original bearing from Japan
3, POM plastic sheeting.
