Ceramic Shaft Rod Harder Strength And Wear Resistance Alumina Zirconia Rods

As a Professional Advanced Technology Ceramic Manufacturers, Us Support To Customize Different Specifications Of Ceramic Components

Brief Introduction:
Shaft is a cylindrical object that runs between the bearings or the wheels or the gears, but there are also a few square ones.A shaft is a mechanical part that supports a rotating part and rotates with it to transmit motion, torque, or bending moment.It is generally round and rod-shaped with different diameters.The rotating parts of the machine are mounted on shafts.

Wear and hardness and abrasion:
The ceramic is better wear and abrasion resistant property than metal. The ceramic hardness (mohs)up to 9, HRA 80-90. Ceramic hardness is not second only to diamond, but far beyond the wear resistance of steel and stainless steel.

Part us manufacturer the rod sizes:

OuterDiameter (Inch)	Outer Diameter (mm)	Maximum Length
0.011	0.28	12in / 305mm
0.020	0.51	12in / 305mm
0.022	0.56	12in / 305mm
0.024	0.61	12in / 305mm
0.029	0.74	12in / 305mm

Dimension and tolerance:
·Diameter as small as 0.2mm， depends on length
·Length as long as 400mm, as short as 0.5mm
·Diameter tolerance we could make as fine as 0.001mm

The structural shape of the ceramic shaft rod:

Crank shafts, straight shafts, flexible shafts, solid shafts, hollow shafts, rigid shafts, flexible shafts (flexible shafts).

Precision of ceramic shaft rod:

Dimensional accuracy

1. The dimensional accuracy of ceramic shaft parts mainly refers to the diameter and length of the shaft dimensional accuracy.According to the requirements of use, the diameter of the main journal size accuracy is usually it6-it9 class, precision of the journal can reach IT5 class.

2. The surface roughness is different according to the precision degree of machinery, the running speed and the surface roughness requirements of shaft parts.Generally, the surface roughness Ra values of support journal are 0.63-0.16 microns.The surface roughness Ra values of mating journal are 2.5-0.63 microns.
