Product Description

Brief introduction:
Ceramic roller is a most important part of glass tempering furnace, it is used to transport the glass moving to and fro inside the heating chamber. The quality of the ceramic roller directly affects the quality of tempered glass. If the quality of ceramic roller is not good, there would be some marks/pits, etc, especially for the automotive glass.
We only sell and make top quality ceramic roller, many glass processing factories choose our ceramic rollers for their glass tempering furnace/machine
For glass tempering furnace, normally, there are three types for the ceramic roller: solid type, hollow type, spiral type. The hollow type and spiral type is mainly used for automotive glass processing factory, which could reduce the white line at the middle of glass surface.
But now, in order to get the highest quality for automotive glass, most factory use ceramic fiber sleeves onto the ceramic roller, this ceramic sleeves could reduce the marks, white line greatly.
Advantages:
1. Raw material with high purity, excellent chemical and physical properties
 2. Good surface smoothness, not easy to scratch glass
 3. High density without bubbles
 4. Very High Compressive Strength, Flexural Strength & Impact Strength at high temperature.
 5. Good wear resistance
 6. Small radial beat (run)
 7. Very low thermal expansion coefficient
 8. Strong thermal shock stability
 9. High precision in size
 10. No deformation under high temperature
 11. Long service life, The reliable axle neck joint technology(anti-loose technology)
 12. No pollution to glass
 13. High economic efficiency, can reduce the overall cost of belt conveyer, reduce maintenance working hours
