Silicon Carbide Roller
- [Introduction]: Silicon carbide rollers as the key part of roller kiln, its function is supporting and conveying calcined ceramic products under high temperature sintering process. High temperature bearing capacity, long-term use without bending deformation, service life is more than 10 times of alumina rollers.
- [Size]:
OD40*1000*6mm
OD50*3800*6.5mm
OD45*520*6mm
OD50*3000*7mm
Length can be manufactured up to 4000mm, with diameters and thickness according to your request.

- Advantages
- The straightness tolerance is accurate, up to 0.6‰-1‰.
- Length up to 5200mm.
- Good thermal stability, no fracture.
- We have good production technology and more than 50 sets of production equipment, which makes the delivery time short, and the normal output is more than 8000 pieces per month.
- Product Application
Silicon carbide roller is suitable for high-temperature firing zone of sanitary porcelain, daily ceramics, building porcelain, glass and magnetic materials in the roller kiln. It is also suitable for roller kiln for firing lithium battery anode and cathode materials and photovoltaic materials.
- Our Packing
The two packing methods we use are plywood box packing and solid wood packing, with the solid wood box requires a fumigation certificate. Depending on the various products, we will tailor the proper packaging box; Plastic foam measuring 2 cm to 3 cm thick is placed within the box and secured with row nails. To maintain the products safety during shipment, packing tape is typically used.
