Silicon Carbide Wear-resistant Bushing/Liner
- [Introduction]: Silicon carbide bushing is a new high-tech wear-resistant material in the world.
Main feature:
(1) High hardness, with Rockwell hardness of 91 and Vickers hardness of 2115.
(2) Good wear resistance and long service life. Its wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high chromium cast iron.
(3) It has a wide range of usability and is applied to various wear-resistant industries. - [Size]:

- Advantages
- A complete set of custom assembly solutions can be provided.
- The density can reach 3.02-3.05 g/cm3, high density, high hardness, high wear resistance, and corrosion resistance.
- Short delivery time.
- Complete main structure can be customized with polyurethane and steel shell.
- Product Application
Silicon carbide bushing is widely used in mining, ore crushing, screening, and transportation of high-wear and high-corrosive fluids. It is very suitable for mechanical products with high precision and tightness requirements, such as high-pressure pumps, magnetic pumps, etc.
- 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.
