All zirconia ceramic bearing and bushing components we produced are well-engineered with long-term durability and reliability. Our complete manufacturing process from shaping to high precision machining allow us to maintain the high standard in dimensions, surface quality to meet customers' tough requirement.
Zirconia ceramic bearing and bushing components feature their superb wear resistance, excellent flextural strength, unmatched thermal isolation, light weight and low coefficient of thermal expansion to stainless steel. Due to these outstanding properties of zirconium oxide ceramic bushings, it's widely used as protection tube, ceramic bushings for pumps, ceramic housing for lambda sensor and so on.
Our facility offers a variety of customized solution for zirconia ceramic bushings, including different partial stabilizers, different geometries, different dimensions and different surface treatment. With our state-of-the-art and comprehensive in-housing precision equipment, we not only support high volume production, but also could support prototyping cases.
Moreover, we also manufacture other selection of advanced ceramic bushings, such as alumina ceramic tube, silicon carbide tube, silicon nitride tube, aluminum nitride ceramic tube. All these ceramic tubes can be machined at our site to achieve tight fitting relationship.
Raw material zirconium oxide, aluminum oxide, silicon nitride, silicon carbide
Dry pressing, hot pressing, ISO pressing, ceramic injection molding
round tube, square tube, rectangular tube, slotted tube, half tube, flanged tube
OD is range from 1 mm to 300 mm, length from 0.5mm to 800 mm
Fine grinding, Drilling, Laser cutting, CNC machining, lapping
The tolerance of OD can be ± 0.001 mm, ID ± 0.005 mm, length ± 0.10 mm
polishing with diamond - like surface, glazing, metallzing for ceramic to metal jointing
Free of cracks, foreign contamination, mirror surface better than Ra 0.1
1. Much higher density than most of technical and advanced ceramics, over than 6 g/cm3
2. Excellent wear and abrasive resistance, much higher 276 times than stainless steel
3. Low thermal conductivity, less than 3 W/m.k at room temperature, so it can couple with metal well
4. Exceptional high hardness, over than 1300 MPa for Vicker hardness, it leads to high wear resistance
5. Can withstand higher temperatures up to 2400° under vacuum or reduced atmospheres
6. Exceptional fracture toughness than almost advance ceramics, reaches up to 8 Mpa m1/2
7. Chemical inertness which can withstand most of acids and alkali, aging resistance and not rust forever
8. Resistance to molten metals and avoid any metal residual on surface due to an extraordinary melting point
9. Various complicated design production capability with tighten tolerance, precise dimensions
Remark: we have been supplying variety of customized zirconia ceramic tube per customers' specification,
real samples with low MOQ requirement.
