Audited Supplier Product Name:
Tungsten Steel Cylinder Liner with Precision Silicon Nitride Piston Shaft
Product Application: Gas sealing applications
The high hardness and wear resistance of the material are the requirements for the combined use of this product. Tungsten steel, as a super-hard metal, is widely applicable to core working components in precision mechanical industries. Silicon nitride, as a structural ceramic material, has even higher hardness than tungsten steel. Silicon nitride itself possesses lubricity and wear resistance, is crystalline, and exhibits oxidation resistance at high temperatures. Silicon nitride ceramics can withstand thermal shocks and, when heated to over 1000°C in air and rapidly cooled and reheated, will not shatter. Due to its excellent performance, silicon nitride ceramics are suitable for manufacturing bearings, turbine blades, mechanical seal piston shafts, piston rods, permanent molds, and other mechanical components.
The silicon nitride piston shaft is precisely matched with the tungsten steel first, second, and third-stage cylinders to meet the uniform requirements of tight to sliding fits. Each piston shaft and cylinder liner must be machined to size precision to ensure consistency. The assembly dimensions for the silicon nitride piston shaft require a size tolerance of 0, -0.002, concentricity, and total runout meeting 0.002. The three tungsten steel cylinders, processed from tungsten steel, have an inner hole tolerance of +0.004, 0, and requirements for cylindricity and concentricity at 0.002, satisfying the three-stage combination matching of the piston shaft.
