Stacked-Stage Cartridge Assembly with Mechanical Shaft Seal Cartridge and Stepped Extension

We manufacture this mechanical shaft seal cartridge to keep interfaces aligned during assembly. For each mechanical shaft seal cartridge we lock in your required tolerances, surface finish, and material grade as controlled routing parameters. The current CAD file with revision index remains the single reference, with any later adjustments driven only from your updated release. At our production plant in Changshu, an ISO 9001 line supports precision machining for automation and automotive parts. Established in 2017, the facility offers in-house anodizing, black oxide coating, and chemical plating, supplying aerospace, medical equipment, and military sectors. Quoted cost is based on order quantity and finish.
