Stainless Steel Spindle Chuck 2.5x025 Flange 23.5mm Height 43.9mm Ceramic Body

Stainless Steel Spindle Chuck 2.5x025 Flange 23.5mm Height 43.9mm Ceramic Body

This is an unbranded precision stainless steel spindle chuck sized 2.5x025, featuring a flanged stainless steel head assembly and a white ceramic body. The chuck uses a ball-lock retention mechanism below the flange and terminates in a black lower cap. It is designed for precision rotary or fixturing applications where accurate, repeatable spindle engagement is required.

Applications

Stainless steel spindle chucks of this style are used in precision machining, semiconductor wafer handling, and laboratory or industrial fixturing applications where cleanliness, dimensional accuracy, and corrosion resistance are required. The ceramic body construction is particularly common in semiconductor and clean-room environments, where non-conductive, chemically resistant materials are preferred to avoid contamination. The flanged mounting face allows secure, repeatable attachment to spindle housings or precision positioning stages. Ball-lock designs like this one provide quick tool-change capability while maintaining tight runout tolerances — a feature valued in automated or high-throughput precision assembly equipment. This style of chuck also sees use in optical fabrication, thin-film deposition tooling, and other precision substrate-handling systems.
