Ball Plunger ZC101 Series: Ball Plunger Model: ZC101 What it is A spring plunger (ball plunger) used for precision positioning in mechanical devices, molds, automated machinery, and related fields. Also known as positioning beads or positioning columns. How it works Installed inside screw threads. Preload is adjustable by controlling the screwin depth, enabling a defined locating force and repeatable positioning. Key attributes Function: provides repeatable locating and stopping positions in assemblies and fixtures. Compatibility: designed for screwthread mounting in compatible threads; please refer to the ZC101 series specifications for exact thread sizes. Size: modelbased; ZC101 is one option within the Ball Plunger series; exact dimensions vary by model. Material: material details are provided in the product datasheet for ZC101; refer to the datasheet for specific composition and hardness. Performance: offers reliable, repeatable positioning with adjustable preload to suit different fixture requirements and tolerances. Benefits Simple, compact solution for accurate positioning and indexing. Adjustable preload allows tuning for different materials, loads, and cycle requirements. Durable and maintenancefriendly, suitable for repetitive locating in tools and machinery. Use scenarios Mold tooling: locate inserts or guide pins with a defined stopping position to ensure repeatable cavity alignment. Automated machinery: provide repeatable workpiece indexing and alignment for fast, consistent cycles. Fixtures and jigs: set precise stop positions during assembly or testing sequences. Notes For exact size, thread compatibility, and material specification, consult the ZC101 product datasheet.
