Product Description
Knob Plunger Positioning Bushing Introduction
● Product Introduction
VCN119.1 Liner Bushing is a matching positioning bushing specially designed for Ball Lock Pins. It is made of carbon steel with black oxide anti-rust treatment. Precisely machined bore features primary and secondary inner diameter for accurate fit with corresponding ball lock pins. Normally press-fitted onto fixture base plates. Working together with ball lock pins, it enables quick insertion & removal positioning, improves positioning accuracy and protects mounting holes of base plate from abrasion caused by frequent plugging.
● Structural Features
Customized for Ball Lock Pin MatchingPrecision stepped inner bore matches corresponding ball lock pins, ensuring reliable ball engagement, smooth insertion and firm locking without clearance.
Carbon Steel with Black Oxide FinishHigh mechanical strength and impact resistance; black oxide coating provides anti-rust and anti-oxidation performance for continuous cyclic operation.
Tight Precision ToleranceStrict dimensional tolerance on inner bore guarantees stable repeat positioning accuracy and minimal fitting clearance.
Multiple thickness optionsVarious thickness selections for each ID size, compatible with different fixture base plate thicknesses for flexible assembly.
Protection for fixture base platePrevent direct friction and impact on base plate holes, avoid hole deformation, extend jig service life and reduce maintenance cost.
● Typical Applications
Welding Fixtures & Assembly ToolingsAutomotive welding jigs and component assembly fixtures for fast workpiece positioning with ball lock pins.
Inspection Gauges & Testing ToolingsMulti-station testing fixtures for dimensional inspection, maintain consistent repeat measurement accuracy.
Quick-lock Mechanism for MoldsFast positioning for simple molds and movable mold inserts, tool-free locking with ball lock pins.
Detachable Modules of Automation EquipmentPositioning for exchangeable modules and worktables to enable quick module replacement.
Sheet Metal & Aluminum Profile FixturesPrevent hole enlargement and abrasion on thin aluminum and sheet metal mounting plates.
