Description
Product Overview
The HARFINGTON ball point spring plunger set is engineered for high‑precision applications where reliable positioning is essential. Crafted from 304 stainless steel, each plunger offers excellent corrosion resistance, heat tolerance, and structural integrity, ensuring a long service life even in demanding environments. The plunger dimensions—12 mm body diameter, 16 mm body length, and an overall length of 19.9 mm—provide a compact profile that fits seamlessly into tight mechanical assemblies.
Precision casting and polishing processes give the plunger a surface roughness of Ra 3.2, reducing friction and wear during repeated cycles. The elastic force rating of 40 N delivers consistent pressure, allowing the plunger to securely latch components without slippage. The no‑step design eliminates positioning gaps, granting users the ability to fine‑tune placement quickly and accurately, which is especially valuable in high‑speed automation settings.
Beyond its mechanical advantages, the plunger’s stainless‑steel composition ensures that it will not rust or degrade when exposed to moisture or chemicals commonly found in industrial workshops. This makes the HARFINGTON plunger a dependable choice for both indoor and outdoor applications, ranging from furniture hardware to heavy‑duty tooling fixtures.
Each package includes six identical plungers, providing a cost‑effective solution for projects that require multiple points of contact or replacement parts. The set is ready for immediate installation, with no additional components needed, simplifying inventory management for manufacturers and repair technicians alike.
Usage
These spring plungers excel in a variety of settings. In furniture manufacturing, they serve as discreet latch mechanisms for cabinet doors and drawer fronts, delivering a smooth, silent closing action that enhances the user experience. Their compact size allows them to be concealed within thin panel edges, preserving the aesthetic integrity of the piece.
In the realm of mechanical tooling, the plungers act as precise positioning aids for jigs, fixtures, and workholding devices. The 40 N spring force ensures that workpieces remain firmly seated during machining operations, reducing vibration and improving dimensional accuracy. This reliability is critical for CNC machining centers, where repeatability directly impacts product quality.
Automation engineers also benefit from the plunger’s quick‑release capability. The step‑free design enables rapid adjustments of robotic end‑effectors or conveyor‑mounted components, minimizing downtime during changeovers. Because the plungers are made from stainless steel, they can withstand the lubricants and cleaning agents typical in automated production lines without compromising performance.
