Jergens Spring Loaded Devices

Product catalog summary

Overview: The document provides comprehensive details on various spring-loaded devices, focusing on plungers. It covers specifications, materials, and design features that enhance performance and longevity.

Spring Plungers: Manufactured from case-hardened steel, these plungers are noted for their durability, accurate end forces, and ease of installation. Key features include improved contact points, longer springs for extended life, better alignment, and resistance to contamination.

Ball Plungers: These devices ensure precise spring pressure control and feature longer spring life due to minimized lining pin head thickness. They maintain uniform ball projection through controlled crimping pressure.

Specifications: The document lists specifications for inch and metric sizes, including thread sizes, forces, and material compositions. It advises countersinking tapped holes for easier insertion of spring plungers with locking elements.

Materials and Construction: Plungers are made from low carbon steel, black oxide, or 303-stainless steel, with tips from steel, stainless steel, or Delrin. The Solid Drive Plunger design eliminates the need for a set screw, enhancing reliability.

Additional Features: 3D solid models are available in multiple formats, and the products adhere to TCMA dimensional standards. Special requests can be made through a Plunger Quote Request worksheet.

Procedures and Recommendations: For easy insertion, countersink the tapped hole larger than the plunger's major diameter. Use a Jergens Plunger Wrench to avoid damage during insertion.

Materials and Standards: Body materials include low carbon steel and 303 stainless steel, with finishes like black oxide. Ball materials are typically stainless steel, and spring materials are stainless, 17-7 PH.

Retractable Plungers: These include pull ring and L handle styles, designed for limited space applications. They feature a slight taper for easy alignment and locking mechanisms for secure positioning.

Spring Locating Pins: Used for fixturing small parts, these pins are available in materials like aluminum, steel, and stainless steel. They maintain constant pressure and are economical and easy to handle.

Spring Stops: Features include adjustable plunger travel, angled mounting slots, and material specifications like zinc aluminum alloy bodies. End force ratings and dimensional data are provided.

Installation and Application: The document includes formulas and tools for determining mounting hole locations and adjusting spring pin tension, with application ideas for positioning and holding various part profiles.
