How Can Acxess Spring Simplify Your Spring Selection Process?

Finding the right spring for your project can be a real headache. With so many sizes, materials, and specifications out there, it's easy to feel overwhelmed. That's where Acxess Spring comes in. We've created a user-friendly part number system that takes the guesswork out of the equation. By breaking down each spring's dimensions and attributes into a simple numerical code, you can quickly pinpoint exactly what you need. In this guide, we'll walk you through how to decode Acxess Spring’s part numbers and make the most of our online tools to streamline your spring selection process.

1. Introduction to Acxess Spring's Part Number System

Acxess Spring LogoAcxess Spring Logo

Acxess Spring's part number system is designed to encapsulate essential spring dimensions and characteristics within a structured format. This approach streamlines the ordering process and ensures clear communication between customers and the manufacturer. By embedding all critical spring specifications into the part number, users can quickly identify springs that meet their exact requirements, reducing the time spent on product selection and minimizing errors in the ordering process.

2. Structure of the Part Number

Each part number is a sequence of alphanumeric codes, with each segment representing a specific attribute of the spring. The general format is as follows:

[Stock or Custom][Type][Wire Diameter]-[Outer Diameter]-[Total Coils]-[Material Type]-[Free Length]-[End Type]-[Finish]-[Unit of Measure]

Structure of the Part NumberStructure of the Part Number
  • P: Denotes ‘Stock Part Number'
  • A: Denotes ‘Custom Part Number’
  • [Type]: Indicates the spring type (e.g., C for Compression, E for Extension, T for Torsion, CC for Conical Compression)
  • [Wire Diameter]: Specifies the wire diameter
  • [Outer Diameter]: Specifies the outer diameter of the spring
  • [Total Coils]: Indicates the total number of coils
  • [Material Type]: Denotes the material used (e.g., MW for Music Wire, SST for Stainless Steel)
  • [Free Length]: Specifies the free length of a compression spring
  • [End Type]: Indicates the type of ends (e.g., C for Closed & Squared Ends, CG for Closed & Ground Ends)
  • [Finish]: Denotes the finish or coating (e.g., N for None, Z for Zinc)
  • [Unit of Measure]: Specifies the measurement unit (e.g., IN for inches, MM for millimeters)

This structured format allows for a comprehensive description of the spring's physical and material properties, facilitating accurate identification and selection.

3. Detailed Breakdown by Spring Type

c. Torsion Springs

Torsion springs are helical springs designed to exert a rotary or torque force when twisted around their axis. They are often used in applications that require a rotational force, such as in clothespins, garage doors, and vehicle suspensions. The spring arms rotate in angular deflection to store and release energy, providing a consistent torque to resist or apply pressure in a rotational motion. The part number format for torsion springs is:

PT[Wire Diameter]-[Outer Diameter]-[Total Coils]-[Material Type]-[Wind direction]- [Leg Length 1 and 2]-[Finish]-[Unit of Measure]


Example:


PT020-179-7000-MW-RH-0750-N-IN
