extension springs Assembly

Product catalog summary

Overview: This document provides detailed specifications for various extension spring assemblies, including their dimensions, load capacities, fatigue life, and materials used. The document is structured into tables listing different spring models with their respective technical details.

Specifications:

Each spring model is identified by a unique number (e.g., SA242, SA243) and includes dimensions in millimeters (mm) for parameters A, B, and b.
The load capacity is given in Newtons and kilograms, with a specified fatigue life in cycles.
Spring specifications may not always conform to chart values when used in assemblies.

Materials:

Springs are primarily made of stainless steel.
Other components are made from mild steel, zinc-plated, and clear passivated materials.
Some assemblies include nylon molded bobbins and brackets secured to an aluminum base.

Key Data from Tables:

Spring models such as SA242 to SA271 are listed with varying dimensions and load capacities, with fatigue life ranging from 5,000 to 40,000 cycles.
Additional models like BBSR64 to BBSR23 are detailed with specific load capacities and fatigue life, indicating different end types (e.g., A, C, F).

Recommendations:

Ensure compatibility of spring specifications with assembly requirements, as deviations may occur.
Consider the fatigue life and load capacity when selecting springs for specific applications.
