RS PRO Steel Extension Spring 75.4 mm Free Length x 11 mm OD, 29.6 N Initial Tension 751-887

RS PRO 751-887 Steel Extension Spring is a precision-engineered mechanical component designed for applications that require tension and controlled extension. Made of durable carbon steel material, this spring exhibits high tensile strength and excellent fatigue resistance essential for industrial and mechanical assemblies.

The spring's free length is 75.4 mm with an outside diameter of 11 mm and a wire diameter of 1 mm, making it suitable for compact installations while maintaining robust performance.

It features an initial tension of 29.6 Newtons and a spring rate of 0.17 N/mm, capable of providing reliable force resistance and returning to original length after extension up to a maximum length of 224.4 mm. This performance makes it ideal for use in trampolines, garage doors, and various commercial machinery that require a stable and durable extension spring.

Both ends of the spring have closed loops which simplify attachment to hooks or clips, facilitating quick installation and maintenance.

Manufactured in the United Kingdom, it complies with relevant RoHS directives and BS 1408 CR3 and DIN 17223 engineering standards, verifying material safety and mechanical properties.

Manufactured from high-tensile carbon steel for heavy-duty use. Free length of 75.4 mm ensures compact size in relaxed state. Has an outside diameter of 11 mm for stable mounting. Wire diameter measures 1 mm for optimal strength and flexibility.

Initial tension of 29.6 N provides necessary preload resistance. Maximum extended length is 224.4 mm allowing substantial elongation. Spring rate at 0.17 N/mm balances extension and force absorption. Compliant with RoHS, BS 1408 CR3, and DIN 17223 standards for quality assurance.

Features closed loops at both ends for easy attachment and installation. Suitable for industrial, mechanical, commercial, and agricultural applications.
