RS PRO Steel Extension Spring 66.2 mm Free Length, 13 mm Outside Diameter, 1.2 mm Wire Diameter, 751-922

RS PRO 751-922 Steel Extension Spring is engineered for mechanical applications requiring strong and reliable extension force. Made from steel and manufactured in the United Kingdom, this extension spring has a free length of 66.2 mm and an outside diameter of 13 mm, with a wire diameter of 1.2 mm. It is designed to absorb and store potential energy efficiently, allowing connected components to return to their original position after extension.

The spring’s maximum extended length is 178.2 mm, with an initial tension force of 42.2 N and a spring rate of 0.32 N/mm. These specifications ensure consistent performance under heavy-duty operating conditions. The steel material offers excellent corrosion resistance, suitable for use in environments with moisture and humidity.

Attachment is facilitated by the closed loops at each end, allowing for secure connections using hooks or carabiners in industrial, manufacturing, mechanical, and HVAC applications. The spring complies with DIN 17223, RoHS, and BS 1408 CR3 standards, ensuring high quality and environmental compliance.

This extension spring is ideal for integrating into assemblies where reliable tension and energy storage are critical, such as machinery linkage, power transmission, and load balancing systems.

Constructed from high-strength steel for durability and corrosion resistance. Free length of 66.2 mm and maximum extended length of 178.2 mm provide flexible extension capabilities. Wire diameter of 1.2 mm supports heavy-duty tension loads.

Initial tension of 42.2 N ensures secure force before spring extension. Spring rate of 0.32 N/mm delivers consistent load response. Compliance with DIN 17223, RoHS, and BS 1408 CR3 standards for quality and safety. Designed with closed loops at both ends for easy installation.

Ideal for industrial, mechanical, manufacturing, and HVAC applications requiring durable tension springs. Explore more industrial fasteners and mechanical components within the Extension Springs category on EnvMart to find the perfect solutions for your applications.
