Industrial Tension Springs
We manufacture reliable industrial tension springs with wire diameters from 1mm to 16mm, outer diameters 10mm–150mm and customizable free length 50mm–2000mm, delivering stable industrial-grade performance for long-cycle mechanical operation. Optimized hook structure and anti-rust treatment extend the service life of every industrial tension springs.
Industrial-Grade Advantages
Stable mechanical strength
High-carbon steel (65Mn / 82B) and alloy spring steel (60Si2Mn / 55CrSi) provide high tensile strength and bearing capacity.
Excellent anti-fatigue performance
Complete heat treatment and surface strengthening resist fatigue failure under continuous industrial operation.
Durable end fittings
Industrial-grade hooks such as round hooks, long hooks, flat hooks, lifting rings and German hooks offer firm connection and anti-breakage performance.
Strong environmental adaptability
Surface treatments including black oxide, zinc plating, plastic coating and electrophoresis satisfy anti-rust demands of diverse industrial environments.
Material Selection
Carbon spring steel, alloy spring steel and stainless steel are available for selection based on load, working environment and cost budget to achieve optimal matching schemes.
Application Fields
Mainly used for mechanical equipment, automobile manufacturing, hardware tools, elevator fittings, agricultural machinery and industrial automation equipment.
