Industrial Torsion Spring
We produce premium industrial torsion spring with high-quality spring steel wire through precision coiling. The wire diameter ranges from 0.5mm to 6.0mm, outer diameter from 5mm to 100mm. Custom rotation directions including clockwise, counterclockwise and bidirectional are available to match diverse working conditions.
Product Features
Stable torque:
Precise coiling and heat treatment guarantee uniform torque output within the working stroke, delivering consistent rebound force for every industrial torsion spring.
Outstanding fatigue resistance:
Raw materials include high carbon steel such as 65Mn & 82B, and alloy spring steel 60Si2Mn. Strict quenching and tempering processes extend service life under repeated torsion.
Customizable specifications:
Wire diameter, outer diameter, coil count and torsion arm angles can be adjusted according to installation space and load requirements.
Diverse surface treatments:
Natural finish, black oxide, zinc plating, nickel plating and plastic coating are optional to meet anti-rust and appearance demands in different environments.
Application Fields
Widely adopted for industrial doors, automobile seats, hardware fixtures, electrical switches, mechanical equipment and agricultural machinery that require torsional reset or torque transmission.
