Agricultural Spring
We manufacture durable agricultural spring with wire diameters 2mm–18mm, outer diameters 15mm–200mm and customizable free height/length 50mm–2000mm, including compression, extension and torsion types. High-strength raw materials and heavy-duty anti-rust surface treatments extend the service life of each agricultural spring under dusty, humid field conditions.
Harsh Working Condition Adaptability
High mechanical strength
Thick high-strength spring steel withstands heavy loads and frequent impact during farm operations
Wear & rust resistant
Heavy-duty surface treatments including plastic coating and electrophoresis block corrosion from dust, rain and mud outdoors
Outstanding anti-fatigue performance
Constant vibration and cyclic loading during farming require long fatigue life to avoid frequent replacement
Stable outdoor performance
Reliable anti-rust coating maintains stable elasticity under long-term sun and rain exposure
Types & Material Options
Compression, extension and torsion types are all available. Raw materials: high carbon spring steel (65Mn/82B), alloy spring steel (60Si2Mn/55CrSi). Surface treatments focus on long-term anti-rust protection: plastic coating, electrophoresis, black oxide, zinc plating.

Application Fields
Mainly matched with tractors, harvesters, seeders, transplanters, garden machinery and agricultural transport vehicles.
Industry Customization Service for Farm Equipment
Baoding Zhongxin Spring Manufacturing Co., Ltd. accumulates rich industry experience in agricultural spring production. We fully understand load characteristics, working environments and usage frequency of all types of farm machinery to recommend optimal material and surface treatment schemes. Customization is supported via drawings, samples or complete farm machine model matching. Professional agricultural machinery elastic part design helps farm equipment manufacturers achieve longer service life and lower maintenance costs.
