Custom Compression, Torsion, & Extension Springs for OEM EQuipment Manufacturers
When a component fails in the field, it can lead to downtime, service disruptions, and project delays. Many of those failures trace back to small mechanical components that lose force, wear out, or fail under repeated use.
That’s where we fit.
Wermke Spring manufactures custom OEM springs and precision wire forms built directly to your specifications, backed by ISO 9001:2015 quality management systems. We supply compression springs, torsion springs, extension springs, and formed wire components used in commercial equipment across agriculture, mining, construction, and industrial machinery.
We build to your drawings. We manufacture to your specifications. We deliver repeatable results. Contact our spring manufacturing team to learn more or request a quote for your project today.
Engineered Custom Springs for Heavy Equipment Applications
Heavy equipment operates in demanding environments where components must perform under continuous use, extreme loads, constant vibration, and exposure to dirt, moisture, and chemicals.

Our custom springs for heavy equipment are manufactured to:
- Maintain force across repeated load cycles
- Resist fatigue and mechanical wear
- Perform in outdoor and variable environments
- Hold tight tolerances across production runs
We support a wide range of material sizes, including larger-diameter spring wire for heavy-duty commercial equipment applications.
Common applications include:
- Suspension systems in construction and off road vehicles
- Hydraulic and mechanical control systems
- Bucket, blade, and attachment mechanisms
- Brake and clutch assemblies
- Vibration isolation and shock absorption systems
Each of these applications requires precision engineered springs that can deliver consistent performance over long service cycles.
Types of Heavy Equipment Springs
Different types of springs are used depending on the application and load requirements.
Compression Springs
Compression springs are commonly used in load bearing and shock absorbing applications. They are designed to resist compressive forces and return to their original shape after deflection.
Typical uses include:
- Suspension and load support systems
- Shock absorption in high impact operations
- Hydraulic valve assemblies
Extension Springs
Extension springs provide resistance under tension and are used to return components to their original position.
Applications include:
- Linkage systems
- Return mechanisms in controls
- Tensioning systems for moving components
Torsion Springs
Torsion springs generate rotational force and are used in pivoting or hinged components.
Common uses include:
- Equipment doors and access panels
- Lever and control systems
- Rotational positioning mechanisms
Custom Wire Forms
Precision-formed wire components for retention, positioning, and structural support across virtually any heavy equipment assembly.
Common Applications include:
- Retention clips
- Latch mechanisms
- Cable routing
- Positioning components within assemblies.

Custom Spring Applications by Industry
Agriculture Equipment Springs
We manufacture custom springs for agricultural OEM manufacturers, supporting machinery such as planters, combines, sprayers, and harvesting systems. Agricultural equipment depends on consistent performance across long operating cycles. Our components are built to support that reliability.
Applications include mechanical linkages and control systems, tensioning and positioning components, retention clips and latch mechanisms, and assemblies requiring consistent force and repeatable motion.
Mining Equipment Springs
Mining operations depend on equipment that performs continuously. Component reliability directly supports uptime. Wermke produces heavy-duty springs for mining equipment where durability and long-term performance are critical.
Typical applications include retention and securing mechanisms, mechanical return and assist functions, components requiring consistent force under load, and wire forms used in structural or support roles.
Construction Equipment Springs
We supply custom springs for construction equipment manufacturers, supporting machines operating across varied job site conditions. These systems require components that perform reliably over thousands of cycles in changing environments.
Common applications include control linkages and actuation systems, safety latching and locking mechanisms, mechanical support components within assemblies, and custom wire forms for positioning and retention.
Springs for Other OEM & Industrial Equipment
In addition to agriculture, mining, and construction, Wermke Spring manufactures custom OEM springs and wire forms for a wide range of commercial and industrial equipment. In many cases, the end application varies. The requirement does not. The part must perform as specified.
Applications across other commercial and industrial equipment often include access panels and service doors, operator controls and mechanical linkages, safety mechanisms and locking assemblies, hydraulic and pneumatic system support components, and vibration isolation and preload components.
Engineering Considerations for Heavy Equipment Springs
Designing springs for heavy equipment requires careful attention to mechanical and environmental factors.
High Load and Stress Requirements: Heavy equipment springs must withstand significant forces without yielding or permanent deformation. Proper stress calculations and material selection are critical from the first prototype run.
Fatigue Resistance: Repeated loading cycles can lead to fatigue failure if not properly addressed. Springs must be designed for long cycle life using appropriate materials and manufacturing processes.
Environmental Durability: Exposure to dirt, moisture, chemicals, and temperature extremes requires corrosion-resistant materials and protective coatings.
Learn more about our custom spring material and coating capabilities.
Shock and Impact Resistance: Heavy equipment operates in environments with high impact loads. Springs must absorb and dissipate energy without failure, even under unpredictable load spikes.
Dimensional Precision: Accurate spring rate and load characteristics are essential for ensuring reliable equipment performance and system integration.
Materials & capabilities for Custom Spring Manufacturing
We manufacture custom springs and wire forms using a wide range of materials based on your specifications, including high-carbon spring steel, oil-tempered wire, chrome silicon, alloy steel, stainless steel, music wire, phosphor bronze, beryllium copper, and brass.
All components undergo controlled stress-relief processes after forming to ensure dimensional stability and long-term performance. When required, we coordinate plating, coating, and finishing through qualified partners so parts arrive ready for use. Learn more about spring materials and selecting the right option.
Frequently Asked Questions
What materials are best for heavy equipment springs? Common materials include oil-tempered wire, chrome silicon, and alloy steels, which provide high strength and fatigue resistance. Depending on load requirements and environmental exposure, stainless steel can also be a strong option. Learn more about spring materials.
How do you improve spring durability in harsh environments? Durability can be improved through material selection, heat treatment, and protective coatings such as zinc plating or powder coating.
Can heavy equipment springs be custom designed? Yes. Springs can be engineered to meet exact specifications for load, size, and environmental conditions. Wermke Spring works directly from your drawings with no mandatory redesign of existing proven designs.
Why is fatigue life important in heavy equipment applications? Heavy equipment operates continuously under load. Springs must withstand repeated stress cycles without failure to avoid downtime and unplanned maintenance costs.
What is your minimum order quantity? There are no rigid minimums. Wermke Spring supports prototype runs, short-batch production, and ongoing scheduled manufacturing aligned with your workflow.
