Product Specification

Heavy Duty Compression Spring | 0.2-20mm Steel for Machinery

Product Description

Our Heavy Duty Compression Spring is engineered for superior load-bearing capacity and resilience in high-pressure environments. As a critical component in industrial machinery, these helical springs are designed to resist compressive forces and return to their original height with precision. We utilize premium-grade materials, including high-tensile carbon steel and specialized alloy wires, to manufacture springs that withstand rigorous mechanical cycling.

With a versatile wire diameter range of 0.2mm to 20mm, our compression springs are suitable for everything from delicate switch mechanisms to heavy-duty mining equipment. Every unit undergoes precision grinding and shot-peening to enhance fatigue resistance, ensuring an extended service life even under continuous heavy loads. Whether you require standard cylindrical profiles or specialized conical designs, our springs provide the durability and stability required for modern industrial manufacturing.

Features

• High Load Capacity: Engineered to handle significant compressive stress without permanent deformation.

• Extended Service Life: Advanced heat treatment and surface finishing processes minimize fatigue and wear.

• Precision Manufacturing: CNC coiling ensures tight tolerances for spring rate, free height, and outer diameter.

• Versatile Material Range: Available in oil-tempered steel, music wire, and stainless steel to suit various environmental conditions.

• Custom End Configurations: Options for closed and ground ends to ensure squareness and stable force distribution.

Technical Parameters

Applications

Our heavy-duty compression springs are the "backbone" of numerous industrial sectors:

• Industrial Machinery: Used in press machines, conveyors, and heavy-duty stamping equipment to absorb shock and provide return force.

• Automotive Industry: Essential for suspension systems, valve trains, and clutch assemblies where reliability is paramount.

• Valves & Pumps: Provides the necessary tension for fluid control valves and high-pressure hydraulic pumps.

• Aerospace & Defense: High-precision springs for landing gear, seating mechanisms, and specialized flight controls.

• Construction & Mining: Integrated into heavy-duty drilling rigs, vibrating screens, and structural dampers.

FAQ

Q: How do you ensure the spring doesn't lose height over time?

A: We perform a "set removal" or "presetting" process where the spring is compressed to its solid height multiple times during manufacturing to ensure it maintains its free height during use.

Q: Can you manufacture springs for high-temperature applications?

A: Yes, we use high-temperature alloys like Inconel or specialized stainless steel to ensure performance in environments exceeding 250°C.

Q: What is the minimum order quantity (MOQ)?

A: We support both small-batch prototyping and high-volume production. Please contact us with your specific requirements for a tailored quote.

Q: What surface treatment is best for outdoor use?

A: For heavy-duty outdoor machinery, we typically recommend galvanization or high-durability powder coating to maximize the extended service life.
