A pressure spring is a mechanical component that applies controlled force through compression to maintain tension, alignment, or pressure in drive roll assemblies and similar machinery.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Free Length | 20-200 mm | |
| Spring Rate | 5-200 N/mm | |
| Wire Diameter | 1.0-10.0 mm | |
| Outer Diameter | 10-100 mm | |
| Maximum Compression | 50-80% of free length | |
| Operating Temperature | -20°C to 120°C | |
| Load At Working Height | 50-5000 N |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is used in the following industrial products
Mechanical assembly that grips and advances welding wire through the wire feeder system
A mechanical device that inhibits motion by absorbing energy from a moving system, specifically used to stop or hold the rotor of an indexing motor.
A safety valve in Common Rail fuel injection systems that prevents excessive pressure buildup by diverting excess fuel back to the tank.
A practical evidence checklist for RFQ preparation and supplier evaluation.

Manufacturer profiles associated with Pressure Spring.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
The pressure spring maintains consistent force between rollers to ensure proper material feeding, tension control, and compensation for wear or thermal expansion.
Consider required force (spring rate), operating space (dimensions), material compatibility, environmental conditions, and compliance with industry standards like ISO 10243.
Fatigue failure from cyclic loading, corrosion in harsh environments, permanent set from over-compression, and loss of spring rate due to material degradation.
