Before the advent of high pressure compression springs, customers in need of higher spring rates would buy larger, bulkier compression springs. The introduction of high pressure springs means springs with smaller diameters can be used for the same job, providing improved support in small spaces.
High pressure compression springs are designed to provide high resistant forces with a relatively slender diameter spring. A standard spring can only support a certain amount of weight and would need a wider profile to take heavier loads, but a high pressure compression spring is fortified to achieve a higher spring rate (the spring rate refers to how many pounds a spring can be compressed to per inch). This means you can pile on much more weight for the diameter, in comparison to standard compression springs.
High pressure compression springs are used in applications with small spaces that require firm, but not rigid, slender springs, such as in switches, ball plungers, safety relief valves, quick change tools and vice clamps.
Using a high pressure compression spring, rather than a standard compression spring, in these instances will mean your spring lasts longer as it can withstand heavy loads – saving you money on maintenance.
High pressure compression springs from Lee Spring are made from passivated and shotpeened Stainless Steel, which provides a balance of corrosion resistance, high strength, and toughness – meaning your springs will last even longer, whatever the conditions. They range in size, fitting holes as small as 1/8” to 1” so you can achieve just as much strength and spring rate as a much larger and heavier spring, but in tighter spaces.
If you’re looking to take the load off and need small yet strong springs that will stand the test of time and not cost you the earth, try one of Lee Spring’s stock high pressure compression springs, or opt for high pressure features with our custom spring design service.
