To find the load at any working length, when free length and rate are given, use the formula: P = R x F where P is the load in lbs.; R is the rate in lbs. per inch; F is the deflection from free length. Example: (Lee Stock Spring Catalog #LC-032C-8) — Given a free length of .750” and a

Standard Spring Dimension Tolerances for Custom and Stock

At Acxess Spring we aim to manufacture your custom springs with precision but there are certain standard industry tolerances that must be taken into account. Sometimes, a dimension may be off by a few thousandths of an inch, or the force it exerts may be off as well as the travel due to wire density. This usually isn’t a problem, one dimension will make up for the other and your spring will

Compression Springs - General Considerations

A tolerance of +/- 10% is the standard. Anything smaller than this must take into account the factors that influence the load (the spring diameter, feed, free length, and wire size variation). Generally speaking, the feed and wire size vary negligibly. Diameter and length variation are what primarily control variation on

Standard Spring Rate Tolerance - The Spring Store

Example A.) You find a standard spring which has a spring rate of 10 pounds of force per inch so once you calculate the tolerance, you will see that the actual rate of force per inch of this spring could range in between 9 pounds of force per inch and 11 pounds of force per inch.

Free Length of Spring - Quality Spring, Affordable Prices

The free length of your spring is the length it has right when it comes off the machine. It is the length without those loads or forces. If a compression spring’s free length is too long in proportion to its diameter, it is going to bend/buckle. This is referred to as the Slenderness Ratio.

Tolerancing helical springs - Machine Design

Most spring makers change free length to boost load height and leave rate unchanged. Knowing this, designers should always allow a generous tolerance on free length or, better yet, make free length

Free Height: The height at which a wave spring is measured in its free state. Work Height: The designed height at which a desired force/load is delivered. It is also important to note - the free height of a wave spring is typically a reference dimension. Wave springs are normally designed to provide a specific tolerance/load at a given work height.

Tolerances - G&O Springs

Note: We do not normally recommend tolerancing free length, however ± 0,127mm (.005″) can be easily achieved. All springs should be scragged (in the case of a compression spring; compressed to solid length) before any load verification to ensure that any relevant prestressing has been carried out.
