Lee Spring supports assemblies where motion, force and space must stay predictable.

Springs are small parts with a large effect on uptime and product feel. This page organizes common buying contexts around the application evidence that matters most: working travel, installed height, cycle expectation, exposure, finish and reorder cadence.

Vertical grid

Five industrial contexts for spring and wire form requests.

Industrial equipment

Compression springs, torsion springs and wire retainers used in guards, latches, fixtures and small motion assemblies.

Fluid and valve systems

Stainless spring choices reviewed around corrosion exposure, sealing behavior, actuation force and service conditions.

Medical and device assemblies

Small spring features managed with cleaner documentation around material, finish, handling and repeatable dimensional requirements.

Electronics and controls

Contact springs, formed wire clips and compact biasing elements considered against tight spaces and consistent response.

Manufacturing MRO

Replacement springs identified through dimensions, load behavior, photos, samples and urgency so maintenance teams can keep assets moving.

Fit matrix

Application evidence changes the recommendation.

Application factor	Buyer should provide	Lee Spring review focus
Motion and load	Installed height, working travel, target load and return force.	Spring rate, stress margin, end condition and catalog fit.
Operating environment	Temperature, corrosion exposure, cleaning chemistry and contact surfaces.	Material, finish, fatigue risk and surface behavior.
Assembly space	Outside diameter, wire diameter, available stroke and mating hardware.	Envelope control, tolerance discussion and interference risk.
Supply pattern	Prototype quantity, reorder cadence, packaging preference and receiving needs.	Quote notes, label requirements, production handoff and repeat planning.

Industry RFQ

Prepare the request before opening the quote form.

A useful RFQ does not need to be long, but it should carry enough evidence to prevent guesswork. Include a drawing or photo if available, then add the operating load, the space around the spring, material exposure, annual quantity and whether the request is a new build or replacement.
