Symmetrical Crest-to-Crest springs cannot be installed upside down. For non-symmetrical custom configurations, correct orientation must be strictly maintained via housing keys.
Yes, pneumatic rams, tapered mandrels, and automated assembly sleeves are engineered to streamline high-speed production line integration without damaging the waves.
They provide accurate return forces for valve spools and relief mechanisms within a compact valve body block, saving space and weight.
Crest-to-Crest springs are inherently stacked in series. For parallel stacking (to increase force), nested wave springs should be selected rather than stacking separate loose springs.
A minimum clearance is required to absorb the radial expansion during compression. Typically, engineering guides recommend a 1% to 5% diameter clearance based on the specific wave design.
A pilot refers to the locating surface (either the shaft OD or the housing ID) that physically centers and stabilizes the wave spring during its stroke cycle.
They provide precise, low-force preloads in surgical tools, orthopedic instruments, and drug delivery devices where space is severely constrained and sterilization is required.
Their extreme weight savings, space-saving design, and ability to operate reliably under extreme temperature fluctuations using superalloys make them invaluable for aerospace valves and actuators.
Yes, they are ideal for preloading ball bearings. Eliminating axial play reduces bearing noise, dampens vibrations, and prevents ball skidding, which drastically extends bearing life.
They exert a highly uniform, continuous axial pressure against the seal faces, compensating for face wear, thermal expansion, and minor shaft misalignments over a long service life.
They are widely used in automatic transmissions, steering columns, quick disconnect connectors, valve trains, and dual-clutch assemblies to maintain preload and take up axial play.
They are manually or automatedly slipped directly into the housing bore or over the shaft onto the seating surface. Ensure no twisting or binding occurs during the placement process.
Hardness is typically verified using Rockwell or Vickers microhardness testing on a cross-section of the wire to ensure compliance with material specifications.
Yes, PTFE coatings can be applied to provide low-friction properties, eliminate noise/squeaking, and provide additional chemical resistance.
AISI 316 stainless steel is widely preferred due to its superior non-reactive properties, easy sanitization, and compliance with food and drug contact regulations.
Carbon steel is the most economical. Stainless steel adds a moderate premium, while superalloys like Inconel, Elgiloy, and Hastelloy dramatically increase costs due to material and processing complexity.
Shot-peening introduces beneficial compressive residual stresses on the surface, which significantly enhances fatigue life across carbon steel, stainless steel, and superalloys.
Oil-tempered wire is pre-heat-treated to a uniform hardness and high tensile strength, providing superior structural uniformity across large wire profiles.
Passivation removes free iron from the surface using an acid solution, creating a passive chromium-oxide protective layer that prevents rust and environmental corrosion.
