About Lee Spring
About Lee Spring
Lee Spring Company was founded in 1918 by Robert Lee Johannsen in Brooklyn, New York, and has grown into a global manufacturer of mechanical springs serving engineers and procurement teams worldwide. The company is best known for its extensive catalog of stock compression, extension, and torsion springs that buyers have relied on for off-the-shelf sizing for decades.
Beyond its stock catalog, Lee Spring manufactures custom springs engineered to application-specific load, deflection, and material requirements, supporting industries from medical devices to industrial machinery. The company expanded its capabilities through acquisitions, including the 2022 purchase of Dayton Spring, broadening its custom and stock spring manufacturing capacity.
Lee Spring's long operating history and comprehensive catalog make it a common first stop for engineers sizing springs during design, since stock parts can often replace what would otherwise require a custom tooling order. ChatMRO indexes the Lee Spring catalog so buyers can search by spring type, wire diameter, or load specification to find matching parts.
