A Belleville washer, also known as a coned-disc spring, [1] conical spring washer, [2] disc spring, Belleville spring or cupped spring washer, is a conical shell which can be loaded along its axis either statically or dynamically.
cb manufactures belleville washer, disc springs, disc spring stacks and slotted disc springs. Special springs, wave springs, ball bearing disc springs and conical spring washers are also part of our portfolio.
A Belleville washer or disc spring is a conical-shaped spring with an open center. It is shaped much like a washer and is typically smaller than a coiled spring. Because Belleville washers can bear a much larger load relative to its deflection rate than a coiled spring, they are ideal for cushioning heavy loads with short motion.
In both mass production and custom design, we employ the standard calculations of DIN 2092 to create a disc spring or washer with predictable deflection for a given load. Our disc springs and washers may be used singly or stacked in series, in parallel, or in parallel sets in series.
Belleville disc springs are used everywhere from the automotive, food processing, and chemical industries and found in applications from boilers and industrial furnaces to superconductors and satellites. They are commonly used in applications requiring high spring force and small deflections.
Belleville disc springs are found in many components used in oil refining, such as pipelines, pipe supports, pumps, valves, and actuators. Properly designed and installed, BelleFlex® flange bolting can reduce flange leakage in pipelines, and increase the life of gasketed … →.
