Belleville washers deliver big power in tight spaces

Belleville washers from Lee Spring are an excellent solution when an application requires high loads in a confined space. Compared to coil springs, Belleville washers conical configuration allows them to support high loads with relatively minimal deflection and solid heights.

Belleville washers are often used to address vibration, thermal expansion, relaxation, and bolt slippage issues.

Although Belleville washers can be used individually, they are generally grouped in various positions such as cylinder or column; for example, all aligned parallel, alternately opposite, or a combination of the two alternately placed face to face. Thus a single Belleville washer has a specific load at a given deflection; two washers placed in parallel will support twice the load of one at the same deflection; three, triple and so on.

Optionally, two washers placed in series will provide twice the deflection of one at the same load; three, triple, etc. Therefore, various series-parallel combinations can provide a wide variety of load and deflection results. Lee Spring offers a wide variety of ready-to-ship in stock Belleville washers ready for immediate delivery.
