What is a belleville washer
When the need arises to keep bolted connections tight, a reliable compression device like the Belleville washer is a must.
What is a Belleville Washer?
A Belleville washer is a disc spring of conical shape. Its unique design and structure give the washer the characteristics and functionality of a spring. These disc springs are used across a variety of industries because they exert a uniform pressure that remains consistent. Where tension is lost due to thermal expansion or contraction, wear and tear of parts or compression, these devices can be particularly useful.
A Belleware Washer serves many functions such as:
- Bolted applications with heat expansion
- Flange connections
- Pre-assembled systems
- Inventory management
- High-speed press
- Bolted assemblies
Factors to consider when choosing your washer
When choosing your washer, there are specific parameters you need to take into consideration including Belleville washer torque, diameter, and finish.
- Torque – Torque is the force that is required to flatten the washer to ensure optimum clamping. Ideally, the torque of your washer should match your bolts to achieve a tight connection without compromising the washer.
- Diameter – The diameter of your Belleville washer is vital to its performance. It needs to be suited to the specific application to generate enough clamping force for a reliable connection. If it is too big, you will have less power than is required.
- Finish – Many washers provide the option of a standard finish, however, in cases where there will be fumes or solvents in the work environment, the manufacturer’s product applications engineer should be consulted to avoid compromising the connection.
