Industries We Serve
Our team at BelleFlex® has decades of experience in designing and manufacturing Belleville solutions for markets worldwide and in outer space – our Bellevilles are even used on the International Space Station.
Our Bellevilles, properly installed, promote long life for your equipment under the most difficult and challenging circumstances.
We supply Bellevilles that meet the needs of many markets, including Bellevilles for corrosive environments, high loads, or extreme temperatures.
Materials like H13 Tool Steel, 300 Series Stainless Steel, or INCONEL® Alloys are used to manufacture Bellevilles for high temperature applications, such as those in manufacturing, oil refining, transportation, and downhole drilling.
Our flange bolting, available in 15,000 to 60,000 psi bolt stress, reduces leakage and extends application life in pipelines, valves, and pumps.

Transportation
For the high stress requirements of automotive, locomotive, trucking, and heavy equipment components, BelleFlex® ball bearing disc springs are an excellent choice. Bellevilles are widely used in hydraulics, brake assemblies, train trucks, clutches, and transmissions, among other components. Some applications in the transportation industry may use radial ball bearings. The rolling elements of radial ball

Energy
BelleFlex® Belleville disc springs are used in the production and distribution of energy. They are essential to wind turbine brake assemblies, bus bars, motors, transformers, wind mill propellers, and power plants. Used singly or stacked, as is common practice for wind turbine brake assemblies, Bellevilles decrease the probability of joint failure and keep electrical connections
-
Pumps & Valves
Our engineers at BelleFlex® are experienced with Belleville applications for pumps, valves, and emission leakage control systems. Our flange bolting is used regularly in pumps and valves to help eliminate flange leakage caused by bolt stretch, gasket creep, and cycles of thermal change. Leakage is greatly reduced, if not eliminated by maintaining load on bolted
-
Downhole Drilling
Downhole drilling can reach extreme depths, and the heat and vibration involved in downhole drilling pose special challenges for equipment. Reliability can be paramount in this application as downhole drilling often occurs on offshore platforms where access to parts and maintenance is limited. Belleville disc springs play a crucial role in downhole shock tools, where

Medical
Belleville disc springs are commonly used in clamping systems, oxygen valves, robotics, and magnetic resonance imaging (MRI). When reliability and precision are top priority, BelleFlex® can deliver to the highest standards. With more than 20 years of engineering experience, the BelleFlex® team brings an expert level of mechanical and metallurgical skill to the design of

Oil Refining
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 joints, resulting in less waste and downtime. Incorporating a custom Belleville application such as “live
