Volute springs, designed&manufactured according to JB/T11698-2013 standard (SHANGHAI HEGONG participated in drafting the standard). Its main features are small size and large load. HEGONG Volute springs is widely used in small spaces and large loads for vibration reduction. It has three structures as Equal helix angle, Equal pitch, and Equal stress.

U-shaped spring for elevator safety gear also be known as "U-shaped spring", "safety gear spring", "elevator safety gear leaf spring", mainly be used for progressive elevator safety gear. Safety gear is the most important safety component in an elevator, the safety of the elevator just can be guaranteed with safe and effective safety gear. And the HEGONG safety gear spring is the core component of safety gear, it is the last barrier of elevator safety. When the elevator falls out of control and exceeds the limited speed, the U-shaped spring CHINA starts to work, which stops the lift car in emergency and clamps it on the guide rail, ensure the safety of the elevator passengers. We have been working closely with a number of well-known elevator manufacturers, and developed U-spring for a number of progressive safety gears successfully. If you have any questions, please contact us (Tech@DiscSpringsMFG.com), our technical engineers will work closely with you to design, develop the proper spring according to your requirements.

Wave springs also are known as "wave spring washers" are round elastic parts with several sine waves on the metal foil ring. There are several structures as the table, including "Single-turn wave springs with partially overlapping", "Single-turn wave springs with gap", "Closed Single-turn wave springs", "Multi- turn (Peak to Peak) wave springs", "Multi-turn (Peak to Peak) wave springs with Shim Ends", "Nested wave springs". Wave spring China is a precise elastic element, which is suitable for mounting in the parts with limited installation space and stiffness requirements that other elastic elements cannot meet. Due to its unique structural form, the total height and working height of the wave spring are lower than traditional elastic elements, so it can reduce the space size of the parts and the overall cost of the product, and has an excellent cost performance.

Serrated Safety Washers is a kind of Belleville Disc Spring with trapezoid cross section and serrations on both sides. Serrated Safety Washers is connected with bolt or screw, it can prevent bolt relaxation after vibration by increasing the friction resistance. Serrated safety washers China are available in two different types: S type is suitable for normal duty, available for screw sizes: M1.6 to M36. VS type is thicker and therefore achieves higher pretensioning loads, be used with high strength bolts, available for screw sizes:M5 to M36. m10 washer dimensions supplier surface Condition And Corrosion Protection: Polish Phosphating and oil Mechanical Zinc Plating Chemical Nickel Plating Docromet / Geomet Coating Electrophoresis If you require an item with different dimensions, material or surface treatment, please contact us (Tech@DiscSpringsMFG.com), our technical engineers will work closely with you to specify or design, and then manufacture the proper serrated safety washer for your application.

Flange Washers also be known as "Flange Bolting Washers", "Spring Washers", be used for the connection between flange and bolt. Its application equipment includes: Reactor, stirrer and heat exchanger flange bolts; Pumps, Fans, Centrifuge Flanges and Anchor Bolts; Power bus and copper alloy bolts;Pipe flange and valve flange bolt. Flange Washers are widely used in industries such as Petrochemical, Power, Metallurgy, Paper, Pharmaceuticals, Food Processing, etc. Bolt flange joints are widely used in pressure vessel and pipe connections, and Leakage is the main failure mode of bolt flange connections. The main causes of leakage includes: differential thermal expansion/contraction, vibration, bolt creep and vibration. By installing flange washers in bolt flange joints, the elastic potential energy stored in the China Flange Bolting Washers can be converted into mechanical energy, to compensate the deformation of gasket and bolt, to ensure the bolt preload meets the sealing requirements, prevent leakage. How do we choose the right flange washers? Firstly, choose size of wholesale flange washers according to the bolt model & required load value. Then select the suitable raw material further according to the application environment. Material such as H13, 17-7PH, Inconel 718 (see the material document for details) are available in case of high temperature, cryogenic (low temperature) and anti-corrosion environment.

Belleville Washers DIN6796 also be known as "Conical Spring Washers", "Heavy Duty Bolting Washers", "Heavy Duty Safety Washers", "Spring Washers", "Belleville Springs", etc. Belleville Washers are widely used in industries such as national defense, metallurgy, engineering, electric power, machine tools, etc. Heavy Duty Safety Washers DIN6796 is a specialty version of Belleville Spring Washer used to improve security of bolt connection, manufactured as per DIN6796 standard. It is applicable to the static bolting applications in the medium and high strength range. Belleville Washers supplier helps to balance the stress relaxation in bolt / nut assembly, and has the following functions for loss of preload force, thermal expansion and contraction, and compression of seals caused by wear, deformation and creep of wearing parts: a. Have enough elasticity to improve the whole elasticity of the connecting pair. b. The inherent elastic force can compensate for the loss of preload force, meet the clamping force requirements, and ensure the reliability of the connection pair.

Disc Springs for Valves, also be known as Belleville Springs for Valves, Belleville Washers for Valves ... Disc springs are widely used in various types of valves such as Ball Valves, Regulating Valves, Globe Valves, Pigging Valves, and Sea Valves. The load of Disc Springs is large with small deflection, they can provide sufficient valve seat sealing force. The role of the Disc Spring inside the valve is to maintain sufficient contact pressure on the joint. Using Hegong Disc Springs Stacks either in series or parallel, obtain the required force and stroke, to meet the needs of each valve. Disc Springs Stacks apply a pressure and absorb the contraction and expansion that may occur due to pressure, temperature, or relaxation. Depending on the working environment, Belleville Springs for Valves can be produced by material such as Inconel750, Inconel718, 17-7PH. These materials have good corrosion resistance and high temperature resistance, can also provide adaptable working loads under harsh conditions and high temperature environments. Disc springs are the key part to fix Ball Valve, its performance will directly affect the sealing effect of the valve. When we design and manufacture Disc Springs for Ball Valves, we should pay attention to the following points.

Disc Springs for Ball Bearing, also be known as “Bearing Preload Disc Springs”, they are assembled with the radial ball bearings, act as a compensator of thermal expansions during their working. Using Disc Springs to preload radial ball bearings, helps to maintain positioning accuracy, eliminate shaft end play, and minimize vibration and shaft deflection by distributing the load evenly around the bearing race, extends the bearing life, eliminate excessive running noise. In most cases, the outer race of the ball bearing is preloaded with the Disc Spring, and in some cases it is desirable to preload the inner race of ball bearing.  The recommended load value is achieved when the disc spring is deflected to 75% of the initial cone heights (ho). The proper designed ho/t ratio makes a load of disc spring remains nearly constant for a large deflection range.  Disc springs for valves are designed to operate within 20%-80% of their total deflection. Misuse can result in overload, bigger error, or premature fatigue failure. If your working environment requires disc springs to work outside this range, HEGONG SPRING ® engineers can provide guidance or recommend other solutions.
