Spring WashersJF Engineering has been manufacturing Spring Washers since 2004 & shipped to more than 60 Countries Like Argentina, Germany, Mexico ,Vietnam, Indonesia, USA , Saudi Arabia, UAE, Egypt , Turkey, Venezuela, Italy, Singapore, Malaysia, Australia, New Zealand, Canada & many more.

 

Spring washers, sometimes called disc springs, are a subtype of washers.Spring washers are specifically designed to provide a compensating spring force and sustain a load or absorb a shock. Many design variations have evolved to best serve one or the other of these two basic functions or to optimize both functions in a single part within specific I.D./O.D. limits.

 

We Manufacture Spring Washers in vareity of material including Stainless Steel,Alloy Steel,Carbon Steel,low Carbon Steel,Copper & Copper Alloys,Nickel Based Alloys & other special alloys on request.

 

Orders at JF Engg are guaranteed fast delivery of the Spring Washers in the country. The main reason being we have an excellent warehousing and storage facilities for both finished and semi finished goods.They are made ready as per the urgent requirements of the customers. The Spring Washers are manufactured to sustain very high pressure and product warranty.In 2015 we have stocked more than 188 tons of Spring Washers in all sizes, to cater to immediate delivery and urgent needs of the clients. For small requirements we can dispatch the Spring Washers immediately against the purchase order.

 

There are six primary instances of spring washers.

 

  • Belleville washers can support high loads with small deflections. The load and deflection capability is dependent on height/thickness ratio. These are common in thermal expansion applications. 

  • Crescent washer is meant for lighter loads and produces a small deflection. There is a uniform spring rate throughout the washer's deflection. This is used in flexible, load-cycling applications.

  • Dome washers have a very high load capacity with a small overall deflection. While similar in appearance to a crescent washer, a dome washer has ground curves to create a flatter load-bearing surface.

  • Finger washers are notable for their split construction with protruding flanges. They combine the flexibility of a crescent washer with the distributed load points of a wave washer. They are common for noise and vibration dampening instances.

 

  • Wave washers offer moderate load capacity and deflection, and are typically used as cushions or spacers. These have multiple waves within the washer.
  • Single wave washers are similar to crescent washers but have flattened load points on the washer. This is meant to minimize abrasion against sensitive surfaces.
