Bowed (Curved) Washer



  • Bowed (Curved) washers have minimum load build up with maximum washer deflection.
  • Light thrust loads compared to other styles of spring washers.
  • Used to apply tension between two rotating or static surfaces, eliminate “play”, and prevent rattles.
  • The spring rate is approximately linear between 10% and 80% of available deflection.
  • Bowed (Curved) washers have the longest length of “beam” of all spring washers. This gives the most washer deflection with a minimum of pushing effort (load build up) of all spring washers.

Stock Materials:

  • Spring Steel: SAE 1074 / ASTM#A684, hardened to Rockwell C45-50.
  • Stainless Steel: 301 / 302 Stainless Steel to ASTM#A177.

* These are materials we stock in various thicknesses. It does not mean we have finished inventory of all washers in each of these materials.

** Non stock alternate materials that are commonly run are Phosphor Bronze to ASTM#B103, Copper Alloy to UNS#C51000, and 17-7 Stainless Steel.

*** Customer specific materials different than those listed above are commonly run.

Finishes:

  • Steel: Provided Plain Finish. Bowed washers can be provided with a mechanical zinc plating processed in house which eliminates hydrogen embrittlement. A wide range of additional coatings are available: zinc electroplating, phosphate coatings, black oxide, etc.
  • Stainless Steel: provided plain finish.
  • Phosphor Bronze: provided plain finish.
