DIN 137 A Curved Spring Washer

DIN 137 A Curved Spring Washers are bowed thin metal washers with a spring rate that is roughly linear between 10% and 80% of their available deflection. Designed for light thrust loads, they provide the most deflection with the least compressive force when compared to other spring washers. As they are loaded (compressed), their outside diameter (OD) will increase and their inside diameter (ID) will decrease so plan for the dimensional changes. They provide an axial preload between two surfaces, whether static or rotating, such as reducing shaft end play. Spring steel, zinc plated and plain finish (which lacks rust protection), stainless steel and spring bronze are available. Size relates to nominal hole size and should be matched to screw size; for example, an M8 washer is used with an M8 screw. DIN 137 B is recommended for new designs.

Product Filter Help

It's easy and fast to find the exact item you're looking for using these filters. Depending on the item, you can filter by Size (diameter and thread), Length, Grade/Class, Material and Finish/Plating. Here's how…

  • Click in a Select box to view the options. It may be necessary to scroll to see the entire list. The number of matching items is displayed in parentheses ( ).
  • Click on the desired item and -- Select -- will change to 1 Selected. You can select more than one item in each Select box. For example, you can select two sizes and 1 Selected will change to 2 Selected.
  • Click in other Select boxes and make more choices. Available options will be based on selections you've already made.
  • Even though there are thousands of fasteners to choose from a particular material or finish may not be available in every size and length. So, try different combinations of filters like Size, Grade and Material to see matching Lengths and Finishes.
  • To deselect a single filter option, click in the Select box and click on the selected option. It will appear at the top of the list in bold. To clear all filter selections, click on the Clear Filters button.

Even after filtering there may be several pages of items. The number of pages will be displayed to the left of the Add All Selected Items button. Click on a page number or the arrows to page forward and back.
