DIN 471 External Retaining Ring

DIN 471 External Retaining Rings are retaining rings for shafts, which means they are axially installed into a groove machined in the shaft so the ring can create a removable shoulder that retains components. The tips of retaining ring pliers fit the ring's lug holes to simplify installation and removal by expanding the ring and allowing it to pass over the shaft. Since nearly 360° of the ring contacts the groove, it can tolerate high thrust loads especially compared to radially installed retaining rings. Although size is listed as shaft diameter, the inside (free) diameter of the ring is smaller to accommodate the smaller diameter of the mating groove. However, the specified free diameter only applies to rings that have not been installed—once expanded, the free diameter will measure slightly larger than the specified dimension. They are available in plain finish spring steel and stainless steel.

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.
