SR-EM-2805 Shaft Rings
Product Description
Radially Assembled, External ‘E’, JIS
Perhaps the most popular and widely used radial retaining ring is the “E” (so named because it is shaped like the letter “E”). Three prongs make contact with the bottom of the groove and provide a shoulder for effective retention of assemblies.
For plated rings, add 0.05 to the listed maximum thickness. Maximum ring thickness will be a minimum of 0.005 less than the listed groove width (W) minimum.
