The 10 mm external retaining ring beside the 9 mm and the 11 mm

The 10 mm is number 8, counting from the smallest, of the 18 DIN 471 external retaining rings published here, from 3 mm to 20 mm.

• Ring thickness (s): 1 mm on the 10 mm external retaining ring, the same on the 9 mm and the 11 mm.
• Ring thickness, limits (s_lim): 0.94 to 1 mm on the 10 mm external retaining ring, the same on the 9 mm and the 11 mm.
• Free diameter (d3): 9.3 mm on the 10 mm external retaining ring, against 8.4 mm on the 9 mm and 10.2 mm on the 11 mm.
• Free diameter, limits (d3_lim): 8.94 to 9.4 mm on the 10 mm external retaining ring, against 8.22 to 8.46 mm on the 9 mm and 9.84 to 10.3 mm on the 11 mm.
• Lug height (a): up to 3.3 mm on the 10 mm external retaining ring, the same on the 9 mm and the 11 mm.
• Radial width (b): 1.8 mm (reference) on the 10 mm external retaining ring, against 1.7 mm (reference) on the 9 mm and 1.8 mm (reference) on the 11 mm.
• Plier hole diameter (d5): at least 1.5 mm on the 10 mm external retaining ring, against at least 1.2 mm on the 9 mm and at least 1.5 mm on the 11 mm.
• Groove diameter (d2): 9.6 mm on the 10 mm external retaining ring, against 8.6 mm on the 9 mm and 10.5 mm on the 11 mm.
