The 15 mm external retaining ring beside the 14 mm and the 16 mm

The 15 mm is number 13, 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 15 mm external retaining ring, the same on the 14 mm and the 16 mm.
• Ring thickness, limits (s_lim): 0.94 to 1 mm on the 15 mm external retaining ring, the same on the 14 mm and the 16 mm.
• Free diameter (d3): 13.8 mm on the 15 mm external retaining ring, against 12.9 mm on the 14 mm and 14.7 mm on the 16 mm.
• Free diameter, limits (d3_lim): 13.44 to 13.9 mm on the 15 mm external retaining ring, against 12.54 to 13 mm on the 14 mm and 14.34 to 14.8 mm on the 16 mm.
• Lug height (a): up to 3.6 mm on the 15 mm external retaining ring, against up to 3.5 mm on the 14 mm and up to 3.7 mm on the 16 mm.
• Radial width (b): 2.2 mm (reference) on the 15 mm external retaining ring, against 2.1 mm (reference) on the 14 mm and 2.2 mm (reference) on the 16 mm.
• Plier hole diameter (d5): at least 1.7 mm on the 15 mm external retaining ring, the same on the 14 mm and the 16 mm.
• Groove diameter (d2): 14.3 mm on the 15 mm external retaining ring, against 13.4 mm on the 14 mm and 15.2 mm on the 16 mm.
