The 9 mm E-clip beside the 8 mm and the 10 mm

The 9 mm is number 8, counting from the smallest, of the 11 DIN 6799 E-clips published here, from 2.3 mm to 15 mm.

• Clip thickness (s): 1.1 mm on the 9 mm E-clip, against 1 mm on the 8 mm and 1.2 mm on the 10 mm.
• Clip thickness, limits (s_lim): 1.07 to 1.13 mm on the 9 mm E-clip, against 0.97 to 1.03 mm on the 8 mm and 1.17 to 1.23 mm on the 10 mm.
• Mouth width (a): 7.63 mm on the 9 mm E-clip, against 6.52 mm on the 8 mm and 8.32 mm on the 10 mm.
• Mouth width, limits (a_lim): 7.572 to 7.688 mm on the 9 mm E-clip, against 6.462 to 6.578 mm on the 8 mm and 8.262 to 8.378 mm on the 10 mm.
• Outer diameter, installed (d3): up to 18.8 mm on the 9 mm E-clip, against up to 16.3 mm on the 8 mm and up to 20.4 mm on the 10 mm.
• Groove diameter (d2): 9 mm on the 9 mm E-clip, against 8 mm on the 8 mm and 10 mm on the 10 mm.
• Shaft diameter range (d1): 10 to 14 mm on the 9 mm E-clip, against 9 to 12 mm on the 8 mm and 11 to 15 mm on the 10 mm.
• Groove width (m): 1.15 mm on the 9 mm E-clip, against 1.05 mm on the 8 mm and 1.25 mm on the 10 mm.
