That allows the collars to be adjusted easily and quickly without tools. The aluminum design delivers low inertia values. The specified tightening torque of the screw is a recommended value with which the collar clamped to a shaft (with closed eccentric lever) is capable of reaching the specified axial load capacity. The details on axial load capacity are non-binding guidance values and do not constitute a warranty of characteristics. Keeping the friction surface of the eccentric lever slightly greased will help to prolong the useful service life. see also... • Semi-Split Shaft Collars GN 706.2 (with Socket Cap Screw) → Page 1148 Information • Ring Aluminum Black anodized • Lever Aluminum Yellow anodized • ISO Fundamental Tolerances → Page 2151 • RoHS Specification 1 2 d 1 d 2 Recommended shaft tolerance h8 b s Tightening torque of the screw in Nm ≈ Axial load in N ≈ min. max.  38 B  6 B  8 B 10 B 12 B 14 B 15 B 16 10 1,5 0,5 133 267  50 B 20 B 25 B 28 B 30 - - - 13 1,5 0,7 311 445  75 B 32 B 35 B 38 - - - - 15 1,5 1,5 467 534 100 B 40 B 42 B 45 B 48 B 50 - - 19 4,5 4,5 556 867 120 B 54 B 55 B 60 B 65 B 70 B 75 - 19 4,5 4,5 890 1379
