Quick-2-Lock ® Hubs
Tool Steel For 5mm to 16mm Shafts
Ød
• Quick and easy installation - Just tighten the nut
• Positive release for removal or adjustment
• Eliminates expensive machining operations -
Such as cutting of keyways, turning of snap ring
grooves, splines, shoulders and threads for lock
nuts, drilling and pinning
• Drastically relaxes shaft and hub tolerances,
permitting the use of commercially finished
shafting

L2
Permissible Tolerance on Shaft Bore:
For 5mm thru 16mm 0.04
For 17mm thru 19mm 0.08
• Smaller diameter shafts (and bearings) may be
used, offering equal strength and stiffness
because of the rigidizing effect of Quick-2-Lock
and because of the elimination of keyways
• Infinite lateral and circumferential positioning
• Quick and easy removal
• Excellent concentricity
• Greater shaft strength and stiffness
• Unaffected by vibration and torque reversals

The "torque on nut” column represents values which are necessary to obtain the
maximum transmissible torque/thrust.
