Clamping device for round shafts
The GN928 in 8 to 30mm dia, sizes fits into a hole tangential to the relevant shaft – by appropriate positioning the two spring loaded clamping elements can then be adjusted by hexagonal key to clamp gently or strongly on the round mounting shaft. This design offers delicacy of control with a high degree of ultimate grip on a very wide range of shaft sizes from 6mm to 125mm dia.
For fast frequent operation a clamping handle may be substituted for the normal recessed hexagonal head screw, and for greater convenience, e.g. in difficult orientation either vertically or horizontally. The integral spring aids the sensitivity of clamping and ensures easy release of the clamping elements.
