Elesa has introduced a novel clamping device to be incorporated into equipment mountings where frequent readjustment is required for the quick and precise operation of a mounting shaft/tubular shaft.
The GN928 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 range of shaft sizes from 6mm to 125mm diameter.
For fast frequent operation a clamping handle may be substituted for the normal recessed hexagonal head screw and for greater convenience in difficult orientation either vertically or horizontally. The integral spring aids the sensitivity of clamping and ensures easy release of the clamping elements.
