ABSTRACT:
A telescopic drive spindle assembly for a rolling mill permits the assembly to accommodate axial displacement of the roll. The assembly has first and second overlapping members with a piston in one member being displaceable in a cylinder in the other member. The piston defines a chamber and a quantity of gas in the chamber serves to urge the piston in the direction out of the cylinder so as to increase the effective length of the drive spindle.
