ABSTRACT:
A roll neck sealing device comprising a neck seal consisting of an inside neck seal and an outside neck seal, both fitted to the outer surface of the neck portion of a roll, and a preventive means, one end of which is secured to the outside neck seal and the other end of which is inserted through a tapered hole, formed in the inside neck seal, into a core hole formed in the fixing pin secured to the end of the sleeve, said preventive means being adapted for preventing relative rotation between the neck seal and the sleeve, whereby the axial length over which the preventive means is inserted into the fixing pin is set greater than the maximum allowable axial play between the sleeve and the bushing, said axial play being caused when the sealing member is being replaced.
