CORELESS SEAL AND ROLLING BEARING

摘要

A coreless seal 11 for being assembled in a shell-type roller bearing provided in a shell-type roller bearing comprises an elastic annular member 12. An outer diameter B of the coreless seal 11 for being assembled in the shell-type roller bearing is a dimension provided by adding interference 2A for an amount of thermal shrinkage to an inner diameter C of a shell-type outer ring. Since the annular member 12 shrinks in a direction shown by an arrow W at low temperature, the outer diameter of the coreless seal 11 for being assembled in the shell-type roller bearing is reduced from B to B'. However, since the outer diameter B is provided with the dimension A obtained by adding interference for an amount of thermal shrinkage, the coreless seal 11 for being assembled in the shell-type roller bearing has interference A' in its outer diameter B' even after the shrinkage.
