ある。(Structure) The present invention aims to solve the above-mentioned problems, and includes a step formed on the inner surface of both axial flanges of the outer periphery of the spacer disposed between two inner rings and on the outer periphery of the spacer side end of each inner ring. In a multi-row roller bearing device for a rolling mill equipped with a sealing member between the outer peripheries, a large-diameter step is provided above the spacer,
It is characterized in that the outer end of the large diameter stepped portion is positioned so as to cover the outer end of the inner ring stepped portion with a slight gap.

It consists of an inner ring 104 divided into two parts, and a spacer 105 interposed between both inner rings, and a sealing device 106 is attached to the side ends of the inner and outer rings. Reference numeral 107 denotes a rotating shaft fitted to the inner ring 104, and a small-diameter annular groove 108 is formed in the opposite part of the spacer 105, and the width a of the spacer is the same as that of the annular groove 108.
It is made smaller than the width of. The spacer 105 is an annular body having a T-shaped cross section and integrally provided with both axial flanges 109 on its outer periphery. Inner ring 1 facing the flange 109
04, a stepped portion 110 is formed on the outer periphery, and a slope 111 is formed on the outer end of the stepped portion 110. A large-diameter step 112 is provided on the upper part of the spacer 105, and the outer end of the large-diameter step 112 is positioned so as to cover the slope 111 with a slight gap between the flange 109 and the step 110. An annular seal member 113 is installed in the annular cavity, and a lower lip 115 of the seal member 113 is attached to the lower surface of the stepped portion 110 by a coil spring 114 embedded in the outer periphery.
The side lip 116 is pressed against the side surface of the stepped portion 110 with an appropriate force. Incidentally, the slope 111 is formed in consideration of ease of assembling the seal member 113 when the spacer 105 with a seal member is installed, but it may be omitted if necessary.
