<P>PROBLEM TO BE SOLVED: To provide a sealed type double row cylindrical roller bearing sealing a gap between an inner and an outer ring and not interfering with a seal even at a time of run-out of a retainer. <P>SOLUTION: This double row cylindrical roller bearing has a plurality of cylindrical rollers 4 retained by a pair of resin retainers 3 provided between the inner ring 2 and the outer ring 1. Gaps between the inner and the outer rings at both ends of the double row cylindrical roller bearing are sealed by the seal plates 8, padding parts 9a-9d are formed on an outer diameter surface in an abutment inner end side or an inner diameter surface in the abutment inner end side of the pair of resin retainers 3 evenly in a circumference direction, and rotation of the resin retainers are guided by loosely fitting the padding parts 9a-9d on the outer ring inner diameter surface or the inner ring outer diameter surface. <P>COPYRIGHT: (C)2008,JPO&INPIT |
