Double-row cylindrical roller track bearing of the present utility model, one end of bearing inner race is provided with chimb, and lubricant grease has better seal effect, can reduce the volatilization of lubricant grease largely；Middle spacer ring it is provided with between two line column rollers；Bearing inner race can be positioned and limit cylindrical roller by middle spacer ring, the boss one that bearing outer ring is provided with is can be spacing, two is pass form heat radiation with heat, makes the heat that cylindrical roller produces in the course of the work pass in time, and loose rib is to carrying out spacing to cylindrical roller；Above-mentioned setting, it is ensured that between bearing inner race, bearing outer ring and retainer, space is relatively big, has good heat dispersion；Guarantee lubricant grease is played good sealing function, there is good lubricant effect；And the bearing of said structure, easy to assembly。
As preferably, this utility model further technical scheme is:
The middle part of the inner peripheral surface of described bearing outer ring is provided with boss, and the width of boss is corresponding to the width of middle spacer ring, and the both sides of boss are the raceway of cylindrical roller。
The width of boss is corresponding to the width of middle spacer ring, it is possible to better cylindrical roller and retainer are positioned。
The inner peripheral surface at described bearing outer ring two ends is provided with seal groove, and the root of boss is provided with oil groove。
The sealing property of bearing can be improved by arranging seal groove further, oil groove is set and stores lubricant grease, it is possible to improve the greasy property of bearing。
The inner peripheral surface at described bearing outer ring two ends is provided with sealing station, and seal groove is arranged on the inner of sealing station。
Sealing station can coordinate with sealing ring better, improves the sealing property of lubricious oils and fats, and seal groove is arranged on the inner of sealing station, and sealing ring arranges convex edge corresponding with seal groove, it is possible to improve sealing property further。
The width of described middle spacer ring is more than the 1/2 of cylindrical roller width。
The width of middle spacer ring is bigger, it is possible to increase the inner space of bearing, improves lubricating property and the heat dispersion of bearing。
The outer circumference surface of the outer circumference surface of described loose rib and middle spacer ring is at sustained height。
Above-mentioned setting, it is possible to facilitate lubricant grease in the flowing of Bearing inner, make the lubrication that bearing maintenance is good。
