LYTBZ produce metric system, British system list, pair, four row circular cone roller bearings structure pattern. Single-row Tapered Roller Bearings This kind of bearing can only limit the axis or an outer covering direction axial translation, to withstand a direction the axial loading. Under radial load's function, the axial force must perform to be balanced. Should two bearings face-to-face or the back to back use. Double-row Tapered roller Bearings This kind of tapered bearing may withstand the bidirectional axial loading during withstanding radial load's. May limit the axis or the outer covering bidirectional end motion in bearing's axial float scope Four-row Tapered Roller Bearings The bearing's performance and double row circular cone roller bearings basic same, but is bigger than the double row circular cone roller bearings withstanding radial load, the limited speed is slightly low, mainly used in the heavy duty machinery, like mill and so on. Multi-sealed double, four Tapered Roller Bearings LYTBZ provides long life, multi-seal pair, four row circular cone roller bearings .We Carry on the personalized brand-new design to the bearing, change the entire sealed bearings tradition design method, use new seal structure pattern which the seal and dustproof unifies, improve seal effect, enhance the sealing paring with the the open structure bearing, the life of the multi-seal pair, four row circular cone roller bearings increases 20%~40% and the lubricant consumotion reduces 80%. The multi-sealed bearings symbolized with postpositioned code number XRS.
