The outer ring (or inner ring) of a double row tapered bearing is a whole. The small end faces of the two inner rings (or outer rings) are similar, and there is a spacer in the middle. The clearance is adjusted by the thickness of the spacer. The thickness of the spacer can also be used to adjust the pre-interference of the double-row tapered bearing.

Four-row tapered bearing, the performance of this kind of bearing is basically the same as that of double-row tapered bearing, but it bears a larger radial load and a slightly lower limit speed than double-row tapered bearing, and is mainly used for heavy machinery.

Multi-sealed double and four-row tapered bearings, ZWZ provides long-life, multi-sealed double and four-row tapered bearings. Carry out a new personalized design for the bearing, change the traditional design method of the fully sealed bearing, and adopt a new type of sealing structure combining sealing and dustproof to improve the sealing effect and improve the sealing performance. Compared with open structure bearings, the multi-sealed double and four-row tapered bearings have a 20% to 40% increase in service life; lubricant consumption is reduced by 80%.
