Tapered roller bearing classification single row circular cone roller bearings have a case and its ring and a set of tapered roller by basket shape cage cover into an inner ring components. Outer and inner ring components can be separated, according to ISO tapered roller bearing external dimensions standard regulation, any a standard type of tapered roller bearing's outer or inner ring components should be able to and the outer or inner ring components and implementation of international exchange. That is the outer of except external size, tolerance must be in accordance with ISO492 (GB307) specified, inner ring component cone Angle, component cone diameter and so on also must comply with the relevant provisions of the exchange.

 Double row circular cone roller bearing housing washer (or inner ring) is a whole. Two inner ring (or outer) small face similar, and there is a baffle, clearance is to rely on the thickness of the baffle to adjust, can also be used to adjust the thickness of the baffle double row circular cone roller bearing preliminary interference.

Four row circular cone roller bearings, the bearing performance and double row circular cone roller bearings basic same, but more than double row circular cone roller bearings bear radial load is bigger, limit speed slightly low, mainly used in heavy machinery, such as rolling mill, etc
.
Many seal double, four row circular cone roller bearings, ZWZ provide long life and sealing double, four row circular cone roller bearings. To bearing for personalized new design, change all sealed bearing traditional design methods, the use of sealing and dust combination of new type sealing structure, improve the sealing effect and improve the sealing performance. Many seal double, four row circular cone roller bearings and open structure bearing, compared to life increased 20% ~ 40%; Lubricant consumption reduced by 80%
