Double-Row Tapered Roller Bearings (TDI Type) Performance


ZYS double row taper roller bearing is recommended to use when the axial load is larger than the radial load or only axial load exists.

In certain cases, a spring is provided between the housing shoulder and cup end face for preloading instead of using a cup spacer.

Double-Row Tapered Roller Bearings (TDO Type) Performance


TDO type of this bearing is composed of a double cup, two cones and a cone spacer. The bearing internal clearance has already been set by using the cone spacer, so parts must be combined according to the serial number and matching symbol. The double cup has an oil slot and oil holes. 

The bearing can carry both radial and axial loads, so it can be used as a fixed-end bearing. It is also used frequently on the free end to relieve the shaft elongation or contraction between the cup and housing.

Four-Row Cylindrical Roller Bearings Performance


ZYS four-row cylindrical roller bearings are mainly used for heavy machineries, such as mounted on the backup roll of blooming mill, section mill, plate mill, etc. ZYS four-row cylindrical roller bearings are mainly used on the roll necks of hot or cold rolling mills used for forming blooms, plates, and other stock. There are many variations of the bearings: the inner and outer rings can have ribs or not, the inner ring can be in one or two pieces, the bore can be cylindrical or tapered, and other variations. 

All four-row cylindrical roller bearings only support radial loads, therefore, they must be used in combination with thrust bearings such as angular contact ball bearings or tapered roller bearings.
