ZYS® Tapered roller bearings

Main structural forms

1.Single row tapered roller bearing

Single row tapered roller bearing can limit the axial displacement of the shaft or shell in one direction and bear the axial load in one direction. Additional axial force is generated under the action of radial load. Therefore, in the two supports of the shaft, the end faces of bearing outer ring and bearing inner ring are oppositely mounted. If used alone, the applied axial force must be greater than the additional axial force. The 313 series tapered roller bearings have large contact angles (27°~ 30°) and can withstand large axial loads. The contact angle of tapered roller bearings in other series is between 10°and 18°.

2. Double row tapered roller bearing

Double row tapered roller bearing has a pair of raceway outer ring and two inner rings, and a middle spacer between the two inner rings. The thickness of the spacer can be adjusted to adjust the bearing clearance. Double row tapered roller bearing can bear the bidirectional axial load while bearing the radial load. It can limit the bidirectional axial displacement of the shaft or shell within the axial clearance range of the bearing.

3. Four row tapered roller bearings

Four row tapered roller bearings adopt two double raceway inner rings, one double raceway outer ring and two single raceway outer rings, and there are spacers between inner ring and outer ring for adjusting clearance. It has similar performance with double row bearing: large radial load and low limit speed. Four row tapered roller bearings are mainly used for heavy machinery, such as rolling mill.

Spherical roller bearings have two rows of rollers that are mainly used for withstanding radial loads and also axial loads in either direction. Self-aligning roller bearings have high radial load capacity, especially suitable for heavy load or vibration load, but can not withstand the axial load. Spherical roller thrust bearings have good self-aligning properties and can compensate for the coaxiality error. 

ZYS® needle roller bearings
 

The needle bearing is roller bearing with a cylindrical roller, which is both thin and long with respect to its diameter. In spite of the smaller cross section, the bearing still has a high load bearing capacity. The needle bearing is equipped with thin and long rollers (roller diameter D ≤ 5mm, L/D ≥  2.5, L means the length of the roller), therefore its radial structure is compact. When the inner diameter size and load capacity are the same as those  of other types, the outer diameter is the smallest, which is particularly suitable for a support structure in which the radial installation size is limited.

This type of bearing has a radial needle and thrust full of ball, or with a thrust ball, or with a thrust cylindrical roller, or with the angular contact ball into one, can withstand unidirectional or two way axial load. Can also be designed according to the user's specific structural requirements.
