Double direction taper roller thrust bearings

Double direction taper roller thrust bearings

Double-direction axial tapered roller bearings can support very high axial forces in both directions. In these ready-to-fit bearings, the axial internal clearance is set by the ring between the housing locating washers. For example, the bearings are used in blooming and section rolling stands. The metric main dimensions and designations Z-5.TA2 of these special bearings are not standardized.
Size range: 140 - 670 mm (Bore dimension)

Double direction taper roller thrust bearings

Double-row thrust tapered roller bearing is a separable bearing consisting of two outer rings, two inner rings, and a tapered roller in the middle. They can withstand larger loads and are often used in applications such as automotive wheels. The design of this bearing enables it to effectively reduce friction and wear, thereby increasing the efficiency and life of mechanical equipment.


Double-row taper roller thrust bearings are essential in rolling mill equipment and are often paired with multi-row cylindrical roller bearings. The plane shaft washer variation is particularly popular due to its ability to easily accommodate slight eccentricities in the shaft's relation to the housing bore. It can easily be paired with radial bearings with the same radial internal clearance. A spacer sleeve is placed between the two housing washers to ensure the chock's cover screws can be fully tightened without any special spring adjustment. With these bearings, you can be confident in their ability to provide reliable and precise performance, making them a great choice for your rolling mill equipment needs.

The double-row taper roller thrust bearings come with tapered raceway on the shaft and housing washers. These bearings typically have a higher axial load-carrying capacity than the bearings with a plane shaft washer and can also radially locate the shaft to some extent. If the load-carrying capacity of these bearings falls short of the required life, the double-row taper roller bearings with a large contact angle can be used. 

Usually, the double-direction taper roller thrust bearings are mounted in a loose fit on the roll neck and in the chock equipment. Therefore, the shaft washer of most bearings has one or two locating slots. This prevents the shaft washer from rotating on its seating by using keys that engage the slots or other similar methods.


Double-row thrust tapered roller bearings have the following characteristics

High load-carrying capacity: Due to its double-row tapered roller design, this bearing has a high load-carrying capacity and can withstand large radial and axial loads.

High rigidity: Double-row tapered roller bearings have the same inner and outer ring raceway angles, which makes them have high rigidity and can withstand large bending and torsional forces.

High precision: The inner and outer ring raceways of this kind of bearing are precision processed, and the number of contact points between the roller and the raceway is large, so it has high precision and can meet the requirements of high-precision mechanical equipment.

Better rotation performance: Due to the optimization of its design and manufacture, double-row thrust tapered roller bearings can provide better rotation performance, including low friction, low wear, and long life.

Suitable for high-speed operation: The structural design of this bearing allows it to remain stable during high-speed rotation, so it is suitable for applications requiring high-speed operation.

Good alignment performance: Due to its double-row roller design, double-row thrust tapered roller bearings have good alignment performance and can adapt to axial loads under various working conditions.


  • These characteristics make it an ideal choice in many industrial applications, including automotive, aerospace, industrial equipment, and precision machine tools.
