Four-row tapered roller bearings. TQO series

The performance of the four-row tapered roller bearing is basically the same as that of the double-row tapered roller bearing, but the radial load is greater than that of the double-row tapered roller

  • Size range: ID 50.800 mm to 1500.000 mm (2.0000 in. to 59.0551 in.) OD 83.337 mm to 2032.000 mm (3.2810 in. to 80.0000 in.)
  • Applications: Low- and medium-speed rolling mills Hot rolling mills Cold rolling mills

The performance of the four-row tapered roller bearing is basically the same as that of the double-row tapered roller bearing, but the radial load is greater than that of the double-row tapered roller bearing, and the limit speed is slightly lower. It is mainly used for heavy machines, such as rolling mills. 

Design Attributes:

  • Two double cones, two single cups and a double cup with a cone spacer and two cup spacers.

  • Spacers have slots or holes for lubrication.

  • Cone spacers are hardened to reduce face wear.

  • Numbered serially to assure correct installation sequence.


Installation of four-row tapered roller bearings:
1. The fit between the inner ring of the four-row tapered roller bearing and the roll neck is generally with clearance. When installing, put the bearing into the bearing box first, and then put the bearing box into the journal.
The outer ring of the two- and four-row tapered roller bearing also adopts a dynamic fit with the bearing box hole. First, install the outer ring A into the bearing box. Characters are printed on the outer ring, inner ring, and inner and outer spacers when leaving the factory. The bearing box must be installed in the order of the characters and symbols during installation. Cannot be interchanged arbitrarily to prevent changes in bearing clearance.
3. After all the parts are installed in the bearing box, the inner ring, and the inner spacer, and the outer ring and the outer spacer are axially abutted.
4. Measure the gap width between the end face of the outer ring and the bearing box cover to determine the thickness of the corresponding gasket.

Four-row tapered roller bearings can accommodate combined (radial and axial) loads at low to moderate speeds.  TQO and TQI design are two main types of four row tapered roller bearings. TQOS is an upgrade design based on TQO. It is an advanced design with sealing system. They are used almost exclusively in roll neck applications such as rolling mills.
