Four-row tapered roller bearings provide maximumcapacity in minimum space, combiningtheinherenthigh-load,radial/thrustcapacity and direct/indirect mountingvariables of tapered roller bearings.

Their main application is on the roll necks of rolling mill equipment. Allfour-row bearings are supplied as pre-setmatched assemblies with all components identified to ensure correct installation sequence.

TQO (Straight Bore Four-Row Assembly)

TQO bearings are directly mounted and comprised of two double inner races,two single and one double outer race, with an inner race spacer and two outer race spacers.

Slots in the inner race spacer permit lubricant to flow from the bearing chamber to the roll neck.The inner race spacers are hardened to minimize face wear.

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.)
