46791DW/46720/46721D Four-Row Tapered Roller Bearings

Four-Row Tapered Roller Bearings

Four-row tapered roller bearings provide maximum capacity in minimum space, combining the inherent high-load, radial/thrust capacity and direct/indirect mounting variables of tapered roller bearings.

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

TQOW (Straight Bore with Cone Face Lubrication Slots)

TQOW bearings are similar to TQO bearings.When the fillet and/or filler rings do not already have lubrication slots, they are provided in the faces of the bearing inner race.

Size range:

ID 50.800 mm to 1499.872 mm (2.0000 to 59.0501 in.)
OD 83.337 mm to 2032.000 mm(3.2810 in. to 80.0000 in.)

Design Attributes

Similar to TQO, except that the cone faces have lubrication slots at each face.
Two double cones, two single cups and a double cup with a cone spacer and two cup spacers.
Cone spacers are hardened to reduce face wear.
Numbered serially to assure correct installation sequence.

Applications
Low- and medium-speed rolling mills
