Four-Row Tapered Roller Bearings LM742749DW/714/714D

Four-row tapered roller bearings provide maximumcapacity in minimum space, combining the inherenthigh-load,radial/thrustcapacity and direct/indirect mounting variablesof tapered rollerbearings.

Their main application is on the roll necks of rolling millequipment.Allfour-row bearings are supplied as pre-set matchedassemblies with allcomponents identified to ensure correct installationsequence.

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 racespacerand twoouter race spacers.

Slots in the inner race spacer permit lubricant to flow from the bearingchamber to the roll neck.The inner race spacers are hardened tominimizeface 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.)

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.

Applications

Low- and medium-speed rolling mills
