Four Row Tapered Roller Bearing

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.)

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

Cone spacers are hardened to reduce face wear.
Numbered serially to assure correct installation sequence.

Four-row tapered roller bearings provide maximumcapacity in minimum space, combining the inherent high-load,radial/thrust capacity and direct/indirec
