Four-Row Tapered Roller Bearings   48290DW/48220/48220D

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

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

TQIT (Tapered Bore Four-Row Assembly)

Type TQIT bearings have a tapered bore that is matched and continuous through the inner races.This allows for an interference fit on the backup rolls of high-speed mills, where a loose inner race fit of a straight bore bearing could cause excessive neck wear.

Size range:

ID 123.022 mm to 1004.633 mm (4.8434 in. to 39.5525 in.)
OD 174.625 mm to 2032.000 mm (6.8750 mm to 80.0000 in.)

Design Attributes

Two tapered-bore single cones, one tapered-bore double cone, four single cups and three cup spacers.
Front faces of single cones and both faces of double cone are extended to contact each other.
Tapered cone bores are matched for continuous taper through the cones.
Lubrication delivered through three cup spacers.
Preset, matched assemblies, serial numbered to assure correct installation.
