Super-TF Four Row Tapered Roller Bearings

NSK Super-TF four row tapered roller bearings are engineered specifically to accommodate heavy and impact loads transmitted – radially and axially – as steel passes through rolling stands and is reduced in thickness. They also deliver unrivalled long-life durability and wear resistance under the relentless exposure to punishing heat, mill scale contamination and water penetration.

Design Features

Special design high capacity four row tapered roller bearing
Manufactured with long-life Super-TF steel for dramatically longer service life under contaminated operating conditions
With machined steel window- and pin-type cages
Spiral groove on the inner ring bore prevents creeping wear on the roll neck shaft
Available as open or advanced heat- and water-resistant sealed-type bearings
Sealed types available with long-life AQGRD R1 water-resistant grease
Corrosion resistant phosphate coating option for inner ring
Outer ring lubrication grooves and holes
With special radial and axial internal clearances
Available in inch and metric design types

Operating Benefits

Higher reliability and longer operating life with Super-TF steel, reducing bearing replacement and maintenance intervals
Higher load capacity derived from optimized internal design, as much as 35% greater than conventional sealed bearings
Sealed-clean solution extends bearing performance exponentially, significantly reducing grease consumption and corresponding maintenance costs / downtime
Sealed bearings promote a cleaner work environment
