SKF
Double Row Tapered Roller Bearings
Double row tapered roller bearings incorporate two rows of rollers and two inner rings (cone assembly) with a common outer ring (cup). They handle high radial and bidirectional axial loads, offering high stiffness and load capacity in a relatively compact design. SKF offers TDO and TD types, including sealed versions. Common applications include heavy-duty wheel hubs for trucks and trailers, rolling mill work rolls, and mining machinery. Their ability to carry substantial overturning moments makes them suitable for applications with cantilever loads. The preload or clearance is set during manufacturing, so the unit is ready to install. SKF Explorer double row tapered roller bearings exhibit enhanced resistance to debris denting and longer life in contaminated environments, contributing to extended maintenance cycles in off-highway and industrial contexts.

Double Row Tapered Bearings in Truck Wheel Ends
Truck and bus wheel bearings must sustain heavy radial loads plus cornering thrust. Double row tapered units (often with integrated oil seals) provide a compact, long-life solution. SKF’s hub bearing unit evolution often starts from these double row principles.
Double Row vs. Matched Single Row Tapered Bearings
Double row bearings are simpler to handle as a single integrated assembly. Matched single rows remain preferred when housing design requires independent fitting or when width constraints allow different spacing. Both share the combined load characteristic.
