High performance tapered roller bearing
DuraSpexx®, DuraSpexx® Power Rating TIMKEN

To withstand the tough operating conditions found in many industrial applications, Timken offers two product lines that help improve bearing life in intense environments: DuraSpexx® and the DuraSpexx® Power Rating Series.

DuraSpexx bearings are modified designs that offer enhancements to improve bearing life in demanding applications with harsh environments. Timken engineers use sophisticated, application-focused computer programs to help you model your operating environment and recommend specially-designed bearings that yield longer life.

Our DuraSpexx Power Rating Series consists of defined part numbers - tapered single (TS), tapered double outer (TDO) and tapered thrust heavy duty (TTHD) bearings - that have standard lead times. This series leverages our technical capabilities for a 23 percent bearing rating increase and up to a 100 percent bearing life increase.

Design Attributes
