Greater Power Density for Two- and Four-Cycle Engines 

Our current developments for high-performance two-cycle engines reduce friction and enhance power density. Recreational four-cycle engines are capitalizing on the friction management innovations we’ve developed for automotive engine valve trains.


  • We creatively meet customer needs by assembling custom connecting rods with special needle roller bearings for the wristpin and crankpin positions.

  • Leveraging both engine and manufacturing technology, we developed an advanced shift shaft for outboard engines. Precision, high-speed welding maintains exact tolerances for optimum mounting and alignment.

We produce a broad range of radial and thrust needle roller bearings as well as bearing assemblies for specialized applications.

Timken® steel components are designed to meet the most demanding standards and tolerances to give you optimum performance.
