Engineered Surfaces & Coatings

The life and performance of basic mechanical components -- shafts, gears, bearings, springs and other parts -- are largely determined by the part's geometry and metallurgy. But there are also remarkable opportunities to enhance the performance of these components by altering their surface.

Where gear teeth mesh, where shafts rotate in housings and where bearing rolling elements ride on raceways, it’s possible to reduce friction and extend equipment life through enhanced surface finishes and special coatings.

Timken experts have invested nearly $80 million to develop these Timken Engineered Surfaces. Customers who turn to Timken for Engineered Surface expertise are realizing many benefits:
