Design characteristics

Designed to meet both customer and FAA quality standards.
 The bearing performance enhancement scheme numbered 629 is standard in current and emerging applications. These high-grade bearings have tight tolerances and higher performance to withstand the peak loads that a large jetliner continuously produces during its landing.
Special surface treatments are available to further improve wear, fatigue and friction.
Application

The combination of the main and front wheels of private, commercial and military aircraft.
 
Special surface treatment for aerospace bearings

Timken's special surface treatment in aircraft landing gear wheels can effectively solve the rim/roller end-scratch problems that are common in aerospace applications.
