Nord surface treatment resists fretting rust

A Nord Drivesystems product story
Edited by the Engineeringtalk editorial team Sep 24, 2009

Nord Drivesystems has developed a surface-treatment option for hollow drive shafts that resists the formation of fretting rust or friction corrosion.

The Nord RS coating option, available across its range of gearmotors, produces a hard-wearing, corrosion-resistant layer of approximately 10um thickness that reduces surface-friction characteristics of the hollow shaft and reduces the formation of fretting rust.

The treatment allows easy gearmotor shaft removal and eliminates the potential for destruction of the insert shaft.
