Wear Rate
Technical Information
WEAR RATE/LIFE EXPECTANCY
The life expectancy of a Simplicity bearing is dependent on
application parameters.
Factors that will affect life:
• Shaft hardness, surface finish, and preparation
• Length of travel • Temperature
• Contamination • Running clearance
• Lubrication • Speed
The Radial Wear chart gives a guideline for a typical
application at 10 psi (.703 kgf/cm 2 ) traveling at 100 ft./min.
(30.48 m/min.).

FACTORS AFFECTING WEAR RATE/LIFE
Shafting requirements for Frelon ® bearing materials.
BEST PERFORMANCE:
• Finish of 8 - 12 RMS (Roughness Measurement System)
• Hardness of Rc 60
ACCEPTABLE PERFORMANCE:
• Finish of 8 - 16 RMS
• Hardness of Rc 35
• Surface finish requirements apply to all three Frelon bearing
materials.
• Rougher shafting can be used, but both bearing and shafting
will wear at accelerated rates and binding may occur.
