Recessed cap is 1mm deeper inside the shell than conventional bearings to reduce dirt intake.
Pre-lubricated with a mixture of three different oils for the smoothest ride possible.
The unique "V-groove" construction makes the moving parts less exposed to external conditions leading to a noiseless and virtually invincible bearing.
Designed for a cycle of 60,000 hours of continuous 24/7 use.
Withstand temperatures of -40 to 248 degrees Fahrenheit.
