Configuration Notes: This Product Is No Longer Available, Had A Machined Friction Facing For Slightly Less Torque Pulsation In Tension Control Applications, The Standard 802850 Is Very Similar In Performance Or 802862 Has The Smoothest Precision Friction Interface
Application Considerations: Originally Had Tighter Friction Disc Tolerances For Reduced Torque Pulsation At Low Differential RPM's
The Tighter Friction Disc Tolerances Were Dropped In 1996 Making It The Same As 802850
There Is No Direct Replacement At This Time
If Reduced Torque Variation Is Needed Request A Unit With A "Precision Friction Interface"
