- 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"
