Operating Parameter Notes:
|
Logan Seals / O-Rings are provided in a fluorocarbon elastomer having a 70 durometer. Operating temperature range is -15 to 400 degrees F (-26 to 204 degrees C).
-
Clutch weight: Based upon minimum hub bore. Does not include drive cup and friction discs.
-
R Series: Maximum speed in the R Series at which release springs will overcome the centrifugal head due to fluid remaining in the actuating cylinder. Modified springs are available for heavy duty applications.
-
Cylinder Volume: Upper value units are cubic inches; lower value units are cubic centimeters.
-
Actuating Flow: Based upon an actuating time of 0.1 second. Upper value units are gallons per minute; lower value units are liters per minute.
-
RPM: For higher operating speeds, call Logan.
Logan Outperforms
Electromagnetic Clutches!
Logan has the design and manufacturing capability to replace existing and obsolete electromagnetic clutches with Logan technology.
Logan vs. Electromagnetic Clutches
-
Transmits more Torque and has higher RPM
capabilities within the same envelope
-
Eliminates residual DC magnetism in disc packs
and bearings-reduces downtime
-
Disc Pack, Bearing Kits and Seal Kits for Logan
clutches are available from stock
