Flanged Sleeve Gear Couplings
FA Type (Alloy Steel) Flex Hubs with Keyway - Inch (Imperial) Bore
For use with FA (Alloy Steel) Flex-Flex couplings.
The FA Type coupling provides a higher nominal torque value than standard F Type couplings, and consists of two FA Type flex hubs, two FA Type sleeves (with seals) and one accessory kit. Exposed bolts (E) are the standard design for this coupling, though shrouded bolt (S) designs are available upon request through size 5.5. The FA Type has a max angular misalignment of 3.0 degrees (1.5 degrees per gear mesh).
