Request Information
FA Type (Alloy Steel) Seals ONLY

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 flex hubs, two FA sleeves 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).

Note: The FA Type seal is generally included when ordering the FA Type sleeve, and not ordered as a stand alone product.
