FLA Type (Flex-Flex All-Metal Labyrinth Seal) Flex Hubs - Inch (Imperial) Bore

For use with FLA (Flex-Flex All-Metal Labyrinth Seal) and FLAFR (Flex-Rigid All-Metal Labyrinth Seal) couplings.

The FLA Type coupling consists of two special FLA Type flex hubs, two FLA 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 FLA Type has a max angular misalignment of 3.0 degrees (1.5 degrees per gear mesh).

The FLAFR Type coupling consists of one special FLA flex hub, one FA rigid hub, one FLA flex sleeve, 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 FLAFR Type has a max angular misalignment of 1.5 degrees (1.5 degrees per gear mesh).
