F Type O-Rings ONLY On The Timken Company

F Type Flex Sleeves (with O-Ring)

For use with F (Flex-Flex) or FFR (Flex-Rigid) couplings.

The F Type coupling consists of two flex hubs, two sleeves (with O-Rings) 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 F Type has a max angular misalignment of 3.0 degrees (1.5 degrees per gear mesh).

The FFR Type coupling consists of one flex hub, one rigid hub, one sleeve (with O-Ring), 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 FFR Type has a max angular misalignment of 1.5 degrees (1.5 degrees per gear mesh).

For larger torques, consider the FHD Type gear coupling in sizes 10 through 30.

Note: F Type Flex Sleeves generally come with the required O-Ring. Other than for replacement purposes, F Type O-Rings are generally not ordered as a stand alone product. The F Type O-Ring works for both Exposed and Shrouded Bolt styles. F Type O-Rings do not work for FA (Alloy Steel) Type couplings.
