Standard F Type

  • Double engagement (‘F’ flex-flex) for parallel and angular misalignment
  • Single engagement (‘FFR’ flex-rigid) accommodates angular misalignment only and is ideal for floating shaft applications
  • Industry standard flange bolt patterns
  • FHD Type standard for sizes 10 through 30 (other sizes available
  • upon request)

Rigid-Rigid FRR Type

  • Designed for connecting two rigidly mounted shafts with no misalignment capability

Alloy Rigid-Rigid FARR Type

  • Longer piloted hubs maintain rigidity and concentricity
  • Used for cantilevered loads such as gear boxes that hang off conveyor systems
  • Alloy steel available for greater strength (FARR)

Mill Motor FMM Type

  • First hub designed with longer universal hub on one end to accommodate straight or tapered shafts
  • Second hub bored to customer specifications
  • Standard design accommodates AISE Mill Motor frame sizes
  • Sleeves and second hub are standard

Floating Shaft FFS Type

  • Two flex-rigid couplings connected by an intermediate shaft
  • Increased ability to accommodate parallel misalignment
  • Accommodate longer shaft separations
  • Standard construction with rigid hubs on outboard (equipment) shafts, flex on inboard (floating) shaft
  • Rigid hubs inboard (on floating shaft) available upon request

Spacer FSPCR Type

  • Drop-out spacer design allows for ease of maintenance without disturbing the equipment mountings
  • Lightweight construction reduces load on equipment bearings

Slide FSL and FSLX Types

  • Allows for a predetermined amount of axial slide
  • Longer hubs and sleeves available to accommodate additional slide capacity
  • Custom slide lengths available

Shear Pin FSHP and FSHPB Types

  • Designed to limit and protect equipment against excessive torque or sudden shock loads
  • Shear pins designed and manufactured to shear at predetermined torque loads
  • Pins are inserted in hardened bushings to minimize wear
  • Easy to install new pins
  • Available with bearing support to maintain alignment after the pins shear

Standard Vertical FVX Type

  • Designed for use with vertical shafts
  • Vertical kit prevents shafts from contacting each other
  • Maintains ability to accommodate misalignment
  • Available in vertical floating shaft design

Limited End Float FLEF Type

  • Designed for equipment with sleeve bearings
  • Designed to limit axial travel of the rotor in the motor and prevent the rotor from coming into contact and damaging sleeve bearings

  • All AISI 4140 Alloy Steel Design
  • No rubber seals – metal labyrinth design
  • Standard with exposed bolts
  • Fully interchangeable with Industry standards
  • Ideal for higher temperature applications

Standard FLA Type
