SKF PHE FRC HTB couplings are flexible elements that connect shafts in industrial machinery. They compensate for misalignment between shafts and reduce vibration, helping to protect bearings, gears and motors from dynamic loads. MR Industrial Accessories LLC supplies this line as part of its power transmission offering and can help you select the appropriate model.
The part number breaks down into three parts. PHE is the SKF coupling family. FRC denotes the flexible coupling type. The number that follows—70, 90, 110, 130, 150, 180, 230 or 280—is the nominal size, which sets the torque capacity and the allowable shaft diameter range. HTB indicates the mounting configuration, typically with a taper bushing for quick installation. Examples include PHE FRC70HTB, PHE FRC90HTB, PHE FRC110HTB, PHE FRC130HTB, PHE FRC150HTB, PHE FRC180HTB, PHE FRC230HTB and PHE FRC280HTB.
These couplings appear in food processing, cement, mining, paper and water treatment plants, wherever electric motors, gear reducers, pumps, fans and conveyors are found. Their ability to handle angular, radial and axial misalignment helps lower wear on bearings and seals. For maintenance teams, this translates into fewer adjustments and less downtime.
When selecting a coupling, review the application's nominal and maximum torque, operating speed, shaft diameters and load characteristics. Proper installation calls for accurate shaft alignment, verification of axial and radial clearance, and lubrication as specified. Taper bushings simplify mounting and removal without damaging the shafts. As part of routine maintenance, inspect the flexible element and check that screws remain tight.
In terms of interchangeability, SKF PHE FRC HTB couplings can serve as replacements for other flexible couplings from brands such as Rexnord, Falk or KTR, provided that interface dimensions, torque and speed ratings are matched. No universal interchange table exists; each case requires checking diameters, keyways and the gap between shaft ends. Contact MR to confirm compatibility before substituting an existing coupling.

Frequently asked questions
- What does HTB mean in the coupling designation?
- HTB refers to the mounting variant with a taper bushing. This allows quick and secure fixing to the shaft, and in some cases eliminates the need for a keyway. It simplifies mounting and dismounting, which is useful when maintenance speed matters.
- How do I choose the right PHE FRC HTB coupling size?
- Base your selection on the application torque, rotation speed and shaft diameters. Consider maximum torque and expected misalignment. MR can assist you in selecting the correct model using the details of your drive.
- Does this coupling require lubrication?
- SKF PHE FRC HTB flexible couplings generally do not need lubrication because the flexible element is elastomer. Still, it is wise to inspect the element and keep the assembly clean. Refer to the technical manual for specific conditions.
