SKF PHE R HTB couplings are flexible shaft couplings built to handle misalignment, vibration and shock in power transmission systems. Their split sleeve design simplifies installation and removal. MR Industrial Accessories supplies this line to maintenance and purchasing teams across the United States and Latin America.
The code breaks down into three parts. PHE is the SKF coupling family. R tells you it is a flexible coupling with a split sleeve. The number in the middle (12, 16, 25, 30, 35, 40) is the size, which sets torque capacity and maximum shaft diameter. HTB means the sleeve is made for high temperature and high strength. So PHE R12HTB is the smallest size, and PHE R40HTB has the highest capacity.
These couplings show up in food processing, cement, mining, petrochemical and general manufacturing. You will find them on centrifugal pumps, fans, compressors, conveyors and mills, where shafts are not perfectly aligned and vibration needs to be absorbed to protect the driven equipment.
When selecting a coupling, check the system's nominal and maximum torque, the shaft diameters, the rotation speed and the operating environment. Mounting requires precise initial alignment, even though the coupling tolerates some misalignment. These elastomeric sleeve couplings do not need lubrication, but you should inspect the flexible element for wear and verify screw tightness. Follow the manufacturer's instructions for installation.
For interchangeability, SKF PHE R HTB couplings can replace other flexible split sleeve couplings from brands like Fenner, Lovejoy or Dodge, provided the critical dimensions and torque capacity match. Always confirm shaft diameter, hub length and sleeve type. Send us the exact code and we will help you verify.

Frequently asked questions
- What does HTB mean in SKF PHE R couplings?
- HTB indicates a sleeve designed for high temperature and high strength. This lets the coupling keep its flexibility and damping properties in hot or severe conditions.
- Do PHE R HTB couplings need lubrication?
- No. They use an elastomeric element that does not require lubrication. Periodically check the sleeve for wear and make sure the screws are tight.
- How do I choose the correct size of PHE R HTB coupling?
- Consider nominal and maximum torque, shaft diameters and rotation speed. Choose a size that covers those values with a safety margin. If you are unsure, contact us with your application data.
