The SKF PHE IS RSB is a flexible coupling that links shafts while absorbing misalignment, vibration and shock. It transmits torque in driven equipment where perfect alignment is not practical. MR Industrial Accessories LLC supplies this coupling and helps US and Latin American customers identify the correct size and replacement parts.

The code breaks down into three parts. PHE is the SKF flexible coupling family. IS identifies the elastic element as thermoplastic polyurethane, a material that resists wear and oils. RSB means the coupling uses a split clamping ring, so it can be fitted or removed without shifting the shafts. The number after the letters, as in PHE IS1220RSB, sets the size within the series and defines the coupling's dimensions and torque capacity. Reading the code this way makes it easier to order the right unit or a replacement insert.

These couplings are found in centrifugal pumps, compressors, fans, conveyor drives and machine tools. They are common in food, chemical and petrochemical plants, metalworking shops, water pumping stations and central air conditioning systems. Their ability to damp vibration helps protect bearings and extend the life of the connected equipment.

When selecting a PHE IS RSB coupling, check the nominal and maximum torque of the drive, the operating speed, the shaft diameters and the load type. The polyurethane element accepts moderate angular and radial misalignment, but the shafts should still be aligned closely to avoid extra stresses. The split ring allows installation without dismantling the assembly. Confirm that the hubs fit the shafts with the recommended fit and that the fastening screws are tightened correctly.

SKF PHE IS RSB couplings can interchange with flexible couplings from other makers when the shaft diameter, torque and speed match. There is no universal cross-reference, because each manufacturer uses its own series and codes. For a replacement, compare the critical measurements and performance data. If you send the original coupling details or your shaft measurements, our team can point you to the right option.

To confirm an SKF PHE IS RSB coupling for your application, send the complete part number by WhatsApp or email. We can also quote the replacement elastic element if you already have the hubs. Include the part number and your equipment data, and our team will reply promptly with a quote or an equivalent suggestion.
