A flexible jaw coupling from the SKF PHE FRC line, the RSB version connects driving and driven shafts while tolerating a certain amount of misalignment. It suits pumps, gearboxes, compressors and similar machinery where a dependable flexible link is required. MR Industrial Accessories supplies this SKF series and helps buyers match the coupling to their application.
Reading the code: PHE FRC is the jaw coupling family from SKF, the figure that follows tells you the size, and RSB signals the build that uses a rubber elastic element together with bronze bushings, giving the coupling its particular stiffness and damping behavior. Available sizes in this series are 70, 90, 110, 130, 150, 180, 230 and 280. The smallest is PHE FRC70RSB; the largest capacity comes with PHE FRC280RSB.
Typical duties include centrifugal pumps, gearboxes, compressors, fans, conveyor belts and machine tools. Chemical, petrochemical, food processing and mining operations use them frequently. Because the design takes up angular, radial and axial offset, bearing and seal wear is reduced and equipment tends to run longer between repairs.
Choosing a size means checking the torque the drive must carry, the operating speed, the shaft diameter and the misalignment you expect. During installation, align the shafts accurately before fitting the elastic element. Rubber jaw versions run without lubrication, but screw tightness and bushing condition should still be inspected on a regular basis. Proper mounting keeps vibration and early failures away.
These couplings interchange with other makes built to the same jaw standard and dimensions. Before replacing one, confirm shaft diameter, hub length and nominal torque. Equivalences between manufacturers exist, yet part numbers do not always line up, so dimension checks matter. MR can assist in identifying the correct replacement.

Frequently asked questions
- What does RSB indicate in an SKF PHE FRC coupling?
- It identifies the configuration that combines a rubber elastic element with bronze bushings, a setup that damps vibration and absorbs misalignment, which suits applications with varying loads.
- Is lubrication needed for PHE FRC RSB couplings?
- No. The rubber element and self-lubricating bushings mean no grease or oil is required. Periodic checks of element wear and screw tightness are still recommended.
- How do I pick the correct PHE FRC RSB size?
- Look at nominal torque, operating speed, shaft diameter and the type of misalignment involved. The number in the designation (70, 90, 110 and so on) sets the size, and higher numbers carry more capacity. Share your application data with us and we will guide you.
