Couplings

A coupling is the component that connects two shafts and transmits torque while absorbing misalignment, vibration, and shock. It is selected according to the type of connection, the shaft diameter and length, the torque to be transmitted, and the allowable degree of misalignment. This subcategory has 593 references loaded from SKF and RUADIGON, with jaw, split flange, universal joint, and other construction variants.

The SKF PHE line includes jaw, flange, and articulated couplings. The endings indicate the construction: FTBFLG corresponds to split flange, L to jaw couplings, TGFS to jaw with flange, RSB to jaw with separator, UJMA to universal joint, and SM to jaw with spacer. The X series appears as a normal or solid hub coupling, a simple construction for rigid or semiflexible connections. Codes with a size suffix, such as L035-5MM or SHX75MM, already come with the shaft diameter defined.

Couplings are used in pumps, reducers, fans, conveyors, compressors, and machine tools. A jaw coupling handles moderate angular and radial misalignment; a split flange coupling allows mounting and dismounting without moving the equipment; a universal joint covers larger angles and transmits torque on misaligned shafts. To replace a coupling, it is advisable to identify the component: hub, spider, separator, or flange, as applicable.

To request a quote, send us the complete coupling code, the shaft dimensions (diameter and length), the torque or power and working RPM, and if possible an equivalent to the code shown on the machine. With this information we verify the construction, the hub type, and the associated components. If you do not have the code, a photo of the nameplate or the mounted coupling helps identify it.

You can also inquire about RUADIGON couplings, the other brand loaded in this subcategory, and about the transmission components that accompany the mounting: pulleys, taper bushings, belts, and chains. Write to us via WhatsApp or email with the code and we will send you the quote.
