The SKF timing belt of the PHG line with EPX ending is a power transmission component that combines a high-precision toothed profile with rubber compounds and resistant tensile cords. It is used to synchronize shafts and transmit torque without slipping in equipment where rotation accuracy is critical. MR Accesorios Industriales carries this line as part of its power transmission catalog, with technical advice so you can choose the right belt for your application.

The designation of these belts is read in blocks: the letters PHG identify the family of high-performance timing profiles; the number that follows indicates the pitch length in tenths of an inch or millimeters depending on the profile standard; the letters VX correspond to the type of profile and pitch; and the EPX suffix indicates the construction of the compound and the cords. For example, in PHG 5VX850EPX4, the 5 refers to the pitch, 850 to the length and EPX to the execution. Knowing these fields avoids confusion when ordering a replacement.

These belts are used in drives where slipping is not allowed: textile machines, packaging machines, industrial printers, automation equipment, process pumps and screw compressors. In Argentina you will find them in food production lines, water treatment plants, metalworking shops and synchronized shaft movement systems. They are also used in cutting and conveying equipment where the transmission ratio must remain constant at different speeds.

To select correctly, verify the profile and pitch according to the pulley, the pitch length required by the run and the belt width. Check that the pulleys do not have worn teeth or grooves with burrs. Shaft alignment is key: angular or parallel misalignment accelerates wear on the tooth and the cord. Tension must be the one recommended by the equipment manufacturer; a belt that is too tight overloads the bearings and a loose one jumps teeth. Lubrication does not apply to this type of belt.

As for equivalences, timing belts are identified by profile, pitch and length, not by brand. If you have the original part number, the safest thing is to cross those three data with the SKF PHG EPX designation. Not all brands use the same nomenclature for the compound or the type of cord, so it is advisable to verify the application before replacing. MR Accesorios Industriales can help you interpret the part number and find the equivalent belt within its SKF line.

If you already have the belt part number, send it via WhatsApp to MR Accesorios Industriales along with a photo of the pulley or the equipment. That way we can confirm the profile, pitch and length before quoting. If you do not have it, tell us what machine it is, the number of teeth on the pulleys and the center distance; with that data we guide the selection. The response includes alternatives within the SKF PHG EPX line when the exact part number is not available.
