SKF PHG CX…EP timing belts are toothed transmission elements that mesh with pulleys (sheaves) of the same pitch, ensuring a constant transmission ratio without slippage. They are used in applications where synchronization between shafts is critical, such as motors, pumps and positioning systems. MR Accesorios Industriales offers this line with the backing of more than 80 years in the industrial sector.
The PHG CX…EP designation is interpreted as follows: PHG identifies the SKF timing belt family, CX indicates the tooth profile and pitch, and # is the number of teeth or the coded pitch length. The EP suffix indicates a specific compound or construction variant. For example, PHG CX37EP and PHG CX39EP correspond to different lengths within the same series. To choose, compare the full part number with the original belt or measure the pitch and width.
These belts are used in the food, textile, packaging and automation industries, where synchronization and low maintenance are required. They are also used in compressors, machine tools and power transmission equipment in general. In Argentina, they are commonly found in production lines that need exact transmission ratios and constant speeds, replacing V-belts in critical applications.
To select correctly, check the pulley profile and pitch, the number of teeth and the belt width. Installation requires aligning the pulleys and tensioning according to specification: excessive tension damages the teeth and bearings; too little causes tooth skipping. Check the condition of the pulleys and replace the belt if there is wear, cracks or loss of tension. Lubrication does not apply to the belt, but it does to the pulley bearings.
As for equivalents, timing belts are identified by profile, pitch and length; different brands may offer interchangeable products if those parameters match. Do not rely only on the part number: compare the actual dimensions. SKF is an official brand that MR offers, and we can guide you to find the belt equivalent to the one you use, without inventing part numbers or dimensions that are not in our records.
If you need to replace an SKF PHG CX…EP timing belt, send us the full part number or the measurements of the original belt via WhatsApp. At MR Accesorios Industriales we advise you so you can order the correct reference and avoid machine downtime. We can also quote other equivalent brands if your application allows.

Frequently Asked Questions
- How do I identify the timing belt I need?
- Look for the part number on the old belt, usually printed on the back. If it is not legible, measure the tooth pitch, the width and the pitch length. With that data we can locate the corresponding SKF PHG CX…EP reference.
- What does the EP suffix mean on these belts?
- The EP suffix indicates a compound or construction variant within the SKF line. It does not change the profile or pitch, but it can influence strength and performance in service. Contact us if you have questions about the application.
- Can I replace a belt from another brand with an SKF one?
- Yes, if the profile, pitch, number of teeth and width match. Timing belts are interchangeable between brands when those parameters are the same. Still, check the actual dimensions before installing to avoid failures.
