SKF PHG BX…EP timing belts are power transmission components designed to maintain an exact rotational ratio between pulleys. Their internal toothed profile and reinforced construction allow shafts to be synchronized without slipping, making them ideal for applications where precision and repeatability are critical. MR Accesorios Industriales carries this line as part of its broad range of power transmission products.
The PHG BX…EP designation is interpreted as follows: PHG identifies the high-performance timing belt family; BX corresponds to the belt profile and pitch; # indicates the nominal length in inches or the number of teeth, depending on the SKF convention; and EP denotes a special construction, usually with a rubber compound and high-strength tensile cords. For example, PHG BX22.5EP is 22.5 inches long, while PHG BX25EP is 25 inches. Always verify the complete code on the original belt.
These belts are used in industries such as food, textile, paper, plastics, and machine tools. In Argentina, they are common in spindle drives, pumps, compressors, fans, and packaging equipment. Their ability to maintain synchronization makes them suitable for systems with fixed transmission ratios and for applications requiring precise positioning, such as camshafts or intermittent feed conveyors.
To select the correct belt, consider the profile and pitch, which must match the pulleys. The length is chosen based on the center distance and the number of teeth in mesh. It is essential to check pulley alignment and proper tension: excessive tension accelerates wear on the teeth and bearings, while low tension causes tooth jump. Lubrication does not apply, but keeping the environment free of contaminants that damage the compound does.
Regarding equivalences, SKF PHG BX…EP timing belts can be interchanged with other brands that use the same profile and pitch, such as Optibelt, Gates, or Continental, provided the dimensions and tooth type match. However, each manufacturer may have variations in the compound and cord construction, so it is recommended to consult the technical specifications. MR Accesorios Industriales can advise you on compatibility without compromising performance.
To request a quote, simply send the complete code of the belt you need via WhatsApp to MR Accesorios Industriales. If you do not have it on hand, we can help you identify it based on the application and pulleys. With more than 80 years of experience, MR provides personalized technical support to help you find the right timing belt for your equipment.

Frequently Asked Questions
- What does the EP suffix mean in SKF PHG BX…EP belts?
- The EP suffix indicates a special high-performance construction, usually with oil-resistant rubber compounds and high-strength tensile cords. This makes them suitable for demanding applications where greater durability and fatigue resistance are required.
- How do I choose the correct length of a timing belt?
- The length is determined by measuring the center distance of the pulleys and calculating the required belt length. You can also count the teeth on the old belt or read the printed code. If you have doubts, contact us with your machine data.
- Can I replace an SKF belt with another brand?
- Yes, as long as the profile, pitch, and length match. Brands such as Gates, Optibelt, or Continental offer equivalents. Check that the tooth type and width are the same to ensure correct operation.
