SKF PHG series timing belts with XL profile and S ending are toothed power transmission elements that mesh with pulleys of the same pitch to deliver synchronized motion without slipping. They are used when the drive ratio must remain exact and space is limited, such as in automation equipment, industrial printers, and positioning mechanisms. MR Accesorios Industriales offers this line as part of its power transmission range.
The designation of these belts is read in parts. PHG identifies the SKF timing belt family. The number that follows, as in PHG 44-XL-S400 or PHG 60-XL-S800, indicates the number of teeth in the profile. XL corresponds to the pitch and tooth profile, and the final letter S indicates a construction variant within the series. The number after the S, for example 400 or 800, refers to the belt width in hundredths of an inch. Thus, PHG 90-XL-S800 is an XL-profile belt with 90 teeth and 8 inches of width.
These belts are used in industries where synchronization and low backlash are required: automation, packaging, printing, textile, machine tools, and laboratory equipment. In Argentina they are found in precision conveyors, drive shafts, dosing systems, and indexing mechanisms. Their XL profile makes them suitable for light and medium drives, with small-diameter pulleys and exact drive ratios. They are also used in conditioning equipment and in special machines where space is limited.
To select correctly, take into account the number of teeth, the pitch, and the width required by your pulley. Check that the profile matches that of the pulley and that the belt length allows for the center distance. During installation, ensure pulley alignment to avoid uneven wear and noise. Tension must be the value recommended by the equipment manufacturer: a belt that is too tight overloads the bearings and a loose one jumps teeth. Periodically check the condition of the teeth and the presence of cracks.
SKF timing belts can be interchanged with other brands that use the same profile and pitch, as long as the number of teeth, width, and tooth type match. It is not enough for the length to be similar: the profile must be identical for it to mesh correctly. When replacing, compare the full designation and check whether the pulley accepts the new belt. At MR Accesorios Industriales we can advise you on the right equivalent according to your current belt part number.

Frequently Asked Questions
- What does the number after the S in the designation mean?
- The number after the S indicates the belt width in hundredths of an inch. For example, S400 corresponds to 4 inches of width and S800 to 8 inches. It is a key data point for the belt to fit correctly on the pulley.
- Can I replace an XL belt from another brand with an SKF PHG?
- Yes, as long as the XL profile, pitch, number of teeth, and width match. The full designation must be equivalent. If you have doubts, send us the original belt part number and we will help you verify interchangeability.
- How should I tension an XL timing belt?
- Tension must follow the equipment manufacturer's recommendation. In general, use the minimum tension that prevents tooth jump under load. A belt that is too tight wears the bearings and a loose one produces noise and irregular wear.
