SKF PHP V-belt pulleys with B-TB prefix are components for V-belt drives. They are used to transmit power between shafts efficiently and quietly in a wide variety of machines. MR Accesorios Industriales markets this line, with more than 80 years of experience in the field. If you need a pulley for B-section belts, this series is the right one.

The designation PHP …-B…TB is read as follows: PHP identifies the SKF V-belt pulley line; the first number indicates the number of grooves (for example, 1 for a single-groove pulley); B is the belt section it accepts; the next two digits correspond to the pitch diameter in inches; and TB indicates the bushing or mounting type. In examples such as PHP 1-B34TB or PHP 1-B48TB, the middle number (34, 36, 38…) indicates the diameter. Always verify the full part number to ensure compatibility with your belt and shaft.

These pulleys are used in industrial fans, compressors, centrifugal pumps, conveyors, mixers and machine tools. In the agro-industrial sector they appear in augers, bucket elevators and mills; in process plants, in pumping and air-conditioning equipment. Their B section is common in medium power applications, where a robust, low-maintenance drive is required. MR Accesorios Industriales markets them for replacement and new projects throughout the country.

To select correctly, take into account the pitch diameter, the number of grooves and the bushing type. The pulley must be aligned with the drive pulley to avoid uneven belt wear. Verify that the groove is clean and free of burrs. Lubrication does not apply to the pulley, but it does to the shaft bearings. If the pulley has a taper bushing, tighten the fastening screws to the recommended torque. Misalignment shortens belt life and causes vibration.

SKF pulleys from the PHP line are interchangeable with other brands that use the same designation system and belt section. When replacing, compare the pitch diameter, groove width and bushing type. Do not invent cross-references: if you have doubts, send us the original part number and we will help you find the right pulley. Interchangeability between brands depends on standardized dimensions, but it is always advisable to check the manufacturer's data sheet.
