V-belt drives rely on pulleys to move power from one shaft to another, and the SKF PHP line covers this job across a broad range of machinery. Each pulley is built to accept a V-belt and to set the ratio the drive needs. MR Industrial Accessories supplies this line within its power transmission range for customers in the United States and Latin America.

Reading the code helps you order the right part. PHP is the SKF V-belt pulley category. The first figure tells you how many grooves the pulley has. The letter D gives the belt profile. The number that follows is the pitch diameter, measured in millimeters. TB refers to the bushing or mounting style. So PHP 4-D120TB is a four-groove pulley for a D-profile belt, pitch diameter 120 mm, mounted with a taper bushing. Other suffixes appear depending on the fastening system, so confirm the full code before you send it.

These pulleys show up in food, textile, wood and cement plants, as well as in aggregate processing. Industrial fans, compressors, centrifugal pumps and conveyors are common homes for them too. The V-profile carries high torque while absorbing vibration, which suits production lines that run hard and need little attention.

Selection comes down to a few inputs: the power being transmitted, the speed of the fast shaft and the ratio you want. The pitch diameter has to match the belt, and the groove count has to suit the power level. A taper bushing makes installation and centering easier. Line up the pulleys correctly, because misalignment wears belts and bearings early. The pulley itself takes no lubrication, though the bearings on the equipment do.

SKF PHP pulleys can be swapped with other brands that share the same taper bushing system and belt profile. On a replacement, compare pitch diameter, groove count and bushing type. If you are unsure, MR Industrial Accessories can point you to the equivalent pulley for your application.
