SKF SPC TB pulleys are components for power transmission using SPC-profile V-belts. They are used in systems that require high transmission capacity and moderate speeds, such as those found in Argentine industry. MR Accesorios Industriales sells this line as part of its power transmission offering.
The designation PHP 3SPC150TB is interpreted as follows: PHP identifies the SKF pulley line; 3 indicates the number of grooves; SPC is the V-belt profile according to standard; 150 is the pitch diameter in millimeters; and TB indicates the type of taper bushing (Taper Bushing) for mounting. Series examples, such as PHP 3SPC200TB or PHP 3SPC280TB, show the variation in diameter. This nomenclature allows you to select the right pulley according to the number of belts and the required diameter.
These pulleys are used in industrial applications that demand reliable power transmission, such as fans, centrifugal pumps, compressors, conveyors and machine tools. In Argentina, they are common in food, chemical and textile plants and in the metalworking sector. Their taper bushing design facilitates mounting and dismounting and allows adjustment on shafts of different sizes. Combining them with quality SPC belts ensures stable operation under continuous duty.
To select an SPC TB pulley, take into account the power to be transmitted, the shaft speed and the desired transmission ratio. Check that the pitch diameter is compatible with the SPC belt profile and that the number of grooves covers the number of belts required. The taper bushing must match the shaft diameter. During mounting, ensure pulley alignment to prevent uneven belt wear. Lubrication does not apply to pulleys, but it does to the equipment bearings. Check proper belt tension according to the manufacturer's recommendations.
As for equivalents, SKF SPC TB pulleys can be interchanged with other brands that follow the same SPC profile standard and taper bushing system, provided the critical dimensions match: pitch diameter, number of grooves and bushing type. We do not invent part numbers for other brands; if you need an equivalent, contact us with the original part number and we will advise you. Interchangeability depends on verifying the technical specifications in each case.
