SKF PHP drive pulleys transfer motion between shafts in belt-driven equipment. They suit industrial drives where speed changes and torque transmission are needed, and MR Industrial Accessories LLC supplies them to maintenance and purchasing teams across the United States and Latin America.
The part number tells you most of what you need. Take PHP 1-3V800-SDS: one groove, 3V belt profile, 8.00 inches pitch diameter. PHP 2-5V465-SDS is a two-groove pulley for a 5V belt with a 4.65-inch pitch diameter. In both cases the SDS ending identifies the shaft mounting method: a split taper bushing, which lets you mount and remove the pulley without special tools.
Typical installations include fans, pumps, compressors, conveyors and machine tools in sectors such as food processing, textiles, woodworking, mining and oil. The drive absorbs shocks and vibrations, handles overloads and works in dusty or humid conditions when the right materials and coatings are chosen.
When selecting a V-belt pulley, check the power to be transmitted, the rotation speed, the target transmission ratio and the space available. During installation, confirm pulley alignment, correct belt tension and the condition of the grooves. Belts are not lubricated; shaft bearings are. Keeping contaminants out through proper sealing and protection helps the assembly last.
For interchangeability, SKF pulleys in this series can replace other brands that follow the same standardized belt profiles and pitch diameters. Verify the bushing dimensions and the mounting type before substituting. Codes differ between manufacturers, but dimensional standards make replacement possible. Ask a specialist to confirm the exact equivalent.

Frequently asked questions
- What does the SDS suffix mean on SKF pulleys?
- SDS indicates a split taper bushing for shaft mounting. It allows straightforward assembly and disassembly without special tools and provides firm, centered clamping.
- How do I choose the number of grooves for a V-belt pulley?
- The number of grooves depends on the power to be transmitted and how many belts are required. Higher power usually calls for more grooves. Check the manufacturer tables or ask our team for selection help.
- Are SKF pulleys compatible with belts from other brands?
- Yes, as long as the belts meet the standardized profile (3V, 5V, etc.) and the matching dimensions. Interchangeability follows international standards, but verify groove condition and belt tension.
