Description
SKF PHP 3-C50-SD belongs to drive pulley, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for PHP 3-C50-SD and any equivalents.
SKF PHP-SD pulleys are V-belt drive components that mount on shafts using a split taper bushing. They transmit power between parallel shafts in industrial equipment, offering straightforward installation and removal with a secure fit. MR Industrial Accessories supplies this line as part of its power transmission range, alongside belts, housings, and bearings.
The part number reveals key specifications. In PHP 3-C50-SD, the 3 stands for three belt grooves, C50 is the pitch diameter in inches, and SD denotes the taper bushing that locks the pulley to the shaft. Similarly, PHP 4-C55-SD has four grooves and a C55 pitch diameter. Understanding this coding helps you replace an existing pulley accurately.
These pulleys are found in industrial fans, centrifugal pumps, screw compressors, conveyor belts, and machine tools. They are common in food, textile, and chemical plants, as well as maintenance workshops where worn pulleys are replaced or transmission ratios are changed. Pairing them with V-belts of the correct profile creates a complete drive system for various power and speed requirements.
For proper selection, confirm the belt profile (SPZ, SPA, SPB, or SPC), the number of grooves, the pitch diameter, and the acceptable bushing range. Install the taper bushing clean and dry, without lubricant on the taper, and tighten to the manufacturer's recommended torque. Align pulleys to prevent uneven belt wear and vibration. In dusty or humid environments, consider guards or surface-treated pulleys.
SKF pulleys interchange with other brands when standardized dimensions and belt profiles match, provided the pitch diameter, groove count, and bushing type are the same. Since fastening systems vary, compare the bushing and shaft bore before replacing. MR Industrial Accessories can advise on equivalents to keep your drive running.

Frequently asked questions
- How do I identify the pulley I need?
- Provide the full part number, such as PHP 3-C50-SD, or the equipment data: number of grooves, pitch diameter, belt profile, and bushing type. With that, we can quote the correct pulley.
- What does the SD suffix in the designation mean?
- The SD suffix indicates the type of taper bushing the pulley uses to mount on the shaft. It must match the shaft bore and the existing fastening system.
- Are SKF pulleys compatible with other brands?
- In general, they are interchangeable if the pitch diameter, number of grooves, and bushing type match. We recommend verifying the bushing and shaft before replacing.
