SKF PHP-B-SH series V-belt pulleys are designed for B-section belt drives. They are used to build or replace drives in industrial machinery, transmitting power between shafts reliably. MR Industrial Accessories supplies this line to customers across the United States and Latin America.
The part number tells you the key specifications. PHP indicates the SKF V-belt pulley category. The first number is the number of grooves: for example, PHP 1-B34-SH has one groove, while PHP 2-B34-SH has two. The letter B specifies the belt section. The number after the hyphen is the pitch diameter in inches. The SH suffix means the pulley mounts with a taper bushing. The series includes diameters from 34 to 44 inches, with one or two grooves.
These pulleys suit B-belt drives in compressors, industrial fans, pumps, mills, conveyors, and machine tools. They are common in food, textile, and chemical plants, as well as maintenance shops that replace worn pulleys or assemble new drive lines. One or two grooves cover simple drives up to those needing more torque capacity or redundancy. As part of the SKF line, they are a known option for standardizing plant components.
When selecting a PHP-B-SH pulley, consider the required pitch diameter, the number of grooves for the power to be transmitted, and the SH bushing that matches your shaft diameter. During installation, clean the bushing taper and the bore, ensure grooves are free of burrs, and align pulleys precisely to avoid uneven belt wear. The pulley itself does not require lubrication, but the bushing may if the manufacturer specifies. Check belt tension according to the equipment manual.
When replacing a pulley, you may find equivalents from other brands that use the same taper bushing system and belt section. Codes can differ, but the critical factors are pitch diameter, number of grooves, and bushing type. At MR Industrial Accessories, we can help you identify the right replacement.
If you know the code of your SKF PHP-B-SH pulley, send it to us via WhatsApp or email for a quote. If you only have shaft and belt measurements, we can help you identify the replacement. MR supports workshops and plants throughout the United States and Latin America.

Frequently asked questions
- What does the SH suffix mean on these SKF pulleys?
- The SH suffix indicates a taper bushing mounting system. This allows a firm fit and easy disassembly without damaging the shaft or pulley. Select the SH bushing with the correct diameter for your shaft.
- Can I replace a pulley from another brand with an SKF PHP-B-SH?
- Often yes, if the belt section (B), pitch diameter, number of grooves, and bushing type match. Verify shaft dimensions and groove spacing. If unsure, contact us with the code or a photo.
- How do I choose between a one- or two-groove pulley?
- The number of grooves depends on the power to be transmitted and available space. A one-groove pulley suits simple drives; two grooves allow higher capacity or load sharing with two belts. Always follow the original equipment specifications.
