The SKF PHP SPA V-belt pulley is a power transmission component that mounts on a shaft and, with a belt, transfers motion between shafts. It suits industrial machines that need accurate speed ratios and reliable operation. MR Industrial Accessories supplies this brand and assists with pulley selection based on part number and application.
The part number breaks down into functional segments. PHP denotes the SKF V-belt pulley line. 3SPA specifies the profile and groove count: SPA profile with three grooves. 800 is the pitch diameter in millimeters. TB identifies the taper bushing type, and 5040 is the bushing size. For example, PHP 3SPA800TB5040 is a three-groove SPA pulley with an 800 mm pitch diameter and a 5040 taper bushing. Understanding this structure helps you order the correct replacement.
These pulleys appear in food processing, textile, wood, mining and aggregate operations. They drive fans, pumps, compressors, conveyors and mills, where V-belt drives provide flexibility and absorb vibration. They are common on production lines that require speed changes and on equipment where the taper bushing allows quick mounting and removal for maintenance.
When selecting a pulley, consider the belt profile (SPA, SPB, SPC), number of grooves, pitch diameter and bushing type. The TB taper bushing simplifies installation and removal without hammering. Verify alignment between pulleys to prevent uneven wear on the belt and grooves. The pulley itself does not require lubrication, but the condition of the shaft bearings does. Follow the manufacturer's instructions for bushing screw torque.
SKF PHP pulleys are interchangeable with other brands that use the same taper bushing system and belt profile. For a replacement, compare pitch diameter, number of grooves and bushing size. At MR Industrial Accessories, we can help you ensure the new pulley performs the same function as the original.

Frequently asked questions
- What does the part number PHP 3SPA800TB5040 indicate?
- PHP is the SKF V-belt pulley line. 3SPA means SPA profile with three grooves. 800 is the pitch diameter in millimeters. TB stands for taper bushing, and 5040 is the bushing size. This information lets you identify the pulley and order the right replacement.
- How do I choose the taper bushing for the pulley?
- The taper bushing must match the shaft diameter and the size specified in the pulley part number. Check the shaft dimensions and refer to the manufacturer's table. If unsure, send us the pulley part number and shaft diameter for guidance.
- Are SKF pulleys compatible with belts from other brands?
- Yes, as long as the belt has the same profile (SPA, SPB, SPC) and the number of grooves matches. Compatibility depends on the profile standard, not the belt brand. We still recommend checking groove condition and alignment before mounting.
