Description
SKF PHP 10-C140-J.MA 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 10-C140-J.MA and any equivalents.
The SKF PHP-C-J.MA series V-belt pulley is a power transmission component that mounts on a shaft and accepts V-belts. It transfers motion between parallel shafts in many types of industrial machinery. The metal body and standardized groove work with the belt to keep the drive running steadily. MR Industrial Accessories supplies this pulley as part of its power transmission range.
Reading the code helps you identify the pulley. The first three letters, PHP, mark the SKF V-belt pulley family. A number then gives either the pitch diameter or the groove count, depending on the specific code. The letter C shows the belt profile, here profile C. The number after C is the number of grooves or the outside diameter, and J.MA is a manufacturing or mounting variant. For instance, PHP 10-C140-J.MA means a PHP-series pulley with 10 grooves, profile C, diameter 140, in the J.MA version.
These pulleys appear in food, wood, textile, chemical and process plants where shafts must turn at fixed speed ratios. You also find them on ventilation units, centrifugal pumps, screw compressors, conveyors and machine tools. In milling, meat processing and packaging operations, V-belt drives are chosen for their flexibility and ability to absorb vibration.
When selecting a pulley, check the belt profile, the groove count needed for the power, the pitch diameter that gives the right peripheral speed, and how it mounts on the shaft. Make sure the keyway and fastening method fit the shaft. During installation, align the pulleys to prevent uneven belt wear and noise. The pulley itself needs no lubrication, but the shaft bearings do. Check belt tension and groove condition at regular intervals.
SKF V-belt pulleys can replace those from other makers that use the same dimensional and profile standards. The pitch diameter, groove count, belt profile and bushing or mounting type must all match. A similar code is not enough; compare the critical dimensions. If you are unsure, send us the details or the old pulley and we will help you find a suitable equivalent from the brands we carry.

Frequently asked questions
- What does the J.MA suffix mean on the SKF pulley?
- J.MA identifies a construction variant in the PHP series. It can indicate the bushing type, a finish, or a dimensional change. Send us the full part number and we will confirm what that version includes.
- How do I determine the number of grooves my pulley needs?
- The groove count depends on the power to transmit and the belt section. More power usually means more grooves or a larger diameter. Share your motor data and target ratio with us and we will help you size the pulley.
- Can I use an SKF pulley in place of another brand?
- Yes, if the belt profile, pitch diameter, groove count and mounting type are the same. Dimensional standards allow interchange between brands. Send the measurements of your current pulley and we will advise on the SKF equivalent.
