Powder Metallurgy Pulley

The metal pulley combines powder metallurgy and ball bearing technologies.  It uses iron-based powder as the base material and is manufactured through precision pressing, high-temperature sintering, and integrated bearing assembly processes. The metal pulley tooth profile, hub structure, and ball bearing are integrated into a single unit, eliminating the need for additional machining of adaptation interfaces and achieving integrated "transmission + support" functionality. The product combines the high precision and consistency of powder metallurgy with the low friction and high speed advantages of ball bearings. It features precise tooth meshing and smooth operation, making it suitable for medium-to-high speed and high-precision synchronous transmission applications. It is an efficient alternative to traditional "pulley + bearing" separate assembly solutions.

Product Feature And Application

The core advantages of producing powder metallurgy pulley using powder metallurgy technology are near-net-shape forming, integrated pulley tooth profile and hub structure, and significant advantages in cost, efficiency, and consistency under large-scale production.

（1）Outstanding material properties and long service life: The iron-based material, after blackening and anti-rust treatment as required, further enhances its corrosion resistance. The teeth, after sintering, are wear-resistant and durable, far exceeding the service life of ordinary machined parts.

（2）Integrated structure and strong adaptability: Different modules can be integrally formed according to customer drawings, while also integrating auxiliary structures such as shaft holes, keyways, locating steps, and chamfers. No subsequent secondary processing is required; it can be directly assembled with the equipment's shaft system, significantly simplifying the customer's assembly process and meeting the transmission and installation requirements of various types of powder metallurgy pulley.
