Four-groove sheave wheels and belt pulleys can be requested as custom gray-iron sand castings for automotive applications. Sizes follow the selected OEM drawing. Define the actual belt and shaft relationships so the pulley request describes the component needed by that drive arrangement.
Specify the four-groove working profile
Provide the groove geometry, pulley diameter and the relationships between the working profile and shaft interface. Identify the mating belt and required installed alignment. State the operating duty relevant to the selected design and the complete iron grade and condition required.
Define bore and mounting acceptance
Show the bore and mounting geometry with the locating references used to assess fit. Put dimensional limits and measurement conditions on the drawing. Explain which relationships are evaluated together for the pulley’s installed position within the automotive assembly.
Choose blasted coverage and sample checks
Shot blasting and sand blasting are named surface requests. Define the selected coverage and final condition, particularly where the surface meets a functional contact. Samples are offered; identify what the initial pulley must demonstrate in profile, fit and appearance.
- The minimum order quantity is negotiable.
- The stated 100% inspection needs agreed checks and records.
- Provide quantity and the controlling pulley revision.
- Record accepted material and dimensional changes with the part definition.
Keep repeat orders connected to the same belt, shaft and component-approval requirements.
