Pulley engineering review points
Quotation depends on the controlled drawing and application, not on the gallery image alone.
Quality control- Drive geometry
- Groove profile, pitch diameter, number of grooves and belt system.
- Hub interface
- Bore, taper bush, keyway, fasteners and mating shaft.
- Material
- Required grade or applicable standard, confirmed for the duty.
- Machining
- Bore, keyway, faces, groove surfaces, runout and drawing tolerances.
- Verification
- Critical dimensions, material records and any project-specific balance or runout requirement.

Common sourcing questions
Can Hongsen review a pulley from an existing sample?
Yes. A drawing is preferred, but sample photos and measured information can start a discussion. Final manufacturing still requires controlled technical data.
Which pulley profiles are shown in the Hongsen catalog?
The catalog includes SPZ, SPA, SPB and SPC V-groove profile tables, along with taper-lock and other pulley examples.
Can casting and machining be reviewed together?
Yes. Bore, keyway, faces, grooves, runout and inspection expectations should be included in the RFQ.
Are the model numbers on this page stock items?
They are catalog examples. Availability, dimensions and commercial terms are confirmed against the requested model or customer drawing.
