Steel A/C Compressor Clutch Pulley
Custom CNC Machining — From Your Drawing to Finished Parts
This Steel A/C Compressor Clutch Pulley is a precision power transmission component designed for automotive air conditioning systems, heavy‑duty truck AC units, and off‑highway vehicle climate control systems. It is manufactured by our in‑house CNC precision machining process. The use of 1020 low carbon steel provides an excellent balance of good formability, high surface hardness after case hardening, excellent machinability, and reliable performance under high‑speed rotation, belt tension, and cyclic engagement loads. The CNC machining process ensures tight dimensional tolerances, superior concentricity, precise groove profiles, and consistent surface finish — all critical for clutch pulleys requiring smooth belt tracking, minimal vibration, accurate electromagnetic clutch alignment, and long service life in demanding engine compartment environments.
Our one‑stop approach — covering material selection, CNC turning, CNC milling (for cooling holes), surface finishing (black oxide, phosphate coating, or zinc plating), optional heat treatment (carburizing & hardening), and engineered packing — delivers a ready‑to‑install clutch pulley that meets OEM specifications and withstands belt wear, torsional vibration, thermal cycling, moisture, and road contaminants.

Our Advantages
Technical Advantages
1
Raw material warehousing, sawing, CNC turning & milling (3/4/5-axis), wire EDM, surface grinding, surface treatment, and inspection — all centralized under one roof. No subcontracting for any process step. This vertical integration means we fully control lead time, multi-process sequencing, and final quality, turning bar stock, plate,profile, or forging blanks into ready-to-assemble components.
2
Before the first chip is cut, our engineering team reviews your drawing for machining feasibility. We provide feedback on tolerance stack-ups, tool access limitations, thread specifications, and suggestions to simplify complex features without compromising function. Combined with in-house CAM programming for multi-axis machines, we ensure efficient toolpaths and consistent output from part one to part ten thousand.
3
We specialize in components that demand tight tolerances (±0.005mm achievable), fine surface finishes (Ra 0.4µm and below), and complex geometries — such as shafts with keyways and threads, manifold blocks with intersecting bores, housings with multi-face machining, and precision fixtures themselves. Full inspection capability — CMM, height gauges, bore gauges, profilometer — ensures every feature on your drawing is verified and documented.

Material Advantages
1
Whether it's steel billet, aluminum block, extruded profile, or forging blank — all raw material is sourced from certified mills and forge shops. Every incoming batch arrives with mill test certificates and undergoes our receiving inspection (spectrometer verification, hardness check, dimensional confirmation) before entering production. No unverified material ever reaches the shop floor.
2
We handle the full spectrum of starting material forms and grades:
Steel block/billet: Carbon steels, alloy steels (4140, 4340, 40Cr), tool steels (H13, D2, SKD11), stainless steels (304, 316, 17-4PH, 2205)
Aluminum block/billet: 6061, 7075, 5083, 6082, and other wrought grades
Profiles/Extrusions: Aluminum profiles with custom cross-sections, cut to length and precision-machined on mating faces and mounting holes
Forging blanks: Closed-die steel and aluminum forgings, machined to final tolerance on functional surfaces while preserving forged grain flow for superior strength.

Material batch integrity is maintained from receiving to finished part — regardless of starting form. Heat numbers, mill certs, forging lot numbers, and profile batch codes are tracked through sawing, machining, inspection, and packing stages. For industries requiring full material traceability, we deliver a complete dossier linking the original material lot to every finished part and its inspection records.
Service Advantages
A dedicated project manager oversees the entire process — from design review to final delivery — ensuring efficient communication at every stage.
Quotations are typically provided within 24–48 hours. Production progress is updated regularly through photos and production data, with continuous customer feedback collection throughout the project.
Full batch traceability and 24-hour response to quality-related issues ensure reliable post-delivery support.
