Bon Engineers supplies forged crankshafts made from 42CrMo alloy steel and carbon steel, engineered for automotive and industrial engine applications. These components are precision-machined to match OEM dimensional tolerances, with journal diameters and stroke lengths tailored to specific engine models. The material composition ensures high fatigue resistance and structural integrity under cyclic loading conditions typical in internal combustion engines.
The crankshafts are heat-treated to achieve a hardness range of 28-34 HRC, consistent with standard industry practices for medium-duty engine applications. Surface finishes on main and crank journals typically fall between 0.4 and 0.8 Ra micrometres, following ISO 1302 guidelines. Forged construction is preferred over cast alternatives for applications requiring higher tensile strength, and the absence of weld repairs or reconditioning is standard in this supplier's production process.
These crankshafts are sourced by manufacturers of passenger vehicles, light commercial trucks, and agricultural machinery, as well as aftermarket rebuilders in Southeast Asia, Africa, and Latin America. Packaging is done in protective corrugated cases with rust-inhibiting vapour phase inhibitors. Trade terms are negotiable, with FOB Rajkot and CIF common. Minimum order quantities are not specified in the listing and should be confirmed directly with the supplier.

Before placing an order, verify the material grade and heat treatment process with Bon Engineers. Request material test reports (MTRs) for each batch, confirming chemical composition per ASTM E415 and hardness values per Rockwell C scale. Confirm that the crankshafts are forged, not cast, and that journal dimensions match your engine specifications exactly. Do not accept components without traceable batch numbers.
Lead time is not specified and must be confirmed directly. Typical production cycles for forged crankshafts range from 4 to 8 weeks after order confirmation. Incoterms are negotiable, but FOB Rajkot is common. Payment terms often require 30% advance and 70% against shipping documents. Ensure the supplier provides a commercial invoice, packing list, and certificate of origin. Avoid payments via unsecured methods like Western Union.
Conduct pre-shipment inspection for surface defects, dimensional accuracy, and balance. Use a micrometer to verify journal diameters and a surface roughness gauge for finish. Confirm magnetic particle inspection reports are provided. Check packaging integrity and presence of VCI paper. Retain samples for incoming quality control. Document any deviations with photos and notify the supplier immediately to avoid acceptance of non-conforming lots.
