NODULAR CAST IRON CRANKSHAFTS

CAT nodular iron crankshafts are manufactured with modern vacuum casting process. The 80-60-06 nodular iron is the best material for crankshaft that exceeds OEM specification. The nodular iron microstructure consists of pearlite iron 80-90%, and graphite over grade 2 and grade 3 in iron. Every casting batch is analyzed with pearlite and graphite. The state-of-the-art CNC machine centers provide superior tolerance.

CAT nodular iron crankshafts incorporate these features:
- CNC machined to provide superior tolerance.
- All journals are micro polished to 5 RMS.
- OEM original journal radii for using of standard bearings.
- Larger chamfer at oil holes for better lubricating.
- Every crankshaft has been magnafluxed and ultrasonic tested.
- Every crankshaft has been fully dynamically balanced to original specification for immediate use.
- Every crankshaft has been surface oxidized blackened for rust resistance and hardness.
