Value to Customers

Operators of excavators and loaders know that crankshaft failure can stop a machine for days. This aftermarket DAEWOO DB58T crankshaft is produced with high-quality forged steel to withstand heavy cycles of load and torque. Journals are ground to Ra ≤0.4 µm-smooth enough to keep the oil film steady-then induction-hardened to HRC 52-58, 3-5 mm deep, so the skin resists wear while the core stays tough. Forged grain beats cast iron for fatigue life, and each DAEWOO DB58T crankshaft is spin-balanced to under 10 g·cm/kg, cutting vibration and saving the rest of the drivetrain. Less downtime, lower repair bills.
