Crankshafts may experience increased hardness and bending (runout) as a result of high heat exposure and rapid cooling after failure, frequently surpassing OEM tolerance limits and inducing considerable stress.
At Royce Onsite Machining, we use specialised ceramic blankets to perform controlled crankpin annealing, a heat treatment process designed to reduce both hardness and runout. When combined with precision machining, this technique restores crankshafts to OEM standards.
Our annealing process can reduce hardness on crankpin by up to 300 HB, eliminating harmful excess hardness and significantly extending the lifespan of your crankshaft.
