Shopper Award

The JUN crankshaft made from shaving has flexibility in a design as compared with a forge product. A crankshaft designer can determine form satisfactorily. The JUN BILLET CRANK SHAFT is a genuine crank shaft with both the counter weight of ideal form and the excellent balance.

Compatible with the Strength and the Lightness

    A crankshaft is part which receive bent vibration and twisted vibration by explosive pressure and return inertia force, therefore crankshaft should keep strength for corresponding these conditions. This matter should be especially needed in the tuned engine with high power. But improvement of strength becomes to decrease response of engine if to add more fat without consideration. Both strength and lightness are realized by performing stress analysis. SCM440 is used as a material and processing corresponding to the material is performed. It has both strength and lightness by giving heat treatment and a special surface treatment.
The Finishing Touches
    In order to rotate a crankshaft smoothly, the accuracy (The degree of a true circle, and surface roughness) of a pin journal becomes important. The crankshaft which polish finished pays careful attention to the degree of a true circle, the surface roughness, and transformation etc... and is wrapped. After a finishing surface treatment, it is wrapped and a friction loss is made into the minimum. Even if it is the weight form in which the rate of balance is excellent however, when the balance of the whole crankshaft is bad or bent, vibration occurs. Dynamic balance adjustment and bend correction were performed and the cause of vibration as much as possible is eliminated.
