Spline shafts — Hollow penetration shaft with small internal diameter

About this product

・Left-side spline pitch of 2.5 mm makes groove processing unnecessary for fitting ・Hollow φ12 diameter makes machining unnecessary

Automobiles must be able to drive quickly, cruise slowly, handle inclines, and more—and the engine cannot do it alone. That is where the transmission comes in. AIKOKU ALPHA produces five hundred thousand automotive shafts each month (not including pinion shafts used in power steering), and our components are used in 90% of auto transmissions. The transmission is critical to vehicle operation, and must be assembled from durable, high-precision parts. Particularly as cars get more compact and closer to net shape (where the final product approximates the design), AIKOKU ALPHA shafts are perfectly suited to the challenge.
