· Product Overview
Introducing the YITECH CNC Machined Steel Spline Shaft, a high-precision mechanical component designed for reliable power transmission and secure rotational coupling. This steel spline shaft features a multi-toothed splined section on one end and a smooth cylindrical bore on the other, with a center hole for mounting or keying.
Crafted from high-strength alloy steel (45# steel or 40Cr), this component offers excellent durability, wear resistance, and torsional strength. The precision-machined splines ensure accurate engagement with mating parts such as hubs, gears, or couplings, making it ideal for applications requiring smooth torque transfer and precise alignment.
Whether you're building robotics, automotive systems, industrial machinery, or custom mechanical devices, YITECH’s spline shaft delivers performance, reliability, and professional-grade engineering.
