Custom Herringbone Gear Shaft and Spline Shaft Export — Packing & Shipment by Henan Sankuang Machinery

Henan, China — Henan Sankuang Machinery Technology Co., Ltd., a leading Chinese manufacturer of industrial gears and gear shafts, has recently completed production and quality inspection for a batch of custom herringbone gear shafts, spline shafts and large-diameter gear shafts destined for overseas clients. The products are now being professionally packed in the workshop and are ready for shipment worldwide.

On the shop floor, more than a dozen large gear shafts are neatly arranged, each wrapped in multi-layer anti-rust and moisture-proof film over the tooth surfaces and journals, with thick cushioning at the ends. Export-grade wooden cases are prepared alongside, ensuring safe delivery during long ocean and inland transportation — a standard packaging process Sankuang follows for every export order.
