Samples to Batch

trial batches and repeat orders

A drive system does not fail because a catalog category is wrong. It fails when a shaft runs out, a gear tooth wears too early, a bushing does not fit, or a small part makes the whole assembly noisy. These are the parts YUBAO works on every day.

Core Product

Gear Shafts

Integrated shaft-and-gearparts for motors, reducersand compact driveassemblies.

Custom Machined Shafts

Drawing-based shafts machined around your critical fits and features.

Hollow Shafts

Lower rotating mass while preserving strength and alignment.

Welded Shafts

Joined sections, finish-machined as one accurate shaft.

Spline Shafts

Controlled spline fit for reliable torque transfer and positioning.

Worms & Worm Shafts

Precision tooth geometry for compact, smooth power transmission.

Shaft Sleeves

Controlled bores and diameters for dependable assembly fit.

Gear & Flange Parts

For high-ratio or self-locking drive structures where tooth contact & finish matter.
