This drive shaft with side holes is a precision transmission component featuring radially cross-drilled holes used for coupling pins, locking set screws, shear pins or lubrication channels. The shaft transmits torque between connected assemblies while the side holes provide positive mechanical locking and easy service access.
The core of this product is its material and processing quality. We machine from certified steel bar stock — carbon steel, alloy steel or stainless — and hold side-hole position accuracy within ±0.05 mm, diameter tolerances down to ±0.01 mm and run-out within 0.02 mm. Side holes are deburred and chamfered so pins seat cleanly and the hole edges resist stress cracking.

| Model | Shaft Diameters (D1/D2) | Total Length | Side Holes | Other Features | Typical Use |
|---|---|---|---|---|---|
| DS-01 | Ø12 / Ø20 mm | 150 mm (est.) | 2 × Ø5 mm cross-drilled | Keyway, M8 thread | Small drive coupling |
| DS-02 | Ø16 / Ø25 mm | 220 mm (est.) | 4 × Ø6 mm radial holes | Spline, retaining groove | PTO drive |
| DS-03 | Ø20 / Ø30 mm | 300 mm (est.) | 2 × Ø8 mm through holes | Ground journals, keyway | Transmission shaft |
| DS-04 | Ø25 / Ø40 mm | 420 mm (est.) | 6 × Ø8 mm cross-drilled | Threaded ends, spline | Heavy-duty drive |
Radial holes are jig-located to ±0.05 mm and chamfered on both ends, giving pins and set screws a clean, crack-free seat for reliable torque lock.
CNC-hobbed splines and milled keyways with tight width tolerance transfer high torque without backlash or key deformation.
Bearing seats are cylindrical-ground to h6/g6 fits, Ra 0.4 µm for smooth rotation, low vibration and long service life.
Centre-ground shaft body with ≤0.02 mm run-out keeps connected components perfectly aligned at speed.
Optional carburizing, induction hardening or nitriding delivers a hard wear surface over a tough, shock-resistant core.
Stainless grades or zinc / nickel / chrome plating resist corrosion and wear, with polishing available for a premium finish.
Beyond carbon and alloy steel, our turning, drilling and milling lines handle a broad portfolio of materials, so the shaft can be matched to strength, corrosion, weight or cost requirements.
