Slotted Shaft

We take a φ10 mm, 40Cr material, HRC 35 slotted shaft as an example. The double shear failure load is ≥25 kN. This force is enough for excavator links or hydraulic cylinder ears. The outer diameter

Drilled Shaft

We take a φ10×50 mm drilled shaft with a φ3 mm hole as an example. We use a φ3 mm cotter pin. The axial pull-out force is ≥1.5 kN. We use a φ3×30 mm spring pin. The axial pull-out force is ≥2.5 kN.

Shaft Spacer Sleeve

We take a φ20×φ16×20 mm (OD×ID×length) spacer sleeve as an example. The outer diameter φ20 h7 is 20.000 to 19.985 mm. The inner diameter φ16 H8 is 16.000 to 16.027 mm. The length tolerance is ±0.1

Internal and External Threaded Copper Nut

We take an M8 outer / M6 inner brass nut as an example. The outer thread tightening torque is 15 N·m. The inner thread bolt torque is 10 N·m. The nut body does not deform or crack. Brass has an

Hot Melt Embossed Nut

We take an M5 brass hot melt nut embedded in PA66 plastic (10 mm hole depth) as an example. We follow UL 746C for testing. The axial pull-out force is ≥900 N. This is about 50% higher than the

Turned Precision Parts

Our machining precision can reach ±0.01 mm. Diameter tolerance of ±0.01 mm is our normal level. ±0.005 mm is our precision level. Concentricity is ≤0.03 mm. Surface roughness of Ra≤1.6 μm is normal.
