Screw Shaft Diameter:

φ20 mm ~φ300 mm

Screw Shaft Properties:

Wear-resisting, 

Corrode-resisting, Durable

Screw shaft is key to pow transmission and ensure the extruder running smoothly. That's the reason why we do more tests on individual combination to meet the tolerance requirement.

We can provide the shaft with A40 material which has excellent toughness and mechanical property under high torque and high loading condition. We control accuracy strictly during processing to guarantee the shaft groove depth, groove spacing standard,surface smoothly and strong durable.

Lesun can supply standard screw shaft such as single key shaft, hexanthous shaft, involute spline shaft from many overseas extruder brands like Coperion, Leistritz, Berstorff, Toshiba, JSW, Kobe, APV, Maris etc.

Processing Characteristics of Screw Shaft:

1.Suitable suggestion on material to ensure extruder components performance and extend lifetime of products.
2.Professional technical team can provide surveying and mapping support.
3.All extruder screw elements are finished by CNC machine.
4.Sophisticated quality managment system ensure superior quality.

Shaft Spline Sizes

Though we are spline shaft stock manufacturer, Lesun offer custom shaft spline sizes to match with application. We can provide 1 3 4 20 spline shaft, 15 spline shaft, 18 spline shaft, 20 spline shaft, 22 spline shaft, 24 spline shaft, 36 spline shaft,  6 spline shaft stock and so on.
