Involute Spline Shaft 58 MC Cold Rolling Shaft Spare Parts For Twin Screw Extruder
Involute Spline Shaft 58 MC Cold Rolling Shaft Spare Parts For Twin Screw Extruder
Product Description
The involute spline shaft is the form of mandrel splines used by all the twin screw extruders over the world. The standards of the spline are Chinese GB standard, German DIN5480 (or DIN5482) and Japanese standard. The design of the involute spline shaft can make the groove depth of the screw larger, and ensure the mandrel and extending the service life of the screw element at the same time. The short-tooth involute spline shaft is commonly used by famous brand factories at home and abroad. It has many teeth, high strength, uniform force, and long mandrel life.
Spline Shaft Manufacturer
As a specialized spline shaft manufacturer, Nanxiang has the sophisticated machinery, capacity and fully trained employees, to produce different kinds of involute splined shafts. Wide selection of splined shafts for sale, welcome to consult.

Trend
As twin screw extruders advance to higher speeds and greater torque, the demands on the strength, particularly thermal strength, and precision of the twin screw extruder shaft have significantly increased. Through extensive and meticulous research, our company employs imported pre-hardened alloy tool steel from Germany. Spline processing is executed using cold rolling techniques with advanced CNC equipment from Europe. Customer testing has verified that our products fully meet the performance and quality standards of similar high-end imported products.
