Twin Screw Involute Spline Extruder Shafts Model 120 For Pet Food Compounding Usage
In addition to its load-bearing capabilities, this product is also heat-treated using vacuum quenching, which further enhances its strength and durability. This process hardens the material, making it more resistant to wear and tear, and less prone to failure.
The Involute Spine Shaft is an inner spline type, which makes it an ideal solution for applications requiring high-precision and accuracy. The spline teeth are designed to fit perfectly with other mating parts, ensuring a smooth and seamless operation.
This product is available in various lengths, ranging from 500mm to 15000mm, making it suitable for a wide range of applications. The center diameter of this product ranges from 15.6mm to 350mm and over, providing versatility and flexibility in its use.
