Types of Spline Shafts
Parallel Key Shaft
Parallel key shafts are known for their simplicity and efficiency. They are commonly used in gear and pulley systems.

Spline Shaft with Involute Spline
Involute spline shafts are renowned for their ability to distribute load evenly across all the teeth, reducing wear and tear and prolonging their lifespan.
Internal Spline Shaft
Internal spline shafts are designed with the splines on the inside of the shaft, making them ideal for applications where space is limited.
Non-circular Spline Shaft
Non-circular spline shafts are used in applications that require non-uniform motion transfer. They are often used in automotive and aerospace industries.
Choosing the Right Spline Shaft
Several factors come into play when choosing a spline shaft. These include Shaft Diameter, Spline Type, Number and Size of Splines, Shaft Length, Material, and Surface Treatment. Understanding these parameters can help you choose the right spline shaft for your needs.
