Spline Shaft Spacer

The 510437 from General Pump is a specific replacement part designed to keep your pump running smoothly. The spline motor shaft spacer works as part of the flange/coupler for pumps in the Series 71 and Series 72 lineup. Because it's an OEM part, the spacer is compatible and will fit neatly into place during installation. Additionally, it will hold up well to the long-term rigors of usage and age. It's a useful addition to your cart if you happen to be running a General Pump Series 71 or Series 72 pump.

Features:

• Spline shaft spacer
• General Pump OEM part
• For Series 71 and Series 72 Pumps

What is the Difference Between a Spline and a Serration?

Splines and serrations are both used to transfer torque between components in mechanical systems, but they differ in design and application. A spline is a set of grooves or teeth on a shaft that mesh with corresponding features in a mating component, such as a hub, which allows for smooth torque transmission and alignment. The teeth on a spline are typically longer and more uniformly spaced than those on serrations, ensuring a higher load distribution across the surface area, which is advantageous for precision mechanical components. Moreover, splines are often used in applications requiring precise alignment and rotational symmetry, such as in robotics or automotive industries, where durability and compatibility are crucial. Serrations, on the other hand, have a more saw-like appearance with shorter, angled teeth, making them ideal for applications where gripping power is more critical than alignment. Due to their design, serrations are commonly found in locking mechanisms or where axial movement must be restricted, as they provide increased frictional resistance.
