Splined Slip hub and shaft
Reverse Engineering Upgrade: Splined Slip Hub Redesigned for Strength and Reliability
At OEM Dynamics, we specialise in delivering practical engineering solutions when original components fall short — whether due to wear, failure, or outdated design.
In this recent project, a customer supplied a splined slip hub and shaft assembly requiring reverse engineering. The original component featured a two-piece design joined by a weld.
Our engineering team redesigned the part not just to replicate the component, but to significantly improve it.
From Welded Assembly to One-Piece Design
Rather than reproducing the original design, we re-engineered the slip hub into a single-piece component. This eliminated the weld joint entirely, increasing structural integrity and reducing the risk of failure in demanding applications.
Precision Manufacturing Process
The new component was manufactured using a controlled, high-precision process:
- CNC turned from high-strength 4140 steel
- Internal spline cutting for accurate power transmission
- Nitriding process applied for surface hardness and wear resistance
This combination delivers a component capable of handling higher loads, improved durability, and extended service life.
The mating shaft was also machined from 4140 steel and a Nitriding process applied for surface hardness and wear resistance

Engineering Beyond Replacement
This project highlights a key advantage of OEM Dynamics’ aftermarket services — we don’t just replicate parts, we improve them.
By analysing the original design and understanding its limitations, we provide engineered upgrades that deliver long-term performance benefits.
