Key Features
- OEM-Matched Dimensional Accuracy — Manufactured to Husqvarna's exact tolerances, ensuring the shaft seats and rotates correctly within the assembly without play or misalignment.
- Direct Drop-In Replacement — Engineered to align with existing mounting points and mating components in the PG450 and HTC450, allowing straightforward installation during service.
- Compatible with PG450 and HTC450 Floor Grinders — Confirmed fitment for both the PG450 and HTC450 planetary floor grinder models, covering a widely used range of professional surface preparation equipment.
- Restored Drive Integrity — A correctly fitted shaft maintains proper power transfer through the grinding head assembly, keeping grinding pressure and disc rotation consistent across the work surface.
- Genuine Husqvarna OEM Component — Supplied as an authentic Husqvarna part, built from the same materials and to the same standards as the original, so performance matches the machine's design intent.
The shaft is a core rotating component within the floor grinder's drive assembly, transmitting torque from the motor to the grinding head or disc tooling. It must maintain precise concentricity and dimensional integrity to keep the grinding heads running true — any wear, bending, or damage to this component will introduce vibration, uneven disc wear, and inconsistent surface finish results. Replacing a worn or damaged shaft with a correctly spec'd OEM part restores smooth, balanced operation and protects surrounding bearings and drive components from secondary wear.
