Key Features
- OEM-Spec Bore Tolerance — Manufactured to Husqvarna's exact 1/2-inch internal diameter specification, ensuring a secure, wobble-free grip on the shaft without slippage or play.
- Drop-In Shaft Replacement — Matches the original collar's dimensions and set screw configuration for a straightforward swap on compatible Husqvarna floor saws and tile & masonry saws.
- Broad Fitment Across Two Machine Families — Compatible with FS-series floor saws (FS4800D, FS3500E, FS4600G) and TS/MS-series tile & masonry saws (TS250X, TS250XL, TS510, TS510G, MS510, MS510G).
- Shaft Position Integrity — A properly seated set collar locks rotating or sliding components at the correct axial position; a worn or failed collar allows shaft migration that can lead to misalignment and accelerated component wear.
- Genuine Husqvarna OEM Part — Sourced directly from Husqvarna's construction equipment parts program, this collar meets the same material and dimensional standards as the original production component.
A set collar is a mechanical fastener that clamps onto a shaft to fix the position of adjacent components such as bearings, pulleys, or blades. By securing the shaft against axial movement, it ensures that driven components stay in proper alignment during operation. When a set collar loosens or wears, the secured component can shift along the shaft, leading to vibration, uneven cutting, and premature wear on surrounding parts — making timely replacement essential for maintaining cut quality and machine longevity.
