Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's original specifications, delivering the exact dimensional tolerances required for a secure shaft engagement on early entry saws.
- Correct 3/4" Shaft Fit — Sized specifically for 3/4" shaft applications, this collar installs directly onto the shaft without modification, maintaining proper positional control of rotating components.
- Compatible with SoffCut Early Entry Saws — Verified fit for the SoffCut2500 and SoffCut5000, Husqvarna's purpose-built green-concrete cutting saws used for early entry joint work.
- Maintains Shaft Alignment — A correctly seated shaft collar holds drivetrain components in proper position, preventing axial movement that can lead to blade misalignment or premature wear on adjacent parts.
- Direct OEM Replacement — Replaces the worn or damaged original with a part sourced directly from Husqvarna, preserving the integrity of the machine's cutting system.
A shaft collar is a mechanical fastening component that clamps onto a rotating shaft to control the axial position of other parts — such as bearings, spacers, or drive components — within an assembly. On early entry saws like the SoffCut2500 and SoffCut5000, maintaining precise shaft positioning is critical to consistent blade depth and straight cutting performance on freshly poured concrete. When a shaft collar becomes worn, cracked, or loses its clamping grip, drivetrain components can shift during operation, causing uneven cuts, accelerated wear on surrounding parts, or loss of blade control.
