Key Features
- OEM Dimensional Accuracy — Manufactured to Husqvarna's exact key width and depth tolerances, ensuring correct torque transfer between shaft and hub without slippage or play.
- Drop-In Replacement — Seats directly into the existing keyway slot with no filing or fitting required, restoring the drive connection to its original specification.
- Broad Saw Compatibility — Confirmed fitment for the TS70, MS360, and TS90 tile and masonry saws, covering a wide range of Husqvarna table saw applications.
- Restored Drive Integrity — A worn or missing parallel key causes blade shaft slippage and uneven cutting; replacing it with this component restores consistent, true blade rotation.
- Genuine Husqvarna Part — Supplied as an authentic OEM component, backed by Husqvarna's engineering standards for construction equipment.
A parallel key is a small but critical component that locks a rotating shaft to a hub, pulley, or blade flange, transmitting torque without allowing the two parts to rotate independently. In tile and masonry saws such as the TS70, MS360, and TS90, it ensures the blade drive shaft turns in precise unison with the drive assembly. When a parallel key shears, deforms, or works loose, the shaft can slip within the hub, leading to inconsistent blade speed, vibration, and loss of cutting accuracy — making prompt replacement with the correct OEM part essential for safe and effective operation.
