Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact dimensional specifications, ensuring the correct fit between mating components without slop or misalignment.
- Exact Shaft Engagement — Engineered to seat precisely in the keyway, transmitting torque correctly and preventing rotational slippage between the shaft and hub.
- PG820RC Compatibility — Confirmed fitment for the PG820RC planetary floor grinder, so you can order with confidence knowing this is the correct part for your machine.
- Restored Drive Integrity — A worn or damaged key allows components to slip under load, causing uneven grinding and accelerated wear; replacing it with this part restores full torque transmission.
- Verified Part Number — Cross-reference 574441101 against your PG820RC parts diagram to confirm the correct position before installation.
A key is a small but critical component that locks a rotating shaft to a hub, gear, or pulley, ensuring both turn together as a single unit. On a floor grinder like the PG820RC, the key transmits drive torque from the motor shaft to the driven component — if it shears, wears, or goes missing, the connection fails and the machine loses effective power transfer. Replacing a damaged key promptly prevents secondary damage to the keyway and surrounding components.
