The Husqvarna 502552101 Chain is a genuine OEM component designed for the PG680 and PG680RC floor grinders. Sourced directly from Husqvarna, this chain is manufactured to the exact specifications of the original, ensuring a direct, no-compromise replacement for the drive system on these machines. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Genuine OEM Link Geometry — Each link is manufactured to Husqvarna's exact pitch, width, and tensile specifications, maintaining proper engagement with the drive sprocket on the PG680 and PG680RC.
- Direct Drive System Replacement — This chain installs into the existing drive assembly without modification, restoring the mechanical connection between the motor and working components as originally designed.
- Confirmed Fitment for PG680 and PG680RC Floor Grinders — Cross-reference part number 502552101 against your parts diagram to confirm compatibility with your specific machine configuration.
- Restored Power Transmission — A correctly functioning chain delivers smooth, consistent torque transfer across the drive system, allowing the grinder to maintain steady head speed under load.
- Protects Downstream Components — A worn or stretched chain accelerates wear on the sprocket and adjacent drive components; replacing it with a correctly dimensioned OEM chain helps preserve the integrity of the broader drive assembly.
The chain in a floor grinder forms a critical link in the power transmission path, transferring rotational force from the drive motor to the grinding heads. As the chain wears, it stretches and loses proper engagement with the sprocket teeth, causing slippage, uneven grinding performance, and accelerated wear on surrounding components. Replacing a worn chain with a correctly specified OEM part restores full mechanical efficiency and prevents the progressive drivetrain damage that a loose or fatigued chain can cause.
