Description
Overview:
The Cup Spring is a genuine Husqvarna replacement part designed for walk‐behind lawn mowers, including LB 248S and LB 253S. Manufactured from durable spring steel, it uses a cupped (dish) profile to provide controlled axial tension within assemblies. This preload helps keep components tight under vibration, supports smooth operation, and contributes to a clean, even cut. Supplied under Husqvarna Manufacturer Part Number 503 33 25‐01 (503332501), it is engineered for a precise fit in the specified models. Suitable for routine maintenance and repairs, this cup spring restores correct tension where the original washer has worn, flattened, or corroded, helping extend the life of surrounding parts and fasteners. A practical, direct replacement for users maintaining domestic and professional mowers.
Key Features:
- Genuine Husqvarna part for assured compatibility and quality
- Robust spring steel construction resists fatigue and deformation
- Cupped profile delivers high load in a compact space for reliable preload
- Helps prevent loosening from vibration and maintains consistent alignment
- Supports smooth running of blade and drive-related assemblies
- Precise fitment to listed models reduces setup time
- Direct replacement for worn or distorted cup/spring washers
- Suitable for preventative maintenance and overhaul work
- Clean edges and correct dish height for repeatable clamping force
- Backed by Husqvarna's engineering standards for reliability
Typical Applications:
Used wherever controlled preload is required in mower assemblies, such as mounting interfaces that must stay tight under vibration. Commonly replaced during blade system servicing, deck refurbishments, or drive mechanism maintenance when the original cup spring shows wear, loss of tension, or corrosion.
