Official OEM Thermo King parts catalog entry for the Thermo King Washer-Belleville 558423, verified by PEAK Thermo King and West Texas Thermo King Texas, Utah, Wyoming, Washington, Oregon, serving all of the USA.
Built for Performance: The Thermo King Washer-Belleville 558423 delivers OEM-grade spring retention for Thermo King refrigeration systems, helping maintain bolt tension and secure assemblies under vibration and thermal cycling in transport refrigeration applications.
Product Overview
The Thermo King Washer-Belleville 558423 functions as a conical disc spring washer engineered to provide consistent axial preload in bolted joints. This component supports uptime and reliability for reefer trailers and refrigerated truck units by absorbing relaxation, vibration, and thermal expansion that can reduce clamp force over time.
Key Features & Customer Benefits
- OEM Thermo King Specification – Ensures precision fit and consistent service in Thermo King assemblies for dependable temperature control.
- Spring Retention Design – Maintains bolt preload to reduce loosening from vibration and thermal cycling for improved fleet uptime.
- Compact, Low-Profile Form – Delivers high load capacity in limited space, supporting efficient component packaging on reefer trailers.
- Corrosion-Resistant Options – Meets common OEM material expectations for longevity in transport refrigeration environments.
- Simple Replacement – Supports rapid maintenance during scheduled service to minimize downtime and return vehicles to revenue service fast.
Product Details
The Thermo King Washer-Belleville 558423 is an OEM-design disc spring washer used as a mechanical spring element within Thermo King transport refrigeration assemblies. It performs as a preload device in bolted connections, improving joint reliability for temperature-controlled fleets operating across West Texas and the Southwest.
Efficiency & Sustainability
By preserving bolt tension and reducing the need for repeat fastener adjustments, the Washer-Belleville 558423 supports operational efficiency and lowers lifecycle maintenance needs. Maintaining secure assemblies contributes to consistent temperature control across Thermo King refrigeration units, helping fleets optimize fuel-efficient cooling and reduce unnecessary service-related emissions. This part aligns with broader Thermo King initiatives for durable, compliant components used in Smart Reefer SR-4 and Precedent-series environments.
Installation & Maintenance Tips
Install using specified Thermo King fastener torque values and OEM hardware to ensure correct preload. Inspect Belleville washers during scheduled maintenance intervals and replace any washers showing deformation, corrosion, or loss of spring action. Use manufacturer-recommended clamps and retainers for secure fitment and consistent performance.
Real-World Applications
The Washer-Belleville 558423 serves reefer trailers, refrigerated trucks, and stationary transport refrigeration mounts where reliable axial force and vibration resistance matter. Fleets operating in Amarillo, Lubbock, Odessa, West Texas, and the Permian Basin rely on these components during heavy-duty operations and extended temperature-control runs.
Available for installation and service in Amarillo, Lubbock, Odessa, and throughout West Texas.
