Washer 810W35613-0050 Sinotruk Sitrak

Product Introduction

Structure

This washer is a precision-machined annular component, crafted from high-strength, wear-resistant black polymer composite material (likely reinforced nylon or PEEK). It features a symmetrical design with four evenly spaced rectangular slots on its outer circumference, which are used for anti-rotation and torque transmission. The inner and outer diameters are precision-ground to tight tolerances, ensuring a perfect fit with mating components. The surface has a smooth, matte finish to reduce friction and enhance sealing performance.

Performance

The polymer composite material offers exceptional mechanical properties, including high tensile strength, excellent wear resistance, and superior chemical stability. It is resistant to oil, grease, and most automotive fluids, and maintains its structural integrity in temperatures ranging from -40°C to 150°C. The anti-rotation slots ensure the washer remains securely in place under dynamic loads, preventing misalignment and component failure. Its low-friction surface minimizes wear on mating parts, extending the service life of the entire assembly.

Core Function

1. Acts as a load-distributing element, evenly spreading clamping forces across mating surfaces to prevent localized stress concentrations and component deformation.

2. Serves as a wear-resistant spacer, reducing friction and wear between moving or clamped parts, such as in suspension or axle assemblies.

3. Provides anti-rotation functionality via its slotted design, preventing the washer and associated fasteners from rotating or loosening under vibration and dynamic loads.

4. Enhances the overall reliability and durability of heavy-duty truck components by protecting critical mating surfaces from premature wear and failure.
