Glyco A190/2 STD Thrust Washer – Crankshaft

The Glyco A190/2 STD Thrust Washer is a precision‑engineered component designed to provide reliable axial support and load distribution for the crankshaft in a wide range of automotive engines. Its robust construction, exact dimensional tolerances, and high‑temperature resistance make it an essential part for maintaining engine integrity and performance.

Key Functional Characteristics

• Axial Load Management: The washer’s flat, circular design distributes axial forces evenly across the crankshaft surface, preventing localized stress and potential wear.
• High‑Temperature Resistance: Manufactured from premium alloy steel, the component can withstand operating temperatures typical of modern internal combustion engines without deformation.
• Exact Dimensional Tolerances: The washer’s diameter and thickness are engineered to match the original equipment specifications, ensuring a perfect fit within the crankshaft assembly.
• Corrosion Protection: A specialized surface treatment provides long‑term resistance to oil, coolant, and other corrosive substances commonly found in engine environments.

Material Composition and Manufacturing Process

The Glyco A190/2 STD Thrust Washer is fabricated from a high‑strength alloy steel, typically ASTM A193 Grade 8, known for its excellent wear resistance and toughness. The manufacturing process involves:

1. Cold Rolling: The steel plate is cold rolled to achieve the required thickness and flatness.
2. Precision Cutting: CNC machining ensures the washer’s outer diameter and inner clearance match OEM specifications.
3. Heat Treatment: A controlled annealing cycle enhances the material’s hardness and fatigue resistance.
4. Surface Finishing: A chrome or nickel plating layer is applied to provide additional corrosion protection and a smooth operating surface.

Installation Guidelines

Proper installation of the Glyco A190/2 STD Thrust Washer is critical for optimal engine performance. Follow these steps:

1. Clean the Crankshaft Surface: Remove all oil, grease, and debris from the area where the washer will sit.
2. Position the Washer: Place the washer onto the crankshaft, ensuring it is centered and aligned with the bearing surfaces.
3. Secure with Fasteners: Tighten the associated bolts or studs to the manufacturer’s specified torque values, typically around 70–90 Nm, depending on the engine model.
4. Verify Alignment: Use a dial indicator or similar tool to confirm that the washer remains level and does not shift during operation.
