1623580: WASHER:THRST

**Product Description: Thrust Washers** - **General Description**: Thrust washers act as bearing surfaces in rotary applications, preventing axial movement along the shaft. They support axial loads and are typically used with thrust bearings. - **Materials**: Thrust washers can be made from various materials, including: - Case-hardened steel - Through-hardened steel - Stainless steel - Bronze (including phosphorous bronze) - Brass - Graphite (for high-temperature applications) - Plastic (for low-speed, light-load applications) - Rubber and lignum vitae (for water-lubricated bearings) - **Dimensions and Specifications**: Thrust washers come in standard thicknesses with different inside and outside diameters. Important factors include: - Flatness and parallelism requirements - Surface finish (often specified as 10 micro inches for smooth movement) - Heat treatment specifications for durability Custom sizes can be produced to meet specific application needs. - **Applications**: Common applications for thrust washers include: - Automotive engines - Transmissions - Power take-offs - Pumps - Axle assemblies - Motors and winches They are often used in high-wear environments where reliable performance is critical. - **Key Features**: - Cost-effective alternative to thrust bearings. - Can be used in single or stacked configurations based on power transmission requirements. - Designed for moderate-speed motion control applications, balancing performance and cost. - **Standards and Compliance**: Various organizations maintain standards for thrust washers, ensuring quality and compatibility across different applications. Notable standards include those from the International Organization for Standardization (ISO) and ASTM International. This overview provides insights into the functionality, materials, dimensions, applications, and standards associated with thrust washers, including detailed considerations for selecting the right model for specific needs.
