The INA 1.25" x 0.75" x 0.03" Thrust Bearing Washer is engineered to provide precise axial load distribution in needle roller thrust bearings. Designed for applications where the adjacent machine part is unhardened yet sufficiently rigid and geometrically accurate, this washer ensures optimal performance and longevity. Its through-hardened and polished steel construction offers enhanced durability and resistance to wear, making it a reliable choice for various industrial applications. The washer's unsealed closure design facilitates easy maintenance and lubrication, contributing to the overall efficiency of the bearing system. With an outside diameter of 1.25 inches, a bore diameter of 0.75 inches, and a thickness of 0.03 inches, the INA TWA1220 washer is compatible with the NTA-1220 bearing part number, ensuring seamless integration into existing systems. This washer is particularly suitable for use as shaft or housing locating washers, providing stability and support in axial load applications. Its lightweight design, weighing only 0.03 lbs, does not compromise its strength and reliability. The INA TWA1220 Thrust Bearing Washer is an essential component for maintaining the integrity and performance of needle roller thrust bearing assemblies, offering a cost-effective solution for industries requiring precise axial load management.
