INA TWA3244 Thrust Bearing Washer Open End 2in ID 2-3/4in OD

Description

Product Overview

The INA TWA3244 thrust roller bearing washer is engineered to meet the demanding requirements of modern power‑transmission systems. Constructed from through‑hardened chromium steel, the washer offers exceptional resistance to wear, deformation, and corrosion, ensuring a long service life even in harsh industrial environments. Its open‑end design provides flexibility during assembly, allowing the washer to accommodate a range of shaft diameters while maintaining precise alignment. The component features a ground raceway that delivers superior running accuracy and reduced vibration at high rotational speeds, making it suitable for applications where precision and reliability are paramount.

Key specifications include a 2‑inch inner diameter, a 2‑3/4‑inch outer diameter, and a width of 1/32‑inch, dimensions that conform to standard INA TC‑series axial needle roller bearings. The compact form factor, combined with a robust material composition, enables the washer to support heavy axial loads without compromising performance. Package dimensions are 3 × 3 × 0.2 inches, weighing only 0.8 ounces, which simplifies inventory handling and reduces shipping costs.

Usage

This thrust washer excels in a variety of industrial settings, including machinery that requires precise axial positioning, such as gearboxes, motor assemblies, and conveyor systems. It is particularly valuable in scenarios where adjacent components cannot serve as raceways, a common limitation in compact or space‑constrained designs. The washer’s high‑strength chromium steel construction allows it to withstand the intense forces generated by heavy‑duty equipment, while the ground raceway ensures smooth operation at elevated speeds.

Engineers and maintenance professionals appreciate the ease of installation provided by the open‑end configuration, which eliminates the need for additional machining or custom fittings. The washer is compatible with a broad range of INA TC‑series bearings, making it a versatile choice for retrofits, upgrades, and new equipment builds. Its reliable performance under fluctuating temperature conditions and variable load cycles makes it an ideal component for automotive, aerospace, and manufacturing applications where downtime must be minimized.

FAQ

What types of bearings are compatible with the INA TWA3244 washer?

The washer is specifically designed for INA TC‑series axial needle roller bearings, but it can also be used with other compatible thrust roller bearings that share the same inner and outer diameter specifications. Engineers should verify the bearing’s load rating and dimensional tolerances to ensure optimal performance.

Can the washer be used in high‑temperature environments?

Yes. The through‑hardened chromium steel material retains its mechanical properties at elevated temperatures, making the washer suitable for applications where operating temperatures may exceed typical ambient conditions. However, it is recommended to consult the bearing manufacturer’s temperature limits for the complete assembly.

How does the ground raceway improve performance compared to an unground raceway?

A ground raceway provides a smoother surface finish, which reduces friction and wear during operation. This results in higher rotational speeds, lower heat generation, and increased accuracy of the bearing assembly. In contrast, an unground raceway may cause higher vibration and reduced efficiency, especially under heavy loads.

What support is available if I encounter installation issues?

Our technical support team is available to assist with installation queries, offering step‑by‑step guidance, CAD drawings, and troubleshooting tips. Customers can reach out via phone, email, or our online portal, and we also provide a comprehensive installation manual that outlines best practices for aligning and securing the washer within the bearing assembly.

Is there a warranty for the INA TWA3244 washer?

Yes. The washer comes with a standard one‑year limited warranty covering material defects and manufacturing errors. Should any issues arise within the warranty period, we will evaluate the situation and provide a replacement or repair in accordance with our warranty policy.
