INA TWD1220 Thrust Roller Bearing Washer, Open End, Inch, 3/4″ ID, 1-1/4″ OD, 1/8″ Width

Description

Product Overview

The INA TWD1220 thrust roller bearing washer is engineered for demanding industrial applications where precision and durability are paramount. Constructed from through‑hardened chromium steel, the washer offers superior resistance to deformation, wear, and corrosion, ensuring a long service life even under continuous heavy axial loads. Its open‑end design provides easy installation and compatibility with a wide range of axial needle roller bearing assemblies, particularly the INA TC‑series.

Key specifications include a 3/4″ inner diameter, 1-1/4″ outer diameter, and a 1/8″ width, delivering a compact yet robust solution for power transmission equipment. The washer’s dimensions (1 x 2 x 2 inches) and lightweight profile (0.48 ounces) make it suitable for space‑constrained environments while maintaining high load‑carrying capacity.

Usage

This thrust roller bearing washer excels in applications such as gearboxes, motor shafts, conveyor systems, and other machinery where axial forces need to be managed efficiently. It is especially valuable in setups where adjacent components cannot serve as raceways, allowing the washer to act as a dedicated bearing surface.

Engineers and maintenance professionals appreciate the washer’s ability to accommodate high rotational speeds without sacrificing accuracy. Its ground raceway minimizes vibration and noise, contributing to smoother operation of the entire system. Whether retrofitting existing equipment or designing new machinery, the INA TWD1220 provides a reliable foundation for axial load handling.
