TIMKEN 355 A Tapered Roller Bearing Cup - High Capacity Outer Ring (90.488mm D)
The 355 A Tapered Roller Bearing Cup is the precision-engineered outer ring component essential for creating a complete single-row tapered bearing assembly (often paired with the 355 X cone). Manufactured by industry leader Timken, this cup is constructed from through-hardened, high-carbon chromium steel, offering superior resistance to shock loads and wear in critical applications. Its specific geometry ensures accurate roller path alignment and optimal load distribution across the contact surfaces, guaranteeing the high dynamic and static radial ratings necessary for demanding industrial operations. This component is crucial for managing heavy combined radial and thrust loads typically encountered in gear drives, automotive axles, and large industrial machinery.
Selecting the genuine 355 A cup ensures system integrity and minimizes unexpected downtime, directly impacting operational efficiency. Designed to perform reliably under severe operating conditions and temperature fluctuations, this outer ring maintains tight tolerances and stable performance throughout its service life. The cup's consistent quality and precise fit allow for easier installation and maintenance, reducing long-term total cost of ownership. Upgrade or replace worn races with this genuine component to restore original equipment performance and extend the lifespan of your critical rotating assets.
