TRA 411 Precision Thrust Washer (Axial Bearing Component) - High Durability and Load Capacity | S Brand
The TRA 411 thrust washer is engineered specifically to serve as a critical component in the assembly of axial (thrust) cylindrical or needle roller bearings. Manufactured from high-purity, through-hardened bearing steel (typically SAE 52100 or equivalent), this washer provides an exceptionally hard and smooth raceway surface necessary for minimizing friction and wear under continuous heavy axial loads. Its precision-ground faces ensure strict parallelism, which is paramount for achieving uniform load distribution across the rolling elements, thereby preventing premature failure due to edge loading. The robust design and tight geometric tolerances make the TRA 411 ideal for demanding applications in gear drives, industrial pumps, hydraulic machinery, and heavy equipment where operational reliability is non-negotiable.
As a Senior Product Manager, I recommend the TRA 411 for operators seeking to maximize machine uptime and reduce total ownership costs (TCO). Its superior surface finish and material quality contribute directly to extended lubricant life and reduced heat generation, resulting in significantly longer maintenance intervals compared to standard thrust components. Integrating the S brand TRA 411 into your assemblies guarantees compatibility with high-speed environments and compliance with rigorous industrial quality standards (ISO 492). This component is a proactive investment in mechanical longevity, ensuring sustained performance even in environments characterized by shock loads and marginal lubrication.
