9019456Q

The 9019456Q thrust roller bearing is engineered to withstand extreme axial loads (dynamic load rating 1,840 kN, static 6,750 kN) in high-demand applications such as wind turbine gearboxes, mining conveyor systems, and heavy-duty hydraulic presses. Its asymmetrical cylindrical rollers and hardened raceways (HRC 60-64) optimize load distribution, minimizing edge stress under misaligned conditions (up to 0.5° tolerance). The "Q" suffix indicates a reinforced polymer cage for enhanced thermal stability (operating range: -30°C to +150°C) and reduced friction at speeds up to 1,000 rpm with oil lubrication. Pre-coated with EP2 lithium soap grease, it resists water washout in humid or marine environments, aligning with ISO 199:2014 standards for industrial drivetrains. The bearing's precision-ground surfaces and 2-mm chrome plating on outer rings provide corrosion resistance in chemical processing or offshore rig equipment. Widely used in steel mill roll necks, tunnel boring machines, and construction crane slew rings, the 9019456Q ensures extended service intervals and reduced downtime in abrasive, high-shock environments.
