Designed to accommodate heavy axial and moderate radial loads, the 29244 E spherical roller thrust bearing is suitable for self-aligning applications such as vertical pumps, ship propulsion shafts or mining crusher housings. Centralized lubrication grooves and drillings on the non-shaft washers ensure uniform grease distribution even in low-speed, high-torque conditions such as wind turbine yaw systems or tunnel boring machine thrust assemblies. Rated for 1,850 kN dynamic axial loads, operating in temperatures from -20°C to +120°C and equipped with optional nitrile rubber seals, the 29244 E effectively keeps out contaminants in harsh environments such as cement mixer drive hubs or offshore platform slewing bearings. The preload configuration reduces axial play to ≤0.1 mm, which is critical for precise positioning of heavy industrial robots.
