M 276449/410

The M 276449/410 single row tapered roller bearing is a robust solution meticulously designed to excel in applications requiring exceptional load handling and precise motion. With substantial dimensions, featuring a 536.575 mm bore, a 761.873 mm outer diameter, and a 146.05 mm total width, this bearing is built for heavy-duty performance. Weighing approximately 208 kg, its formidable structure is optimized to accommodate significant combined radial and axial loads simultaneously. This design, characterized by separable inner and outer rings, along with its specific contact angle of 12.5 degrees, ensures a true rolling action, minimizing friction and enabling a reference speed of 500 revolutions per minute, making it a reliable choice for critical industrial machinery.

Engineered for durability and operational efficiency, the M 276449/410 bearing offers a formidable basic dynamic load rating of 3,613 kN and a static load rating of 8,000 kN. Its precision-engineered tapered rollers and raceways facilitate optimal load distribution, effectively reducing stress peaks and enhancing resilience against misalignment or shaft deflection. This meticulous design promotes the formation of a hydrodynamic lubricant film, which significantly lowers friction, reduces operational heat, and extends the lifespan of both the lubricant and the bearing itself. The inherent rigidity, achievable when adjusted against a second tapered roller bearing, provides a highly stable and reliable bearing arrangement crucial for maintaining consistent performance in high-stress environments.

The M 276449/410 single row tapered roller bearing finds its indispensable role across a wide array of heavy-duty applications where reliability and endurance are paramount. Commonly integrated into automotive axle systems, industrial gearboxes, and transmissions, its ability to manage substantial combined loads makes it ideal for challenging conditions. Furthermore, it is a critical component in various construction equipment like excavators and cranes, robust mining machinery, and agricultural equipment such as tractors and harvesters. Its robust construction and high load-carrying capacity ensure extended service intervals and reduced maintenance needs, ultimately contributing to increased uptime and cost-efficiency in demanding operational scenarios.
