31317

The 31317 tapered roller bearing is a premium metric-series component engineered for heavy-duty industrial environments where managing combined radial and axial loads is critical. With a standard dimension of 85mm x 180mm x 44.5mm, this single-row bearing stands out due to its steep contact angle, which significantly enhances its axial load-carrying capacity compared to standard tapered designs. Built from high-grade chrome steel and featuring a robust pressed steel cage, it ensures structural integrity under high-torque conditions. The separable "cup and cone" architecture simplifies the installation process, allowing maintenance teams to mount the inner and outer rings independently while fine-tuning internal clearance for optimal machine performance.

Designed for long-term reliability, the 31317 model excels in demanding applications such as heavy-duty transmissions, mining equipment, and large-scale gearboxes. Its optimized raceway geometry minimizes internal friction, which effectively reduces heat generation and extends the service life of both the lubricant and the bearing itself. Whether you are dealing with high-speed rotation or fluctuating thrust loads, this bearing provides the necessary rigidity and precision to prevent shaft deflection. It is a drop-in replacement for major brands like SKF, FAG, and Timken, meeting international ISO 492 tolerance standards to ensure seamless compatibility with existing mechanical systems.
