30320-XL

The 30320-XL tapered roller bearing is a premium single-row unit engineered for heavy-duty industrial environments where managing combined radial and axial loads is critical. As part of the X-life series, this bearing features an optimized internal geometry and refined raceway surfaces that significantly reduce friction and heat generation. With a 100mm bore, 215mm outside diameter, and a total width of 51.5mm, the 30320-XL provides exceptional rigidity and precise shaft guidance. Its separable design-comprised of the cone (inner ring) and cup (outer ring)-simplifies the mounting process and allows for individual lubrication and maintenance, ensuring long-term operational stability in high-torque applications.

Beyond its dimensional precision, the 30320-XL is built to excel under demanding conditions, offering a dynamic load rating of approximately 410kN and a limiting speed of up to 3,400 rpm. The "XL" designation signifies an enhanced service life, often exceeding standard 303 series bearings by up to 70% under identical working loads. This makes it a preferred choice for automotive transmissions, agricultural machinery, and heavy construction equipment where downtime must be minimized. Whether used in a face-to-face or back-to-back arrangement, this bearing delivers the durability required for high-stress axial thrust and radial forces, maintaining tight tolerances even in fluctuating temperature ranges from -30°C to +120°C.
