33030-XL

The 33030-XL is a high-performance single-row tapered roller bearing designed for metric applications requiring high precision and heavy load capacity. Featuring a 150mm bore, 225mm outside diameter, and a total width of 59mm, this unit follows the standard 330 series geometry with an optimized internal design. The "XL" (X-life) designation signifies a premium quality level with improved raceway surfaces and enhanced steel grade, providing a higher basic dynamic load rating of approximately 550 kN. Its separable design allows for the independent installation of the inner ring (cone) assembly and the outer ring (cup), significantly simplifying the mounting process and maintenance intervals in complex machinery.

Engineered for durability under extreme conditions, the 33030-XL bearing excels at managing combined radial and axial loads simultaneously. Thanks to its refined contact geometry, it minimizes internal friction and heat generation, which allows for higher limiting speeds-reaching up to 3,450 rpm in specific lubrication environments. This makes it an ideal choice for heavy-duty industrial gearboxes, automotive transmissions, and construction equipment where axial rigidity and long-term operational reliability are non-negotiable. When installed in pairs, these bearings provide a rigid shaft guidance system that effectively handles thrust in both directions, ensuring smooth performance even in high-vibration settings.
