33021-XL

The 33021-XL tapered roller bearing is a high-performance, single-row component engineered to handle intense radial and axial loads simultaneously. Featuring an inner diameter of 105mm, an outer diameter of 160mm, and a width of 43mm, this bearing belongs to the premium X-life (XL) series, which ensures significantly higher dynamic load ratings compared to standard designs. Its optimized raceway geometry and superior surface finish minimize internal friction and heat generation, making it an ideal choice for demanding environments like heavy-duty gearboxes, automotive wheel hubs, and industrial spindles where long-term reliability is non-negotiable.

Designed with a separable cup and cone structure, the 33021-XL simplifies installation and maintenance by allowing independent mounting of the inner and outer rings. This metric series bearing is constructed from high-quality through-hardened steel, providing exceptional fatigue resistance and dimensional stability under temperatures ranging from -30°C to 120°C. Whether used in construction machinery or power transmission systems, its robust sheet steel cage ensures precise roller guidance and optimal lubricant distribution. For applications requiring rigid shaft guidance, these bearings are frequently mounted in pairs to provide high-precision axial positioning and increased system stiffness.
