The XRT series cross tapered roller bearing was created to meet this demand. It innovatively arranges two sets of tapered rollers in a cross pattern and integrates them into an inner and outer ring structure, thus achieving outstanding performance that cannot be matched by traditional bearings.
The core advantages of XRT series cross-taped roller bearings lie in their high precision, high rigidity, and strong load-bearing capacity. The unique cross-shaped arrangement of rollers enables a single bearing to simultaneously withstand combined radial, axial, and overturning moment loads. This not only greatly simplifies mechanical design and reduces component count, but also significantly improves the overall operating accuracy and stability of the equipment. Whether facing high-speed rotation or heavy loads, XRT series bearings maintain excellent performance, ensuring long-term stable and reliable operation of the equipment.
