Cross roller bearings are high-precision rolling bearings engineered with a unique structure where cylindrical rollers are arranged crosswise at 90-degree angles between inner and outer rings. This innovative design delivers exceptional rigidity, high load-carrying capacity, and superior rotational accuracy, making them indispensable components for applications requiring stable performance under complex working conditions. As a professional wholesale supplier of cross roller bearings, we offer a full range of high-quality products that comply with international standards, catering to diverse industrial needs.
Our cross roller bearings are manufactured using premium high-carbon chromium bearing steel and stainless steel materials, combined with advanced precision forging, quenching heat treatment, and super-finishing processes. These stringent manufacturing procedures ensure the bearings achieve high hardness (up to HRC 62-65), excellent wear resistance, and corrosion resistance. The crosswise roller arrangement enables the bearings to withstand radial loads, axial loads, and moment loads simultaneously, eliminating the need for multiple bearing combinations and saving valuable installation space.
A key advantage of our cross roller bearings is their ultra-low friction coefficient and smooth rotational performance, which minimizes energy consumption and reduces operational noise (below 60dB). With high rotational accuracy (up to P5 class), they are ideal for high-precision equipment that demands minimal runout and deflection. Our product range covers various types of cross roller bearings, including outer ring split type, inner ring split type, and full complement type, with inner diameters ranging from 10mm to 500mm, fully meeting custom requirements for different equipment and working environments.
Cross roller bearings are widely used in a variety of high-precision and heavy-load industries. In the industrial automation sector, they are essential for industrial robots, robotic arms, and precision machine tools; in the aerospace and defense fields, they are applied in aircraft landing gear and radar systems; they also play a critical role in medical equipment (such as CT scanners), semiconductor manufacturing equipment, and heavy-duty industrial machinery. Whether in high-speed rotation, heavy-load operation, or precision positioning scenarios, our cross roller bearings maintain stable and reliable performance.
As a trusted wholesale supplier, we provide competitive pricing, sufficient inventory, and fast global delivery for cross roller bearings. We also offer tailored customization services, including special material selection, size modification, and sealing structure design, to address unique customer needs.
