Unlike conventional deep groove ball bearings or tapered roller bearings, the most distinctive feature of the XRUA series is the 90° cross arrangement of the rollers inside. This unique structure allows a single bearing to simultaneously withstand radial forces, axial forces and tilting moments, which dramatically simplifies mechanical design and improves system rigidity and accuracy.
Our XRUA series cross roller slewing bearings are manufactured from high-quality bearing steel and undergo precision heat treatment and grinding processes to ensure high precision, long life and high reliability.
In order to better optimize the ranking, we need to highlight the core advantages and application value of XRUA series. The following keywords should be naturally incorporated into the content: high precision, high rigidity, high load bearing, compact design, long life, robot joints, medical equipment, CNC machine tools, rotary tables, precision optical equipment.
Extreme Precision and Rigidity: The cross-aligned roller structure eliminates elastic deformation within the bearing, providing extremely high rotational precision and rigidity. This makes the XRUA series the first choice for precision equipment such as rotary tables for CNC machine tools, industrial robot joints, and medical CT equipment that require precise motion control.
Outstanding Load Carrying Capability: The cross roller design allows it to withstand large radial, axial and tilting moments simultaneously to effectively cope with complex loading conditions. This is critical in automated equipment and heavy machinery.
Compact and lightweight design: The XRUA series features an ultra-thin wall construction, which provides a smaller cross-section and lower weight than conventional bearings. This compact design not only saves mounting space, but also reduces the overall weight of the equipment, making it especially suitable for space-critical robotics and precision optics.
Simplified Design and Installation: A single XRUA bearing can replace two or more conventional bearings, simplifying the design and assembly process for the user, reducing costs and minimizing potential points of failure.
