The XRA series ultra-thin crossed roller bearings are designed to meet the growing demand for precision and compact design. Traditional bearings often fall short in terms of size and weight, especially in applications such as robotic joints, collaborative robots, medical CT machines, and high-end automation equipment. Our XRA series addresses these challenges with an ultra-thin and lightweight design that can withstand high loads and achieve ultra-high precision.
These bearings are widely recognized for their high rigidity and ultra-high rotational accuracy, which is crucial for precision machinery requiring the highest possible motion accuracy. The unique cross-roller arrangement within the XRA series bearings supports radial, axial, and tilting moments simultaneously, significantly improving bearing rigidity.
Despite their ultra-thin construction, the XRA series bearings maintain a strong load capacity. Their roller-raceway linear contact design effectively distributes stress, ensuring stable and reliable operation under high loads and high-speed rotation. This makes them ideal for applications where performance and reliability are paramount.
