Crossed roller bearings are engineered for high-precision applications, with dimensions conforming to ISO dimension series 18 as per DIN 616. They are composed of outer rings, inner rings, rolling elements, and plastic spacers. The outer ring is split and held together by three retaining rings. A unique feature of these bearings is the “X” arrangement of cylindrical rollers. This configuration allows them to support axial forces from both directions, radial forces, tilting moment loads, and any combination of these loads using a single bearing position. As a result, in many designs, two - bearing setups can be simplified to a single - bearing one. Crossed roller bearings are extremely rigid and offer high running accuracy. They are available with normal clearance, low clearance, or preload. Their outer rings can be easily fixed to adjacent structures using clamping rings. These bearings find applications in fields where precision and compactness are crucial, such as robotics, medical equipment, and semiconductor manufacturing, ensuring smooth and accurate rotational movements.
