Cross roller bearings, also known as crossed roller bearings, are a type of rolling bearing that utilizes cylindrical rollers arranged perpendicular to each other to achieve high load capacity and rotational accuracy. They are commonly used in applications that demand heavy loads, precise movement, and minimal friction, such as machine tools, robotics, and medical equipment.
High Load Capacity: Cross roller bearings can withstand both radial and axial loads, making them suitable for applications with heavy and complex load conditions.
Precision Movement: The orthogonal arrangement of rollers eliminates skewing and tilting, resulting in smooth and precise rotation with minimal vibration.
Compact Design: Cross roller bearings have a compact design that allows for space optimization in applications where size constraints are a concern.
Long Service Life: The use of high-quality materials and optimized design ensures extended bearing life, reducing maintenance costs and downtime.
Feature | Benefit |
