IKO Crossed Roller Bearings (CRB)

As modern robotics and automated machines perform more tasks than ever, bearings that enable complex motion and effective load handling are making it all possible. For example, many robots and cobots incorporate articulating arms to move, position or rotate heavy objects or perform routine tasks like welding and assembly. And, as robot functionality demands increase, design sizes continually shrink. Crossed Roller Bearings deliver precise, repeatable motion and can handle large axial, radial, and moment loads simultaneously to perform complex tasks. They also fit within the tight confines of today’s robots and cobots.

Crossed roller bearings feature a unique design in which the rollers are alternately crossed at right angles to each other between inner and outer rings. This arrangement creates greater contact with the raceways to allow the bearing to handle heavy or complex loads from any direction at the same time. The orthogonal array of rollers gives crossed roller bearings their compact size for space-constrained designs.

Here are just some of the benefits they offer robotic systems:

• Greater rotational accuracy
• Exceptional load handling
• Space savings
• Easy installation and handling
• Efficiency
• Long life and quiet operation

Meet a Diversity of Robotic System Requirements
Designers of robotics systems must answer demands for more functionality, load capability, and complex, yet accurate motion. Crossed roller bearings are constructed to position heavy loads with precision, and certain design elements can deliver even greater rigidity, accuracy, and mounting ease for
challenging applications. IKO International’s crossed roller bearing lineup comes in a variety of sizes and designs to deliver a broad range of benefits to optimize performance for a host of robotic systems.
