Versatile for industrial robot applications

17 January 2022

ROBOTICS AND automated machinery applications require highly versatile bearings; not only must bearings carry diverse loads with high precision, robotic motion is also becoming more complex. Machine designers must also fit bearings into shrinking mechanisms such as articulating arms that position and rotate objects.

IKO International's crossed roller bearings are designed to make line-contact with the raceway surface to give high levels of rigidity and load handling ability
while minimising deformation and maximising accuracy. The same construction that enables heavy-duty performance also gives the versatility today’s robotic applications demand. For instance, IKO International’s crossed roller bearings are engineered to handle radial, thrust and moment loads at the same time, which makes them particularly suitable for applications with complex motion.

Among the wide range of IKO’s crossed roller bearings, customers can choose bearings with extra- high rigidity or satisfy restrictive space and weight requirements for robotic mechanisms that perform light-duty wrist and arm motion.

Here’s how IKO crossed roller bearings can help satisfy your specific industrial robot requirements:

When the application requires very high rigidity:

  • CRBH Series crossed roller bearings feature solid, non-separable inner and outer ring construction to easily achieve high rigidity and high accuracy without being affected by surrounding structures. Suitable for applications with medium to high rotational speeds, the bearings incorporate separators between the cylindrical rollers to provide smooth rotation.
  • CRBF Series bearings combine high rigidity, accuracy, and easy installation. Mounting holes allow them to be bolted quickly onto the assembly. This type also incorporates separators between the cylindrical rollers.

When the requirement is for high performance while occupying less space:

  • CRBS Series. These slim crossed roller bearings feature a small outside diameter compared to the inside diameter, plus a narrow width. These are available with a retainer, with separators or as a full-compliment internal construction.
  • CRBT Series super slim crossed roller bearings measure just 5.5 millimeters in sectional height and 5 millimeters in width to meet machine downsizing and lightweight requirements. Separators between the cylindrical rollers provide smooth rotation.

Robotic systems challenge machine designers with varying motion requirements that can include heavy or light-duty load handling as well as the ability to perform complex tasks in less space. IKO’s lineup of crossed roller bearings exhibit rigidity, smooth motion, and accuracy along with a choice of sizes and constructions to fit various rotating and positioning mechanisms. This versatility makes them well-suited for designers looking to address the diverse needs of today’s industrial robots.
