IKO Ultra-Small Crossed Roller Bearings: Help Shrink Automated Equipment Designs
IKO designs and manufactures a variety of crossed roller bearings that can handle radial, thrust and moment loads at the same time. These compact bearings feature rollers crossed at right angles between inner and outer rings.
• Widely used in machine tools, industrial robots and medical equipment because of their high rotational accuracy.
• Roller guide options include a cage or separator as well as a full complement design. Both the cage and separator styles offer a small coefficient of friction for high-speed rotation. Full complement bearings handle heavy loads at low speeds.
• Sealed and open designs are available. Sealed bearings incorporate synthetic rubber seals to protect against dust, dirt and grease.
ULTRA-SMALL CROSSED ROLLER BEARINGS
When you need to incorporate a compact bearing into a space-constrained automated machine design, you may think you have to sacrifice precision. After all, if you have a complex or high-speed rotating load, it’s natural to look for a large bearing with solid construction that can provide good accuracy and rigidity. If you’re challenged by an automated or robotic machine design with limited space, it pays to give crossed roller bearings extra consideration. Crossed roller bearings are advanced products that are ideal for space-constrained automated machine designs. And, new crossed roller bearings from IKO International can deliver precise, repeatable motion and fit within the tight confines of your equipment.

Why IKO Ultra-Small Crossed Roller Bearings?
These are designed with the rollers alternately crossed at right angles to each other between inner and outer rings. This creates a greater contact surface to allow the bearing to handle heavy / complex loads from any direction, simultaneously.
Available Size OptionsStay Ahead of Automated Equipment’s Always-Reducing Size Requirements
Designers of automated equipment with high-speed or rotating, complex loads can obtain high rigidity and precision with a compact crossed roller bearing. IKO’s CRBT105A crossed roller bearing, which offers ultra-small dimensions, delivers greater rigidity than typically found in double-row angular contact ball-type bearings plus smooth rotation while helping designers stay ahead of ever-shrinking size requirements. With a 10 millimeter bore diameter, 21 millimeter outside diameter and a narrow width of 5 millimeters, this bearing occupies half the sectional area of rear-mounted, 45-degree contact angle single-row roller or ball-type bearings.
Despite its compact size, the CRBT105A offers rigidity up to four times greater than double-row angular contact ball-type bearings. This combination of small size and high rigidity makes the CRBT105A suitable for robots with articulating arms, and it also can find use in compact surveillance cameras because it can handle complex loads in all directions.
Additional features and specifications include:
• Separators between cylindrical rollers to provide smooth rotation
• Dynamic load rating of 1,120N and static load rating of 811N
• Small coefficient of friction for high-speed rotation
• Lightweight design
