Original IKO Crossed Roller Bearing CRBH/CRBC/CRBT - High Rigidity for Robots

IKO (Nippon Thompson) is one of the world's four premier bearing brands and a true pioneer in crossed roller bearing technology. While reducers are the "muscles" of a robot, IKO crossed roller bearings serve as the "skeletal pivot points." By arranging cylindrical rollers alternately at right angles in a V-shaped groove, IKO achieves exceptional radial, axial, and moment load capacities. These bearings are the core guarantee for "rock-solid" positioning in humanoid robot waists, arm joints, and high-precision rotary tables.

Product Highlights

Extreme Integration & Space Saving: A single crossed roller bearing can replace two conventional radial bearings, drastically simplifying robot structural design and reducing joint volume.
Superior Rotational Accuracy: Precision grinding of rollers and raceways provides sub-micron level rotational runout control, ensuring absolute precision in robot end-positioning.
Simultaneous Multi-Directional Loading: The unique crossed arrangement allows the bearing to easily handle complex combinations of radial, axial, and tilting moment loads.
Super Slim Design (CRBT Series): With sectional heights as low as 5.5mm, it is the top choice for lightweight joint designs in modern humanoid robots.
High Rigidity & Torque Density: Even in small sizes, it provides incredible moment rigidity, preventing robot shaking under heavy loads or high-speed movement.
Exceptional Smoothness (Caged Types): The CRBC/CRBH series utilize cages to prevent friction between rollers, resulting in low frictional torque and excellent low-speed smoothness.

Core Parameter Table (Key Series)

Series	Structural Features	Precision Class	Min Bore (mm)	Typical Advantage	Typical Application
CRBH	Integrated Inner/Outer Ring	P5 / P4 / P2	20	Ultra-stable, High Speed	Robot Main Joints, RTs
CRBC	Separable Outer Ring	P5 / P4	30	Low Friction, Economic	Automated Indexing Tables
CRBT	Super Slim Type	P5	10	Extreme Space Saving	Humanoid Fingers/Wrists
CRBF	With Mounting Holes	P5 / P4	10	Simplified Assembly	Cobots, Medical Equipment
CRBS	Ultra-Small Section	P5	50	Large Bore-to-Size Ratio	Optical Instruments, Radars

Application Fields

Humanoid Robotics: High-load waist bearings, hip joints under multi-directional stress, and lightweight dexterous hand joints.
Industrial/Collaborative Robots: Main axis bearings (1st to 6th), SCARA robot bases, and AGV precision steering mechanisms.
Precision Machine Tools: 4th/5th axis rotary tables, spindle supports, and ATC tool magazine rotation.
Semiconductor Equipment: Wafer robots and AOI (Automated Optical Inspection) turntables.
High-End Medical Imaging: Large CT scan turntables and precision surgical robot joints.

Frequently Asked Questions

Q: What is the main advantage of IKO bearings compared to standard ball bearings?

A: Standard ball bearings struggle to handle massive tilting moments. IKO crossed roller bearings use line contact (not point contact) and a crossed structure to provide 3-5 times the rigidity in the same volume while handling loads from all directions.

Q: Are the IKO bearings you sell 100% genuine Japanese products?

A: Absolutely. We provide only original IKO products with original packaging, anti-counterfeit labels, and batch number verification. We understand the fatal impact of counterfeit parts on a robot's lifespan.

Q: Which series should I choose if my joint space is extremely confined?

A: We highly recommend the CRBT Series. It is the pinnacle of IKO's super-slim technology, with a sectional height of only 5.5mm, enabling extremely compact robot designs.

Q: What is the typical service life of these bearings?

A: Under rated loads and proper lubrication, IKO bearings are designed for a service life of 10,000 to 20,000+ hours. Their superior materials and heat treatment ensure a very low long-term failure rate.

Q: Do I need special tools for installation?

A: To maintain precision, we recommend using professional press-fitting tools and strictly following the bolt pre-tension requirements in the manual, especially for the CRBF series with mounting holes.

Q: What is the lead time for common models?

A: We maintain small stocks for common models like CRBH/CRBC (1-2 weeks). Large orders or super-slim CRBT models typically require an 8-12 week factory lead time.
