Product Info

LCRB Crossed Roller Bearing — up to 60% lighter with a compact design. High rigidity, precision, and easy installation for robotics.

🔧 Lightweight Structure for High-Precision Rotation
In advanced automation and robotic systems, excessive bearing weight often increases motor load, reduces energy efficiency, and shortens machine life.
To overcome these challenges, IKO developed the LCRB (Lightweight Cross Roller Bearing) — engineered for strength, precision, and reduced mass.

💡 Press-Formed Ring Design
The LCRB adopts a press-formed ring structure, reducing bearing weight by up to 60% compared to conventional types.
Made from chrome-molybdenum steel with high hardness treatment, it provides exceptional rigidity and stability under combined radial, axial, and moment loads.

🔍 Key Features
- 60% lighter than standard models — reduces motor power consumption
- Flange-integrated design for easy bolt-on installation
- High rigidity and precision — supports up to 970 rpm rotation
- Operating temperature: -25°C to 120°C
- Compact housing size ideal for limited-space equipment

🧭 Applications
- Robotic arm joints and actuators
- Precision rotary and inspection tables
- Automated assembly systems
- Measuring and positioning instruments
