Core Product Lines for Robotics

1. Ultra-Thin Section Deep Groove Ball Bearings

• Series 617/618/619: Engineered for compact robotic joints and high-speed motion systems, these ultra-thin-walled bearings offer 30% higher rigidity and 20% reduced rotational torque compared to standard designs. Ideal for space-constrained robotic arms and precision grippers in electronics assembly.
• Series 16000: Combines lightweight construction with high load capacity (dynamic load rating up to 500 kgf), ensuring smooth, low-vibration operation in servo motors and robotic actuators.

2. Thin-Walled Angular Contact Ball Bearings

• Series 718/719: Supports combined radial and axial loads with contact angles optimized for rapid directional changes in robotic joints.
• Miniature Angular Contact Bearings: Micron-level precision (tolerances ±0.002mm) for delicate tasks like semiconductor assembly and medical device manipulation.

3. Crossed Roller Bearings

• Key Features: Zero backlash design for SCARA and Cartesian robots. Offers a 50% lower friction coefficient vs. traditional ball bearings.

4. High-Speed Cylindrical Roller Bearings

• Applications: Suitable for CNC spindles operating at 20,000 RPM+ and robotic motors requiring ISO 10816-3 vibration class ≤ 2.8 mm/s.

Robotics-Specific Engineering Advantages

✅ Precision Engineering:

• ABEC-9 certification ensures sub-micron dimensional stability.
• Hybrid ceramic bearings (Si3N4) suitable for temperatures up to +150°C and corrosion resistance.

✅ Dynamic Performance:

• Pre-lubricated for maintenance-free operation (L10 lifespan > 10,000 hours).
• Custom grease options for explosive/hazardous environments (ATEX compliant).

✅ Modular Design:

• Flange-mounted and hollow shaft configurations for rapid integration.
• OEM/ODM support with a 72-hour prototype turnaround.
