As robotic automation advances, the demand for compact, high-precision slewing rings is growing. ZZ provides specialized slewing ring bearings for robotic arms, ensuring smooth and accurate motion in various industrial settings.
Unlike large crane slewing rings, robotic applications require lightweight, low-friction, and compact solutions that support high repeatability and low noise. Our bearings meet these criteria, making them ideal for:
- Welding robots
- Pick-and-place arms
- Palletizing robots
- Assembly line manipulators
- Medical and surgical robots
Key Features for Robotic Applications
- Compact Design: Outer diameters starting from 100mm
- High Precision: Tolerance up to P5 class
- Smooth Rotation: Low torque startup, minimal backlash
- Silent Operation: Ideal for labs and cleanroom environments
- Durability: Hardened raceways and optional corrosion-resistant coatings
ZZ slewing rings use crossed roller or four-point contact ball designs for optimal load handling in both axial and radial directions — perfect for multi-axis movement.
