Rotary Table Bearings – The “Joint” That Defines Your CNC Machine’s Performance
In the world of CNC machining, the rotary table is where precision happens. And at the heart of every high-performance rotary table lies a bearing that must simultaneously handle radial loads, axial thrust, and tilting moments—all while delivering smooth, backlash-free rotation with positioning accuracy measured in arc-seconds.
That bearing is the rotary table bearing.
Global demand reflects its importance. The global rotary table bearing market is projected to reach approximately US$1.5 billion by 2033, growing at a CAGR of 5.8% from 2025 to 2033, driven primarily by increasing automation in manufacturing processes and technological advancements in bearing materials and designs.
Luoyang Ouna Bearing has established itself as a competitive player in this space, offering the comprehensive ORT series rotary table bearings including:
ORT standard rotary table bearings – For general high-precision applications
ORTS high-speed rotary table bearings – Designed for high rotational speed requirements
OKLDF bidirectional thrust angular contact ball bearings – For applications requiring precise bidirectional axial load handling
ORTM rotary table bearings with integrated measuring system – For real-time positioning feedback
What distinguishes our products is their ability to achieve P5, P4 and P2 precision grades across outer diameters from φ20mm to φ2500mm. We serve industries ranging from five-axis machining centers and CNC grinding machines to direct drive motors and precision measuring instruments.
Moreover, the broader trend of import substitution in China‘s high-end bearing market is creating new opportunities for qualified local manufacturers. Industry data shows that the localization rate for high-end bearings in China reached 41% in 2025, up from just 25% in 2020—representing a major breakthrough in the industry‘s ability to compete with foreign brands in premium applications. For international buyers, this means access to world-class quality at more competitive price points.
Whether you need standard ORT bearings or custom-designed solutions, Ouna Bearing is ready to support your precision motion requirements.
