YRT bearings are specifically designed for high-precision rotary tables and indexing systems, capable of simultaneously bearing radial loads, axial loads, and tilting moments. They are suitable for high-accuracy, heavy-load, and stable-rotation applications. Their integrated structure optimizes rigidity and rotational precision, making them ideal for equipment requiring precise positioning and continuous rotation, such as CNC machine tools, radar antennas, precision measuring instruments, and robotic rotary joints.

It can simultaneously bear radial forces, bidirectional axial forces, and overturning moments.
The double-row roller layout increases the anti-deformation ability by 5 times (compared to single-row bearings).
With the surface hardening treatment of GCr15 material, the L10 life is ≥ 30,000 hours.
Some turntable bearings come with an integrated angle measurement system,enabling high-precision angle measurement for precise positioning and measurement applications.
1. Machine Tool Rotary Tables
CNC Vertical Machining Centers: Used in the 4th and 5th axis rotary tables. When a heavy workpiece is mounted off-center, it creates a massive tilting moment. The YRT bearing resists this moment, ensuring the cutting tool produces an accurate part.
Indexing Tables: In high-precision indexing heads for milling, drilling, and grinding, where the table must lock into position with zero deflection under cutting forces.
Grinding Machine Rotary Tables: For producing perfectly flat and parallel surfaces on large workpieces.
2. Precision Measuring and Inspection Equipment
Coordinate Measuring Machines (CMM): The rotary table on a CMM must not introduce any error when rotating a part for inspection. The high accuracy and stiffness of a YRT bearing are essential.
Roundness and Form Testers: The bearing's own runout must be far less than the tolerances it is trying to measure.
3. Industrial Robots
Heavy-Duty Robot Rotating Bases: The base joint of a large articulated robot that must support the entire arm and payload while maintaining precise positioning.
Spot Welding Gun Rotators: Where high moment loads are encountered.
4. High-Precision Drives
Radar and Satellite Antenna Pedestals: For precise and stable positioning, especially in windy conditions that create moment loads.
Medical Imaging Systems: In rotating components of CT and MRI scanners where smooth, precise, and stable rotation is critical for image clarity.
