YRT Slewing Bearing for High Precision Rotary Applications

Precision rotary systems often face challenges such as vibration, 定位误差, and insufficient rigidity under combined loads. A standard bearing may fail to maintain accuracy when equipment requires continuous rotation with axial, 径向, 和倾斜力矩载荷. Slewing bearing solutions like the YRT series provide a reliable option for CNC rotary tables, 机器人技术, and medical imaging equipment.

Developed by XCCZC轴承, the YRT series rotary table bearing delivers high rigidity, 低跳动, and stable performance for demanding industrial applications. With more than 20 years of bearing manufacturing experience since 2002, XCCZC supports global customers with precision bearing solutions.

YRT Slewing Bearing Designed for Precision Rotary Tables

The YRT series is a high-precision rotary table bearing designed to handle complex loads while maintaining accurate positioning. Unlike conventional ball bearings, YRT bearings use a three-row roller structure to achieve higher stiffness and better load distribution.

Key specifications include:

• Precision Grade: ISO P4 and P2, with SP and UP ultra-precision options
• Inner Diameter Range: 50 mm–850 mm
• Outer Diameter Range: 80 mm–1090 mm
• Height Range: 20 mm–96 mm
• 材料: GCr15 bearing steel or case-hardened steel
• 润滑: Pre-filled grease lubrication with optional lubrication holes
• Mounting Design: Integrated mounting holes on inner and outer rings

This structure allows the YRT slewing bearing to support axial loads, 径向载荷, and tilting moments simultaneously, making it suitable for precision positioning equipment.

Why Choose XCCZC YRT Slewing Bearing Solutions

When you select a precision bearing supplier, 准确性, 耐用性, and engineering support directly affect equipment performance. XCCZC Bearing combines advanced production processes with strict quality control to provide stable bearing solutions.

High Rotational Accuracy and Low Runout

YRT bearings are manufactured for applications requiring repeatable positioning. Typical performance includes:

• Axial and radial runout ≤0.003 mm for standard precision grades
• High-precision versions reaching ≤0.0015 mm runout
• Smooth rotation for servo-driven rotary systems

These characteristics help CNC machining centers maintain machining accuracy during continuous indexing operations.

High Rigidity Under Combined Loads

The preloaded roller system minimizes internal clearance and reduces elastic deformation. Compared with standard deep groove ball bearings, YRT bearings provide stronger resistance against tilting moments.

Typical applications include:

• CNC rotary tables
• Grinding and milling equipment
• Industrial robots
• Direct-drive torque motor systems
• Precision measuring equipment
