CNC Rotary Table Bearing Comparison: Which Is More Stable—Crossed Roller Bearings or Traditional Rotary Table Bearings?

As a core component of precision machining equipment, the rotary table’s rotational accuracy and load-carrying capacity depend directly on the selection of its internal bearings. Although both crossed roller bearings and rotary‑table bearings are used for supporting rotary tables, they differ fundamentally in design philosophy, stiffness characteristics, and dynamic stability. Having long served the precision machinery sector, Jiuliang Bearings has observed that many engineers tend to confuse the application boundaries of these two bearing types during the selection process, leading to equipment vibration, reduced accuracy, and even premature failure.

How can the service life of crossed roller bearings be extended in high-dust environments?

Crossed roller bearings, as high-precision, high-rigidity rotary support components, are widely used in industrial robots, CNC machine tools, automated equipment, and other applications. In high-dust environments—such as mining, cement, metallurgy, and wood-processing industries—dust particles infiltrate every possible crevice; once they enter the bearing interior, they accelerate raceway wear, disrupt the lubrication regime, and cause seizing and failure, thereby significantly shortening the bearing’s service life.

Causes of Crossed Roller Bearing Fracture and Preventive Measures

2026-03-12

Causes of Crossed Roller Bearing Fracture and Preventive Measures

Fracture of crossed roller bearings is a severe failure mode that can lead to equipment downtime, collateral damage, and even safety incidents. Such fractures typically occur in the raceways, rolling elements, or cage and result from stress exceeding the material’s strength limit or from fatigue life exhaustion. A thorough understanding of fracture mechanisms and the implementation of preventive measures are essential for ensuring the safe operation of equipment. This paper systematically examines the causes of crossed roller bearing fractures and the corresponding preventive strategies.

Causes of Raceway Spalling in Crossed Roller Bearings and Corresponding Mitigation Measures

Raceway spalling is one of the failure modes of crossed roller bearings, characterized by flaky or pitted material loss on the raceway surface. This type of failure not only directly compromises the bearing’s geometric integrity—leading to increased equipment vibration, elevated noise levels, and reduced precision—but can also trigger cascading equipment malfunctions. Understanding the root causes of raceway spalling in crossed roller bearings and implementing proactive preventive and corrective measures is essential for ensuring the reliable operation of high‑precision machinery and extending the service life of the bearings.

Why are crossed roller bearings commonly used in robot joints?

Robotics is playing an increasingly vital role in modern industry and automation, and robot joints, as one of the core components of robots, directly influence the robot’s motion accuracy and payload capacity. Crossed roller bearings, owing to their distinctive structure and performance characteristics, have become an ideal choice for robot joints.
