Answer from Ningbo Changshi: This question touches on a crucial aspect of selecting the right equipment for a job. A ball-bearing Swivel is designed with internal ball bearings that allow for smooth, low-friction rotation. This design excels at releasing rotational stress (torque) in lighter to medium-duty applications, such as pulling smaller cables, ropes, or fiber optic lines. They are known for their rapid, smooth rotation.

A thrust-bearing Swivel, on the other hand, is specifically engineered to handle high axial loads, meaning it is built to withstand immense pulling force. Its internal thrust bearing is designed to support the load of the cable puller, making it the superior choice for heavy-duty applications like pulling large conductors, power cables, or steel wire ropes.

At Ningbo Changshi, we offer a range of professional-grade thrust-bearing swivels designed for power line and electrical construction. Our swivels are crafted from high-strength forged steel and feature high-quality bearings to ensure durability and reliability under extreme tension, providing the essential protection needed for your valuable cables and equipment.
