In the fields of high-end CNC machine tools, industrial robots, and precision radar systems, the accuracy of slewing bearings directly determines the machining quality and positioning stability of the end equipment. For a long time, high-end demand within this niche market has been largely monopolized by brands from Europe, the US, and Japan. Recently...

For equipment such as aerial work platforms, cranes, and fire-fighting aerial ladders, the self-locking performance of the slewing system is directly linked to the safety of the operating personnel. Under hovering conditions, if the slewing drive experiences even minute slippage—often referred to as "boom drift"—due to hydraulic fluctuations or gear tooth wear...

In high-temperature industrial environments—such as metallurgical continuous casting operations, glass manufacturing, and cement kilns—equipment is frequently exposed to ambient temperatures of 200°C or even higher for extended periods...

Gear surface contact fatigue is one of the primary factors limiting the service life of slewing bearings. This is particularly true in the operating environments of heavy machinery—characterized by frequent start-stops and exposure to impact loads—where gear surface spalling often leads to the premature scrapping of the entire component...

As the last fully loaded heavy-duty truck slowly rolled out of the ZZ Bearings Industrial Park gates, the company successfully completed the on-schedule delivery of a complete order of specialized slewing bearings for gantry cranes...

In an era where aerial work equipment is rapidly evolving toward electrification and intelligent automation, the collaborative R&D of core components has become particularly critical. Recently...

The field of defense research and development pursues a near-perfect standard for component reliability, as even the slightest malfunction can lead to the failure of an entire system. Recently, a defense research institute provided feedback offering high praise for the ZZ high-precision...

Guided by the national "Dual Carbon" strategy, hydrogen energy—serving as a vital medium for clean energy—is rapidly gaining traction within the transportation and heavy industry sectors...

Spring returns to the land, bringing with it a renewal of all things. On March 12, marked by a ceremonial ribbon-cutting, ZZ Bearings officially announced the commencement of operations at its Phase II Smart Factory...

"Quality is the lifeline of an enterprise; bearings are the joints of machinery—there is no room for even the slightest negligence." This slogan hangs in the most prominent location within ZZ Bearings' production...

When it comes to bearing quality, the material accounts for seventy percent. To ensure absolute stability and traceability in raw material quality—thereby controlling product quality...

The slewing drive is a gearbox that can safely hold radial and axial loads, as well as transmit a torque for rotating. The rotation can be in a single axis, or in multiple axes together...

The first step is the design phase of the slewing bearing.Advanced calculation techniques attuned to slewing bearings guarantee an economic and safe dimensioning of load transmitting...

Slewing bearings are widely used in cranes, aerial work vehicles, roadheaders, excavators, and propagation machinery. However, there are so many...
