As the global industry is rapidly upgrading towards high-precision, high-load, and long-cycle operation, bearings are the core and basic transmission components of all mechanical equipment. Their performance directly determines the operating efficiency, operation and maintenance costs, and service life of the entire equipment. It has also become one of the key components that restricts the application of many high-end equipment.
RDK bearings originating from Germany, relying on more than a hundred years of precision machinery manufacturing accumulation and strict process control standards across the entire chain, have now become a precision transmission solution commonly trusted by nearly 40 industrial fields around the world, providing reliable core component support for production upgrades in various industries.
The RDK brand was founded in Essen, a major industrial town in Germany, in 1913. It has been deeply involved in precision bearing R&D and manufacturing for more than a hundred years. Currently, it has deployed 8 intelligent production factories, 20 localized business service companies and 4 cutting-edge technology R&D centers in Germany. The global sales and service network covers more than 150 cities in more than 30 countries and regions, and can provide customized bearing products and technical services according to the special needs of different industries and different working conditions.
All factories under the brand implement globally unified quality control standards and always take “zero defective products” as the core production goal. While continuously improving production capacity to meet global market demand, they also integrate green production concepts throughout the entire production process, and have gained long-term recognition from global customers with stable and reliable product performance.
From large agricultural harvesters that operate continuously in the fields, to lifting engineering machinery that operates at high altitudes, to medical imaging equipment that requires extremely high operating accuracy, to high-end equipment manufacturing fields such as metallurgical mining, new energy wind power, passenger car manufacturing, and aerospace precision machine tools, RDK bearings can be seen everywhere.
Severe loads, high-speed operation requirements, and special dusty/high-corrosion environments in different application scenarios place extremely high requirements on bearing materials and production processes. RDK bearings can easily adapt to the use needs of various extreme working conditions with their hard-core product development and manufacturing capabilities.
On the product side, the core base materials of RDK bearings are all made of 100Cr6 high-carbon chromium bearing steel that meets the DN 17230 standard. This material has the characteristics of uniform hardness, strong wear resistance, and excellent toughness. It is not easy to deform during hot processing and installation, ensuring the basic performance of the bearing from the source.
At the same time, the product relies on the brand’s unique ultra-precision heat treatment process, high-precision steel ball processing technology and special lubrication structure design. It has the four core advantages of high speed, high hardness, low noise and long life. The friction loss during operation is extremely low, which can not only reduce the noise, heat and energy consumption during the operation of the equipment, but also significantly reduce the wear of other parts of the equipment, effectively reducing the risk of unplanned equipment downtime.
Whether it is the high-intensity continuous operation scenario required by heavy industrial equipment or the millimeter-level precision and smooth operation required by medical equipment, RDK Bearings always adheres to the detail control of German precision. Based on high-quality raw materials and top manufacturing processes, it continuously helps downstream customers reduce equipment operation and maintenance losses and improve production and operation efficiency. It lays a core foundation for the long-term and stable operation of machinery and equipment in various industries around the world, and also contributes in the field of core components to the digitalization and intelligent upgrade of global industry.
