This is the harmonic reducer roller bearing we recently designed and customized for a German customer for use in industrial robots; this bearing has the following features:
VKUKEN® was founded in 2000. We focus on the R&D, design, production and sales of precision bearings. We select the highest quality bearing steel, stainless steel and ceramic materials and develop more than 10,000 products. We can produce bearings with an inner diameter of Φ20mm-Φ6000mm. Products are widely used in dozens of fields such as household appliances, power tools, aircraft, drones, robots, fitness equipment, gearboxes, medical care, vehicle equipment, wind power equipment, elevators, etc.; today our products have been exported to the United States and Canada , Mexico, Europe, Japan, Germany, South Korea, the Middle East and more than 90 countries and regions; it has formed close cooperative relationships with brand companies in multiple fields.
At VKUKEN, quality is regarded as the foundation for the survival of the enterprise. You can see that we carefully measure every step from raw material inspection, process inspection, semi-finished product inspection, and finished product inspection. We use the ERP management system to supervise the production process of each order.
Bearings are widely used, but they are also affected by many factors. Many equipment equipped with bearings work in harsh environments for a long time; for example: construction machinery, agricultural equipment, textile machinery, steelmaking equipment, etc. Bearings may be exposed to sediment during work. , high temperature, contaminated liquid, dust, etc., these factors will affect the quality of bearings. To this end, our company has established a professional laboratory and introduced the world’s most famous testing equipment from Germany, Sweden, Japan, etc., to Each batch of goods undergoes extreme testing to ensure zero defects. Below are some of our testing equipment.
The German Leica microscope is used to detect carbide strips, meshes, liquids and inclusions in the raw materials. Heat treatment: annealing, quenching and tempering structure to ensure that the material structure is qualified and the service life of the bearings is ensured.
Under a given cyclic load, the maximum load that the bearing can withstand, including parameters such as load at failure, fatigue failure mode, fatigue strength, displacement and temperature, record all data during the test to ensure the safety and stability of the bearing.
In some industries, bearings will be exposed to corrosive gases or liquids during work. In order to ensure that our bearings work normally and will not rust in special industries, our laboratory will conduct anti-corrosion testing on the bearings.
Monitoring the vibration and noise of bearings is a key indicator to judge the quality of bearings. We have introduced multiple vibration meters from SKF, which can intelligently diagnose defects in bearing parts by measuring vibration and sound to ensure that we deliver Every batch of goods is zero defective.
We are an ISO9001、ISO14001 certified bearing manufacturer, and our products have also obtained UL, CE, TS16949, ROHS, REACH and other certifications.

Hi, I am Maxwell, I am an engineer in the field of bearing applications. I majored in mechanical and electromechanical engineering during college. After graduation, I worked for the top three "SKF" bearing companies in the world for ten years , during which I went to dozens of customers in different industries to help them solve problems in bearing applications; later I joined VKUKEN Bearing Manufacturing, and I will share bearing technical knowledge on this website from time to time. If you are a customer Please contact me to help you solve your problem; if you are also a technical expert in bearings, I am very willing to exchange technical knowledge about bearings with you.
Ball screw bearing types include angular contact ball bearings, deep groove ball bearings, thrust ball bearings, and cylindrical roller bearings. The proper configuration involves using a fixed support at the
Precision transmission bearings include angular contact ball bearings, cylindrical and tapered roller bearings, crossed roller bearings, thrust bearings, and needle bearings—each designed for high-speed, high-rigidity, and low-runout performance. Different industries
Complete failure of angular contact ball bearings can be identified by loud noise, increased vibration, rising temperatures, lubricant leakage, irregular shaft movement, and visible internal damage. These symptoms indicate critical
Inferior or expired lubricants can cause bearing overheating, increased friction, Corrosion and Rust, accelerated wear, Accelerated Surface Fatigue and Spalling, Lubricant Oxidation and Acid Formation, Contamination and Particle Intrusion, and
To select magnetic suspension protective bearings, you must evaluate rotor drop speed, shock load resistance, operating temperature, material compatibility, and structural fit. The ideal bearing should withstand emergency impacts during
Rolling bearings need to be preloaded to eliminate internal clearance, improve rotational accuracy, increase rigidity, reduce vibration, extend bearing life, and prevent bearing loosening during operation. Preload ensures that rolling
To install CNC milling machine bearings, first identify the correct bearing type—such as angular contact ball bearings or tapered roller bearings—and ensure the installation direction matches the load requirements. Use
The speed of a machine tool spindle bearing is affected by factors such as bearing type, preload, lubrication method, bearing clearance, shaft balancing, cooling system, and installation accuracy. To ensure
On the road of technological breakthrough, our company has never forgotten its original intention. Although we still have a certain gap compared with internationally renowned bearing brands such as NTN, SKF, FAG, KOYO, etc., we have achieved very good results in the past 20 years. Our bearings have replaced many international brands in many industries. In the future, we will continue to conquer leading technologies.
