    10-27 2026
    For companies serving the bearing industry, participation in the China International Industry Fair offers a relevant setting to connect industrial innovation with global trade. Bearings are essential components in machinery and equipment, supporting motion and helping systems operate reliably. Their role links them closely to the fair's industrial focus, where manufacturers and industry professionals can explore products, technologies, and business opportunities across sectors. The event provides a platform for companies to showcase bearing-related products, exchange information, and build connections with potential partners. By connecting the China International Industry Fair's industrial environment with the needs of global trade, bearing products are more visible to international audiences. The fair brings industry participants together, while the platform supports communication and commercial engagement. Together, these elements create a practical context for presenting bearing businesses to the world.

  • Common Motor Bearings for Planetary Reducer Manufacturers
    10-23 2026
          Overview   In industrial robots, planetary gear reducers perform the core function of speed reduction and torque increase. The transmission accuracy, rigidity and service life of a reducer depend not only on the gears, but also on those inconspicuous bearings inside.     Bearings serve as the first support at the input end of the reducer. For bearing manufacturers supplying planetary gear reducers and servo motors, the product lines are highly concentrated on deep groove ball bearings and angular contact ball bearings. Among them, deep groove ball bearings are the most widely used "main force", and are the most common type for the drive end and non-drive end of small and medium-sized servo motors.     ·Advantages: low friction coefficient, high limiting speed, low noise, controllable cost;     ·Upgrade direction: To meet the low-noise requirements for robot-grade applications, silent-grade steel balls are normally adopted, the raceway curvature radius is optimized, and low-noise long-service-life grease is filled;     ·Kent Practice: 6000/6200/6300 series deep groove ball bearings are Kent’s main models matched for servo motors. P6/P5 accuracy classes are available. Contact and non-contact rubber seals come as standard, suitable for the input support position of most small and medium-sized precision planetary gear reducers. 1. Specialized Division of Labor, Each Leveraging Its Strengths       Reducer manufacturers focus on gear meshing design, housing machining and assembly processes. They entrust the core support components at the motor input end to professional bearing manufacturers for customized production — a sign of a mature industrial robot industrial chain.     Kent Bearing has 20 years of in-depth experience in the field of deep groove ball bearings. Fully automatic production lines enable full-process control from steel ball sorting, raceway superfinishing to seal assembly. We optimize internal parameters according to the specific working conditions of reducer manufacturers, delivering better practical solutions than general standard parts. 2. From "Standard Parts" to Customization   A qualified bearing supplier does not merely conduct spot goods trading, but participates in customers’ front-end design. Kent Bearing can select bearing models or provide non-standard customization based on the reducer input bore diameter and shafting force model. We optimize the raceway curvature radius, steel ball diameter and cage structure, and cooperate with customers on life verification (L10 calculation) and bench test validation. 3. Domestic Substitution Is Accelerating       In the past, bearings for precision servo motors relied heavily on imported brands such as NSK, SKF and FAG. Today, professional domestic bearing manufacturers represented by C&U Bearings, HCH Bearing and Kent Bearing have gradually met robot-grade matching standards in precision class, vibration & noise performance, service life and reliability. For reducer manufacturers, the adoption of domestic precision bearings brings the following benefits:    ·Lower procurement cost: typically a 20%~40% price advantage over imported brands;    ·Shorter lead time: reduced from 8–12 weeks for sea freight to 2–3 weeks for local delivery;    ·Faster custom response: barrier-free technical communication, modification cycles measured in days;    ·Supply chain security: free from disruptions caused by international logistics and geopolitical policies.         The competition for accuracy in robot reducers appears to be a contest of gears and housings, but fundamentally it is a systematic competition involving bearings, materials and manufacturing processes. If you are a reducer or servo motor manufacturer troubled by the accuracy, noise, service life or lead time of input-end bearings, please contact the Kent technical service team at 86-19957451956. Kent Bearing’s engineering team can support you with selection calculation, life verification and small-batch custom validation.
  • CIIF2026 China International Industry Fair with bearings
    10-20 2026
    The 2026 China International Industry Fair (CIIF) offers a significant platform for examining the role of bearings in modern industry. As essential components in machinery and equipment, bearings support motion, reduce friction, and contribute to reliable operation across industrial applications. Their performance can influence efficiency, service life, and maintenance requirements, making bearing technology an important consideration for manufacturers and engineering professionals. CIIF brings together industrial technologies and participants, creating opportunities to explore developments relevant to manufacturing. Within this setting, bearings connect component-level innovation with broader priorities such as equipment reliability and production performance.Visitors can consider how bearing solutions fit into machinery systems and how technical requirements vary according to operating conditions and application needs. For companies involved in bearing production, distribution, or use, the fair can provide a venue for professional exchange and industry engagement. Discussions around product capabilities, engineering needs, and manufacturing applications may help participants identify areas for cooperation and further evaluation. The event also offers a broader view of how specialized components contribute to industrial systems.   As the 2026 edition approaches, CIIF provides a timely opportunity to focus on bearings as a foundational element of industrial equipment. By bringing attention to component technologies alongside wider manufacturing developments, the fair underscores the importance of dependable, application-appropriate bearing solutions in supporting industrial operations.   Any question pls feel free contact me: Web: www.bgbearing.com  Email:info@bgbearing.com Mobile/whatsapp/wechat: +86-19957426729
