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.

    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.

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.

    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.
