Large Drone Motor Bearings
In recent years, the domestic large drone industry including industrial-grade, agricultural plant protection, logistics transportation sectors has developed rapidly, and requirements for core components of power systems keep rising. Bearings are demanded to perform better in heavy-load impact resistance, dust resistance, wide-temperature-range operation and long service life.
Many drone manufacturers face common challenges. General bearings cannot adapt to high-speed rotation. Raceway fatigue spalling easily occurs under heavy load impact. Seal failure in dusty environments causes premature wear. Lubricating grease solidifies or leaks under extreme cold and high temperature conditions, eventually leading to flight failures or even drone crashes. In traditional supply channels, top international brands have long lead times and high prices, and struggle to meet small-and-medium batch customization demands. Domestic small and medium manufacturers lack stable product quality and consistent batch performance, failing to satisfy reliability requirements of high-end drones.
Ningbo Kent Bearing has focused on motor bearings for over 20 years. It is a potential specialized and sophisticated enterprise dedicated to the R&D and manufacturing of high-precision, low-noise ball bearings. The company has built a full-chain value delivery system featuring high-precision manufacturing, fast delivery and scenario-based customization. Targeting the core pain points of large drone motor bearings, we have developed special products suitable for high-demanding working conditions.
Four Major Advantages
✓
Extreme Condition Adaptation
Special heat treatment process improves the toughness of bearing rings to resist heavy-load impact. Non-contact special sealing rings are adopted for excellent dust resistance. It supports operation in a wide temperature range from -40℃ to +150℃ to meet the operation requirements in various harsh environments.
✓
Customization & Stable Supply
Parameters such as clearance, dimensions and grease can be customized according to customer requirements, and joint forward development is available. We have more than 20 automated production lines with an annual capacity of 30 million sets, enabling stable mass supply. The sampling cycle is only one week.
✓
High Reliability & Long Service Life
The products reach ZV4 quality grade and P5, P6 precision grades. Micron-level dimension control guarantees batch consistency. Optimized design reduces the friction coefficient to below 0.001, delivering a longer service life than standard bearings.
✓
Comprehensive After-sales Support
We provide original manufacturer service support and commit to responding to customer complaints within 48 hours. Material certificates and environmental compliance documents are supplied together with shipments to fully meet customers' supply chain audit requirements.
Against the industry trend of accelerated domestic substitution of high-end bearings, selecting a professional local bearing manufacturer enables you to obtain performance comparable to imported brands, along with flexible customization services and more competitive prices. Drawing on more than 20 years of technical accumulation, Kent Bearings delivers performance matching imported brands while cutting costs by 30%~50%. It helps drone manufacturers reduce procurement costs and shorten product R&D cycles, providing reliable support for your drone power systems.
