Ningbo Kent bearing factory is specialized in producing high-quality steel bearing and advanced processing technology. Our bearings are high precision, low friction, low noise, and strong wear resistance. Suitable for motors, automobiles, motorcycles, machinery, reducers, and other equipment. We provide a full range of models with stable quality, timely delivery.

A ball bearing is a type of rolling-element bearing equipped with precision steel balls between the inner ring and outer ring.

By adopting rolling friction instead of sliding friction, it effectively lowers operating resistance, heat generation and mechanical wear. It can bear combined radial and light axial loads, ensuring stable rotation and high running accuracy.

Various types are available, including deep groove ball bearings, angular contact ball bearings and miniature ball bearings, serving automotive, motorcycle, automation, electric tools, medical equipement, industrial, agriculture and mechanical transmission fields.

  Medical and Dental Industries

  Whether it is a dental handpiece or drill, a piece of lab equipment, diagnostic machine, pump, or laser, these and other high-precision instruments all demand flawless, high-quality bearings to ensure reliability. Choosing the right bearings supplier is essential to uphold the   standard of these instruments.

  Robotics and Automation

  Robot arm bearings, cam rollers, track rollers, and other components demand perfection for automated systems like printing machinery or production lines for electronics – devices that challenge the boundaries of accuracy. It’s crucial to source these parts from trusted ball bearing suppliers to ensure optimum performance.

  Electric Motors

  Due to their versatility, electric motors are utilized in various scenarios and must withstand different types of stress. Parts like roller bearings or deep groove ball bearings in motors need to guarantee reliability. This emphasizes the importance of collaborating with reputable ball bearings manufacturers for consistent quality.

  Machine Tool and Spindle Repair

  Many industries rely on high-precision tools that require regular maintenance and parts replacement. We offer various ready-to-install angular contact bearings, and the consultation and onsite technical support to assist you throughout the process. When you need to buy bearings for such critical applications, it’s vital to choose only the best.

  High Tech / High Performance
