6803 Deep Groove Ball Bearing 17x26x5mm ZZ for Electric Motors

Ball bearings are used to reduce friction during rotation and support various loads. It does this by using two or more tracks to accommodate the balls and transfer the weight of the load through the balls. Typically, one track sits in the hole and remains stationary while the other track is fixed in the rotating part. The system works simply because if the shaft is set on a rolling unit as opposed to freely rotating, there is less friction, allowing the surfaces to slide against each other.

Most small and medium-sized motors use rolling bearings. Large and medium-sized motors also use rolling bearings. Ball bearings (deep groove ball bearings) are used for the bearings at both ends of the small motor. Medium-sized motors use roller bearings at the load end (generally used for high load conditions), and ball bearings at the non-load end (but there are also opposite cases, such as 1050kW motors). Rolling bearings are lubricated with grease, but they are also lubricated with oil.

The company has an advanced assembly line and a complete quality inspection center, and has passed ISO9001: 2015 international quality management system certification. As an expert in the production of miniature deep groove ball bearings, our company has rich manufacturing experience. At present, we mainly manufacture bearings in the 608-6005, 628-6205, 6300-6305 model range, and can also meet the special customization needs of users.
