Our company has recently improved and upgraded miniature deep groove ball bearings. Compared with the original ones, the speed is higher, the noise is lower, and the life is longer. They are the best choice for all kinds of industrial equipment and small rotary motors!

Existing series:

623-629, 604-6000, 684-6805, 693-6903, 633-638

Main application areas: lithium batteries, brushless motors, printers, computer cooling fans, fingerprint locks, spirit levels, electric toothbrushes, fishing gear, doors and windows, fascia guns, baby carriages, toys.

Many industry partners mentioned that miniature deep groove ball bearings will face Invalidation problem in use.

The following is the solution summarized by our company JRZC for you to better enhance your sense of use!

About 40% of the failures of ball miniature bearings are caused by dust, dirt, debris contamination and corrosion. Pollution is usually caused by incorrect use and poor use environment. It can also cause torque and noise problems. Miniature bearing failure caused by environment and pollution can be prevented, and the cause of such failure can be determined by simple visual observation. As long as the use and installation are reasonable, the erosion of the miniature bearing is easy to avoid. The feature of erosion is that there are indentations on the raceway of the miniature bearing ring caused by impact load or incorrect installation. Erosion usually occurs when the load exceeds the yield limit of the material. If the installation is not correct so that a certain load traverses the miniature bearing ring, corrosion will also occur. The pressure pits on the miniature bearing ring can also generate noise, vibration and additional torque.
