RC Bearings

In many remote control models, whether rc model cars or rc model aircraft, rc bearings are the indispensable main transmission components. Some rc bearings are used on servers, some on wheels, and some on micro motors. All parts that need to be driven are inseparable from the rc bearings, so the quality of the rc bearings will largely determine the overall quality, service life and experience of the remote control model.
    Founded in 2007, Zhangzhou Runstar Bearings Manufacturing Co ltd is a professional rc bearings manufacturer, we have been committed to the design and production of rc bearings with high precision and high speed, who has more than 15 year’s experience in designing and manufacturing rc bearings for rc racing industries. Usually rc bearings are with shields or rubber seals,in order to improve the performance in racing, Runstar has designed and manufactured hybrid ceramic rc bearings,It is rc bearings with silicon  nitride balls to improve the speed, decrease the weight,heat and friction in racing. The rc model bearings from Runstar Bearing has the following characteristics.
1full size of rc bearings available. Runstar design and manufacture full sizes of rc bearings with a bore size from 1mm to 20mm for rc modelsit consists of metric miniature ball bearing, inch miniature ball bearing and miniature flange bearings.

2High Precision to meet all needs in quality. Runstar’s RC Bearings have different grade from ABEC-1 to ABEC-7 for choice.

3High speed . It is one of the most basic requirements of rc bearings. RC Bearings with high speed can give full play to the performance of rc models.

4Long life. The long-time rotation with high speed is a great test for the service life of the rc bearings. Runstar’s rc bearings are strictly controlled and managed from the selection of materials and each process to ensure that each rc bearing can be durable.

5customized rc bearings is accepted.
