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.
1:full size of rc bearings
available. Runstar design and manufacture full sizes of rc bearings with a bore
size from 1mm to 20mm for rc models,it consists of metric
miniature ball bearing, inch miniature ball bearing and miniature flange
bearings.
2:High Precision to meet all
needs in quality. Runstar’s RC Bearings have different grade from ABEC-1 to
ABEC-7 for choice.
3:High 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.
4:Long 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.
5:customized rc bearings is
accepted.
