Original japan Long Life Low Friction bearing , ZZ 2RS 638 single ball bearing
Our precision deep groove ball bearings are designed for high
precision, low noise, small vibration, high reliability and long
life. They are mainly used in various types of electric motors.
They are also known as EMQ (Electric Motor Quality) bearings.
EMQ bearings are widely used in household appliances, toys,
electric power tools, car motors and other fields. With optimal
design, high reliability heat treatment, precision manufacturing
processes and high-grade grease, these products perform better on
reliability, vibration and noise levels than standard products
making them more suitable for electric motor applications. These
products can also be applied to most gearbox applications as well.
