Deep Groove bearing with seal 20*27*4mm 6704ZZ Thin Wall Ball Bearings

Deep Groove Thin Wall Ball Bearings 6704ZZ 20*27*4mm Z1 - Z4 Noisy Level

Ⅰ. About Miniature ball bearing:

We provide bearings without exceptional noise to ensure the silent running of the semiconductor device. Specially designed bearing shields are used to prevent the grease leaking, which may cause unexpected stop of the device. Moreover, we understand the concern about environment and energy saving.

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.

Ⅱ. Feature : high precision bearings have less internal friction and can work with smaller starting torque, which means a lower power consumption.

Ⅲ. Application: household appliances, dental drill, toys, electric power tools, electric motors, machine tools, measuring instruments, office machinery, Robot joint, facial beauty rollers, drone etc.

Ⅳ. Specification

• A deep groove ball bearings is the must popular type of rolling-element bearing composed of an outer race ball, an inner race and a bearing cage.and the race dimensions are close to balls dimensions.
• The materials for producing ball bearing are variety including stainless steel,chrome steel and silicon nitride and more with a simpler construction comparing with other ball bearing, deep groove bearings are suitable for large quantity production
• The function of deep groove ball bearings is to reduce rotation friction.those balls between outer race and inner race help avoid two flat surfaces rotating on each other thus to achieve the purpose of lowering down friction coefficient
• Additionally, deep groove ball bearings are primarily used to support radial loads; supports both radial and axial loads is also possible
• Deep groove ball bearings can be used in wide range of applications.

1. Firstly, they can de used in industrial transmission mechanical products.
2. Miniature 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.
3. Thirdly, our bearing are ideal for electrical motor with good quality and excellent performance. Because of their high precision, high rotating speed, high reliability, low friction and low noise, they are widely used in areas of machine tools, measuring instruments, office machinery, household appliances, various types of electric motors, industrial automation control, etc.
