The miniature bearing usually refers to single-row miniature deep groove ball bearing with its inner diameter within 10 mm. Yuhang bearing can provide various miniature ball bearings made of different materials, including bearing steel, stainless steel and ceramics. In addition to normal miniature bearings, we also manufacture miniature flanged bearings, miniature thrust bearings and customized non-standard miniature bearings based on customers' requirements.

Yuhang bearing,  specialized in producing miniature bearings since 2000, has strong advantages in price and quality among the domestic miniature bearing enterprises.

As a specialized manufacturer of miniature bearings, has set the development direction on the basis of technological innovation as the core competetiveness since its foundation 

The characteristics of miniature bearings are as follows:

1.Way of Sealing: open(without cap), metallic shield with dust cover (ZZ),  rubber seal

2.Accuracy Grade: ABEC - 1 , ABEC- 3 , ABEC- 5 , ABEC- 7 , ABEC- 9 , the bigger the value is, the higher the accuracy grade is.

3.Rotation Speed: we can provide high speed miniature bearings with the maximum rotation speed at 450,000rm, which are mainly used for spindles, tendal drill handpieces. We also offer low speed 4.Bearings for  jewelry, toys, industrial robots ets.

5.Cage: an important part of bearing, which is usually made of stainless steel. But some customers prefer bearings with nylon cages.

6.Type:  miniature bearings can be devided into 68 series,69 series,60 series,62 series,MRseries according to the types, which are traditionally called Type 0 miniature bearings

7.Application: They are used for miniature motors, fitness equipment, telecommunications equipment, instrumentation, computers, automobile motors, precision instruments, machinery and equipment, home appliances, medical equipment, fishing gears, remote control toys, high temperature resistance etc.
