Micro bearing is a kind of deep groove ball bearing. Usually, we refer to single row micro deep groove ball bearing with inner diameter less than 10mm. Kunjing bearings can provide micro ball bearings of various materials, including bearing steel, stainless steel and ceramics. In addition to conventional micro bearings, we can also manufacture micro flange bearings and micro thrust bearings. We can also customize micro non-standard bearings according to customer requirements.
Kunjing bearing has the double advantages of price and quality among domestic miniature bearings.
As a professional micro bearing manufacturer, kunjing bearing has established the development direction with technological innovation as the core competitiveness since its establishment.
Micro small bearings have the following characteristics:
1. Sealing form: open type (without cover), metal shielding belt dust cover (zz), rubber sealing ring (2RS).
2. Accuracy grade: ABEC – 1, ABEC - 3, ABEC - 5, ABEC - 7, ABEC - 9. According to the value from small to large, the accuracy grade is getting higher and higher.
3. Speed: we can provide high-speed micro bearings with a maximum speed of 450000 revolutions. These high-speed bearings are mainly used in the fields of spindle, dental drill and mobile phone. We also provide low-speed bearings for jewelry, toys, industrial robots and other industries.
4. Retainer: retainer is an important part of bearing. Usually, stainless steel retainer is used for micro bearing, but many customers like nylon cage micro bearing.
5. Type: distinguished from the model, micro bearings include 68, 69, 60, 62 and Mr series bearings. Traditionally, we have become micro zero type bearings.
6. Applications: micro motors, fitness equipment, telecommunications equipment, instruments, computers, automobile motors, precision instruments, mechanical equipment, household appliances, medical instruments, fishing gear, remote control toys, high temperature resistance and other fields.
