The thin-walled bearings provided by kunjing bearings include open type, metal closed type and rubber sealed type. The dimensions of these bearings include British series and metric series. In addition to standard dimensions, they can also be customized according to customer requirements. The materials of these thin-walled bearings are divided into bearing steel and stainless steel. Stainless steel thin-walled bearings have very good rust and corrosion resistance.

The Thin-walled bearing of kunjing bearing is widely used in robots, medical instruments, office instruments, testing instruments, deceleration and speed change devices, optical and imaging instruments, stepping motors and so on. The biggest feature of thin-wall bearing is that the wall bearing makes the miniaturization and lightweight of product design easy!

Kunjing bearing has more than 300 kinds of thin-walled bearings. The following are the specific product models:

Series inch thin wall bearing - Inch series size, inner diameter size range 9.525mm – 41.275mm

6700 series - metric size, ultra-thin wall bearing, can only withstand very light loads

6800 series - metric size, Thin-walled bearing, capable of withstanding light loads

63800 series – metric size, is a widened version of 6800 series

6900 series - metric size, able to withstand heavy loads

Kunjing bearings also have mixed ceramic ball bearing material models

Hybrid ceramic ball bearing, especially silicon nitride ball hybrid ceramic bearing, has the characteristics of low density, high hardness, low friction coefficient, anti magnetoelectric insulation, wear resistance, self-lubricating and good rigidity. It has good acid and alkali resistance, self-lubricating function, high temperature resistance above 300 ° C, high wear resistance, greatly reduces rolling, friction force and calorific value at high speed, and has a long service life, which is 3 ~ 5 times that of all steel bearing The weight of ceramic material is 60% lighter than that of steel, and the elastic modulus of the same rigid ceramic material is 50% higher than that of bearing steel.

Hybrid ceramic ball bearings are especially suitable for rolling elements of high-speed, high-precision and long-life steel ceramic hybrid bearings (inner and outer rings are metal). Generally, the inner and outer rings are made of bearing steel or stainless steel, and the ceramic balls can be made of ZrO2, Si3N4 or SiC materials.

Among them, Si3N4 has superior comprehensive performance and has become the preferred material for steel ceramic hybrid ceramic bearings.

Kunjing company, a professional manufacturer of flange outer ring flange bearings, produces all kinds of micro flanged bearings, including metric, British and stainless steel. There are more than 180 models, and the inner diameter of flanged bearings ranges from 1 to 12mm. Flange bearing is characterized by flange flange on the outer ring, which can simplify the structure of the host, reduce the size of the host and make the bearing easier to locate.

Product size:

-Metric micro flange bearing

-Inch micro flange bearing

-Inner ring extension flange shaft

Product characteristics of micro flange bearing

1. Series products with flanges on the outer wheel make axial positioning simple; The bearing pedestal is no longer needed and becomes more economical.

2. In order to obtain low friction torque, high rigidity and good rotation accuracy of the bearing, a steel ball with small outer diameter is used.

3. The use of hollow shaft ensures lightweight and wiring space.

4. According to the requirements of customers, we can provide micro flange bearings of various materials, including bearing steel, stainless steel, ceramics
