6200 series Deep Groove Ball Bearing Manufacturers

1. What are the core technical parameters of the 6200 series deep groove ball bearings?
As a classic representative of deep groove ball bearings, the 6200 series is known for its high precision, low friction and versatility. Taking the standard model 6200 as an example, the inner diameter is 10mm, the outer diameter is 30mm, and the width is 9mm. It can withstand radial loads and bidirectional axial loads, with a basic rated dynamic load of 5.4kN, a static load of 2.36kN, and a maximum speed of up to 36000r/min (open design). It has a simple structure, low maintenance requirements, and can adapt to dusty or humid environments through seals or dust cover designs (such as 2RS, 2Z and other variants).

2. Why is the 6200 series called the "heart" of industrial machinery?
This series of bearings is widely used in centrifuges, CNC machine tools, motors, reducers and other equipment. Its high speed capability and stability make it a core component of precision mechanical transmission. For example, in high-speed motors, the 6200 series can support continuous operation of tens of thousands of revolutions; in high-temperature scenarios such as metallurgy or boiler fans, variants of special materials (such as stainless steel or high-temperature resistant coatings) (such as 6200-2Z/C3WT) can withstand extreme environments of 300°C.

3. How does Ningbo Yuhong Bearing achieve high-quality production of the 6200 series?
Yuhong Bearing uses fully automatic production lines and equipment imported from Japan, with an annual production capacity of over 80 million sets, covering all models of the 6200 series (including 2RS and ZZ sealed types). Its own brand KJYJ uses a material combination of "chrome steel rings + stainless steel cages" to ensure wear resistance and corrosion resistance, while controlling accuracy through ABEC-1 tolerance grades and CN-level radial clearance. The company also supports customized production to meet the special needs of different industries.

4. How does Yuhong Bearing's cultural concept empower product competitiveness?
With "sharing growth benefits" as its core value, the company integrates the integrity and craftsmanship spirit in Chinese culture into production management. For example, through strict quality inspection processes (such as checking the smoothness of the inner wall carbon cloth) and on-time delivery commitments, the stable operation of customer equipment is guaranteed. This cultural cohesion has won it a reputation in the markets of more than 50 countries and regions, and has become a benchmark supplier of small and medium-sized deep groove ball bearings.

5. How to choose the appropriate 6200 series variant model?
According to the application scenario requirements:
Conventional environment: open 6200 (low cost, easy lubrication).
Dust and water proof: 6200-2RS (contact rubber seal) or 6200-2Z (non-contact metal dust cover).
High temperature/corrosive environment: 6200-2Z/C3WT (stainless steel material + high temperature resistant coating). Yuhong Bearing provides a full range of products from standard models to special coatings, and can match the best solution through technical consultation.

6. Future technical trends of the 6200 series and Yuhong's layout
As industrial equipment develops towards high speed and lightweight, the maximum speed and load capacity of the 6200 series will continue to be optimized. Yuhong has already started to develop ceramic ball bearings (such as zirconium oxide) to further improve high temperature resistance and friction reduction performance, while also improving customer experience through digital services (such as online generation of 3D drawings).
