6300 series Deep Groove Ball Bearing Manufacturers

6300 series deep groove ball bearings
The 6300 series deep groove ball bearings are single-row bearings, with deep raceway grooves both inside and outside. They are able to withstand radial loads as well as finite axial loads in both directions. "6300" in the name indicates the nominal dimension of the bearing, that is, the inner diameter.
Features of 6300 series deep groove ball bearings:
Generality: These bearings are widely used and are widely used in various occasions, including motors, automotive parts, industrial machinery, pumps, etc.
Radial load bearing capacity: Deep raceway grooves enable the bearing to withstand radial loads, that is, forces perpendicular to the axis of the shaft. Bearings can withstand light and moderate radial loads.
Axial load capacity: Although the 6300 series bearings are mainly designed for radial loads, they can withstand limited axial loads in both directions. However, they are not suitable for bearing heavy axial loads compared to thrust ball bearings.
Speed ​​and low friction: The raceway surface of the deep groove ball bearing is smooth, so the friction is relatively small. This enables them to run at high speed.
Sealing Options: The 6300 Series Bearings offer a variety of sealing options to prevent contaminants and maintain lubrication, depending on the specific variant. Common sealing options include rubber seal (RS) or metal shielding (ZZ).

6300 series Deep Groove Ball Bearing Industry knowledge

How do 6300 series deep groove ball bearings achieve the industry trust of Ningbo Yuhong Bearings?
1. Why have 6300 series deep groove ball bearings become the "universal star" in the field of machinery?
As a classic representative of deep groove ball bearings, the 6300 series has a compact design with an inner diameter of 10mm, an outer diameter of 35mm, and a width of 11mm. It is suitable for high speed and multi-load scenarios and is widely used in precision equipment such as motors, automobiles, and home appliances. How can its performance advantages of 8.52kN dynamic load, 3.4kN static load, and a maximum speed of 32000r/min help Ningbo Yuhong Bearings meet the diverse needs of global customers with precise parameters?

2. How does the 6300 series balance durability and low noise during high-speed operation?
This series uses chrome steel rings and stainless steel cages, combined with the CN-level radial clearance standard, which not only ensures the stability of the bearing at high temperatures (up to 120°C), but also reduces friction noise through precision machining. How does Ningbo Yuhong transform this technology into "quiet and reliable" in the eyes of customers through strict quality control of ABEC-1 tolerance level?

3. From domestic to international brands, how does the 6300 series break through technical barriers?
Domestic 6300 bearings achieve performance benchmarking with international brands such as SKF and NSK through P5/P6 level precision technology. And with 20 years of manufacturing experience, how does Ningbo Yuhong Bearing upgrade traditional deep groove ball bearings to "intelligent transmission units" adapted to new energy and automation equipment, leading the industry's technological iteration?

4. Why can Ningbo Yuhong's 6300 bearings become the "trust link" of customer supply chains?
Through non-standard customized services such as special clearance and lubricant adaptation, Yuhong Bearing not only meets the existing needs of customers, but also develops special models such as corrosion resistance and anti-magnetic in a more forward-looking manner.

5. From products to responsibilities, how does Yuhong Bearing build a "trinity" trust system?
In terms of environmental responsibility, Yuhong reduces the dependence of traditional bearings on petrochemicals through the research and development of bio-based materials; in terms of employee value, technical training and equity incentives are used to gather team innovation; in terms of social feedback, it participates in the manufacturing single champion plan and integrates corporate growth into the national high-end equipment strategy - how can this multi-dimensional responsibility practice reshape the "Made in China" image of the bearing industry?

Through the discussion of the above issues, the 6300 series deep groove ball bearings are not only the technical carrier of Ningbo Yuhong Bearings, but also the epitome of its development with customer needs as the anchor and social responsibility as the driving force. From micro parameters to macro missions, Yuhong is driving the global trust of China's smart manufacturing with the "core of bearings".
