Direct Supply from Precision Steel Ball Manufacturer - 100Cr6 Bearing Steel Balls, 7.938mm & 8.0mm, G16 Bearing Balls

 Bearing steel ballThe key lies in the differentiation of levels, that is,Ball bearings made of bearing steel offer many precision levels.According to the National Standard GB/T308-2002 grade list, it is divided into G5, G10, G16, G28, G40, G60, G100, G200, G500, G1000, etc. "G" stands for the letter before "Grade" in English, and the numbers represent different grades.The smaller the number, the higher the precision, the better the steel ball.High precision is generally used in precision machinery, automotive parts, aerospace, and other industries with high requirements, while low precision is usually used in industries such as grinding, crushing, and stirring.

Ball bearings, as the main component of bearings, directly affect the working performance and service life of the bearings. With the advancement of technology, there is a growing demand for higher noise levels, precision, reliability, and service life of bearings.Bearings steel ballQuality requirements have also been elevated. The key to the quality of steel balls lies in not only raw materials but also the processing equipment, with the grinding process being the most critical aspect. As steel ball production equipment continues to be updated and replaced, resin grinding wheels with more advantages are now widely used in precision grinding equipment.

Let's take a look below:

Resin bonded grinding wheels are made by mixing high-precision abrasive micro-powders with high-strength adhesives, and then compacting, hardening, and processing them. The abrasive particles required have a uniform diameter, with no large particles to cause scratching.Steel ballSurface. The adhesive is composed of various imported resins in proportion, offering good adhesion, heat dissipation, and elasticity. The characteristics of the resin abrasive wheel are: fine particle size, high hardness, uniform and dense internal structure, adaptable to various grinding conditions and suitable for different specifications of steel balls, with a regular appearance as well.Steel ball processingDuring the process, initial and fine grinding operations typically use cast iron plates combined with abrasives for polishing. To enhance the quality of steel balls, we now employ fine-grained resin grinding wheels in place of the original cast iron plate method with coolant and abrasives. The initial grinding uses fine-grained grinding wheels, while the fine grinding operation utilizes ultra-fine-grained resin grinding wheels, significantly improving the surface morphology and quality of the steel balls.

Your concerns and questions, we address one by one here:

How to choose steel balls?

(1). If you're looking for high hardness and wear resistance, opt for bearing steel ball for its wear resistance, followed by carburized carbon steel ball.

(2). If you need to weld something with low hardness, you should use carbon steel balls without heating, commonly known as iron balls.

(3). For superior rust prevention, opt for stainless steel balls, available in grades 304, 316, and 316L, with increasing rust resistance.

(4). For excellent rust prevention and high hardness, choose 440 grade stainless steel balls.

(5). For high precision, choose a higher grade; the smaller the number, the higher the grade, and the better the precision.

 If the above doesn't address your questions or you're still unsure about the type of steel ball you need, feel free to ask our customer service team. Clearly explain your application, and our professionals will provide you with a professional answer to ensure your satisfaction!

2. Quality Assurance

Raw Material Assurance: Sourcing steel billets from major steel mills.

(2). Production Equipment Assurance: Introduction of production equipment and testing instruments.

(3). Technical Support: Over a decade of technical staff provide 24/7 on-call production oversight and control.

(4). Rigorous and scientific production management system: Strict administration, adherence to production regulations, and traceable accountability in reverse.

(5). A sealed and tidy cleanroom: Ensures the high precision production of precision steel balls.

3. Shipment Information

（1). Samples shipped via SF Express: A limited number of samples are available free of charge, with shipping charges to be paid by the recipient.

(2) Shipments under 300 kg use Yousu Express, Best Express, Debang Logistics, or courier services, as well as Jiayi Logistics, Shangqiao Logistics, etc.

(3). Shipments over 300 kg use dedicated logistics; generally, pick up from the city logistics center. If pick-up from the county/district is required, please specify; additional delivery fees apply.

4. Packaging

We offer a variety of packaging options, including woven bags, cardboard boxes, pallets, steel drums, bottled, and ton bags, and can custom make packaging to meet customer requirements.

5. Where is the shipment dispatched from?

Due to our factory's location in the countryside, logistics and express delivery are not convenient. Therefore, we lease a large warehouse in a large logistics park in Liaocheng city to store goods and ship them to our customers.

6. Return and Exchange Policy

If the issue is our responsibility due to quality non-conformity, we cover the round-trip shipping costs for returns and exchanges. If the responsibility lies with the buyer, returns and exchanges are possible as long as it doesn't affect resale, with the buyer covering the shipping costs both ways.
