The Brief Introduction of 698 (8mmx19mmx6mm) Ceramic Ball Bearings

The "698" designation typically refers to a specific bearing size within the metric bearing system. In this case, "698" refers to a bearing with an inner diameter of 8 mm, an outer diameter of 19 mm, and a width of 6 mm. As for the ceramic material used in a 698 ceramic bearing, it can vary depending on the manufacturer and specific application. Silicon nitride (Si3N4) and zirconia (ZrO2) are commonly used in bearings, including the 698 type. These ceramics offer advantages such as high hardness, low friction, and resistance to corrosion and wear.

The 698 Ceramic Ball Bearings Applies to Construction Machine

---If You're Using 698 Ceramic Bearings in the Construction Machine, You Will Getting:

♦Heavy Load Capacity: Construction machines often operate under high loads and intense vibrations. Ceramic bearings have excellent strength and hardness, enabling them to withstand heavy loads without deformation or premature wear. This ensures reliable operation and extends the lifespan of the bearings.

♦Resistance to Wear and Corrosion: Ceramic materials, such as silicon nitride or zirconium dioxide, have superior resistance to wear, corrosion, and chemical attack compared to steel. In construction environments with abrasive particles, moisture, or corrosive substances, ceramic bearings can maintain their performance and integrity for longer periods. This reduces maintenance requirements and minimizes the risk of bearing failure.

♦Temperature Resistance: Construction machines often generate significant heat during operation, especially in heavy-duty applications. Ceramic bearings have excellent thermal properties and can withstand higher temperatures without compromising their performance. This makes them suitable for construction machines that operate in hot environments or undergo rapid temperature fluctuations.

♦Energy Efficiency: The lower friction of ceramic bearings reduces energy consumption in construction machines. With reduced frictional losses, the machines require less power to operate, resulting in improved energy efficiency and potentially lower operating costs over time.

  Beijing Zhongxing Shiqiang Ceramic Bearing Co., Ltd., founded in 2005, situated in No. A38 Weishanzhuang Industry District, Daxing District ,Beijing, is the first company in China to invent and manufacture rare-earth ceramic bearings. The rare-earth ceramic bearings have characteristics of strong resistance against all kinds of acid, alkali, salt and other corrosive medium erosion, high temperature resistance, wear-resistant, dimensional stability at high temperature, etc. They can be used in worse lubrication working condition with a long operating life, thus it is a new kind of high-tech products material, with great social and economic value.

  Besides, the founder of the company started theoretical research and process development on ceramic bearings as early as 1982, and obtained two national invention patents in 1992/1994 (Patent No. ZL92114993X for rare-earth ceramic bearings and Patent No. ZL94106294.S for ceramic ball processing technology).

  At present, our company mainly produces ceramic bearings, sliding bearings, ceramic balls and ceramic industrial parts. The production materials are high performance ceramic materials, mainly SSIC, Si3N4, ZrO2, Al2O3.

  The advantage of our company is that we have specialized production line for high precision ceramic balls, and we can produce customized GPS (Gas Pressure Sintering) and HIP (Hot Temperature Isostatic Pressing) sintered Si3N4 balls and ZrO2 balls. The quality of our products is equivalent to ASTM F2094 F2094M-08 standard class I and II materials, and the precision grade reaches international standard G3, G5, G10 ceramic bearing balls, etc. Please note that the most of equipment used in our production and testing process are from Mitsutoyo Japan, and the hot isostatic sintering furnace is from ABB Sweden, therefore, the quality of our products is absolutely superior. And we are confident that you will be satisfied with our products.
