100 pcs 5.5mm G10 precision zirconia ZrO2 and similar items

Description Item: 5.5 mm G10 precision zirconia ZrO2 ball beads Dimension:5.5mm Material: Zirconia Zirconia ceramic balls (ZRO2) Zirconia ceramic ball, at room temperature with high strength and high toughness, wear resistance, high temperature resistance, corrosion resistance, high stiffness, non-magnetic, electrical insulation. Zirconia ceramic balls at 600 ?, strength, hardness is almost constant having a density of 6.00g / cm3, a thermal expansion coefficient close to the metal if the expansion coefficient, may be used with metal bonding. Silicon nitride ceramic balls (SI3N4) Silicon nitride ceramic balls are precision ceramic non-oxidizing atmosphere at high temperature sintering, high strength, high wear resistance, high temperature, corrosion, acid and alkali, long-term use in the sea, and has absolute power absolutely magnetic good performance. At 800 ?, strength, hardness is almost constant, having a density of 3.20g / cm3, almost 1/3 of the weight bearing steel, when rotating the centrifugal force is small. High-speed operation can be realized. Also has a self-lubricating, it can be used without lubrication medium to high pollution of the environment. Become ceramic bearings, hybrid ceramic ball bearing material of choice. Silicon carbide ceramic balls (SIC) Ceramic Ball product performance and stability, with the best overall performance of silicon nitride. Compared with steel, lighter than steel quality, low friction coefficient, good sports performance, the elastic modulus of steel is 50%, the thermal expansion coefficient of less than 25% of the steel, the high temperature at 1000 ? before to maintain high strength and hardness, corrosion resistance, no rust, non-magnetic, can work without oil lubrication. I am in the production of advanced ceramic ball field level. Silicon carbide ball Material: sintered silicon carbide density: 3.15 g / cm3 Color: Black Level: G10, G16 Ceramic balls advantages: 1, high hardness. Ordinary Gcr15 bearing steel Vickers hardness 800HV, and zirconia ceramic ball hardness 1700HV above. 2, high wear resistance. In my company's product processing technology, for example, ordinary grinding balls (one millimeter margin) takes about 2-4 hours, and silicon nitride balls processing needs at least 150-200 hours. 3, corrosion-resistant. The stability of the ceramic material is the best, especially silicon nitride balls, hardly react with any substance, widely used in petroleum, chemical, food and other needs contact with strong oxidizing agents and strong reducing agents in the industry. 4, high temperature. Ceramic balls in the sintering process to go through thousands of degrees of heat and a lot of pressure, the internal molecular structure is very stable, very dense arrangement, which makes it a very low coefficient of thermal expansion, temperature changes almost no effect on the structure size. The operating temperature ceramic ball can reach 1,200 degrees Celsius or higher, its low impact is small, so it is widely used in the aerospace field. 5, light weight. Ceramic ball weighs only 50% -60% of the ordinary balls, in the field of aerospace bearings and promising. 6, self-lubricating. Ceramic ball itself has a good self-lubricating properties, high precision machining. You can reach the G5, G10 level, wear-resistant ceramic ball and structural stability, not easily deformed, so it can be finished, be applied to many specific industries. 7, insulating. Ceramic with good insulation effect. Package: 100 pcs 5.5mm G10 precision zirconia ZrO2 ball beads Payment 1. Customers can pay through various channels. 2. Make sure that the order is accurate before payment.Serouis purchase only International freight: 1. All orders are shipped from China. 2. All orders are transported by appropriate and reasonable freight mode, and the freight time is generally about 5-14 days. Typically international commercial delivery -- speedPak logistics. 3. Because there are regional differences in international freight transportation, some countries or regions are listed in our non-shipment list. But we can actually send it anywhere in the world. Buyers on the list only need to contact us to get postage and freight information in your area. Processing time 1. Usually, we will deliver the goods within 1-7 working days after receiving the order. Because ballscrew processing takes time, we will not set inventory of ballscrew and guide rail in theory, because most guests will ask to change the size, so most of them are produced, assembled and packaged now, Reducing secondary damage caused by placement or repackaging of goods. 2.Setting a 10-day processing date is to avoid problem from. Per-sales consultation: Our company has a professional team to reply to your consultation. Welcome to consult, welcome to customize your own CNC. After-sales and feedback Our company attaches great importance to after-sales problems. If there are any questions, we also have a professional team to answer them for you. If you are satisfied with our products and services, your positive comments to us are the greatest encouragement and support for us. International cooperation 1. If you are a factory or manufacturer and need stable supply, you can contact us. We support bulk procurement and shipping to reduce international costs. 2. If you are a local CNC parts seller, we can also provide you with sources of goods. We support mixed batches, but your purchase volume needs to reach a quantity. Only in this way can we minimize the cost and maximize your profits.
