Specification of 17X40X12mm Zro2 Zirconia Ceramic Deep Groove Ball Bearing 6203ce

This 17x40x12mm Zro2 Zirconia Ceramic Deep Groove Ball Bearing uses the common 6203 size. Its dimensions are clear: 17mm inside, 40mm outside, 12mm wide. This specific model is the 6203CE type. The “CE” marking means both the rolling balls and the rings are made entirely from zirconia ceramic (ZrO2). It is a deep groove ball bearing design. This design handles both radial loads and some axial loads effectively.

Zirconia ceramic provides major advantages. It is extremely hard. This hardness makes the bearing very resistant to wear. It lasts much longer than standard steel bearings in tough conditions. The material is also chemically inert. It resists corrosion from acids, alkalis, and salt water perfectly. This is critical for harsh chemical environments or marine use. Ceramic is non-magnetic. This bearing causes zero magnetic interference. It works well in MRI machines or sensitive electronic equipment. The material is an electrical insulator too. It prevents electrical arcing damage common in motors or generators.

This all-ceramic construction allows the bearing to run at higher speeds. It generates less friction and heat than steel. The bearing can handle much higher temperatures. It operates reliably up to 800°C (1472°F) in air. It needs minimal lubrication. It can even run dry in some situations. This reduces maintenance needs. The bearing is much lighter than a steel equivalent. This lowers the overall weight of the machinery.

The 6203CE ZrO2 bearing fits applications demanding high performance. It excels where corrosion, high heat, electrical insulation, or high speeds are problems. Common uses include chemical processing pumps, food and beverage machinery, high-speed spindles, medical devices, and vacuum equipment. Its deep groove design ensures reliable operation under combined loads. This bearing offers a long service life under demanding conditions.

Applications of 17X40X12mm Zro2 Zirconia Ceramic Deep Groove Ball Bearing 6203ce

This 17x40x12mm Zro2 Zirconia Ceramic Deep Groove Ball Bearing, model 6203ce, is built for tough conditions. It uses zirconia ceramic balls and rings. This material change makes a big difference. Zirconia ceramic is very hard. It resists wear much better than steel. This means the bearing lasts longer under heavy loads or high speeds.

The ceramic material doesn’t rust. Water or chemicals don’t damage it. This is vital for wet environments. Think chemical pumps or marine equipment. Salt water won’t cause problems. Food processing lines need clean parts. This bearing fits perfectly. It won’t corrode or contaminate products.

High heat is another challenge. Zirconia ceramic handles much higher temperatures than standard steel bearings. Motors or machinery running hot won’t ruin this bearing. It keeps working reliably. Electrical insulation is another key benefit. Ceramic doesn’t conduct electricity. This prevents electrical currents from damaging the bearing. Motors or generators using variable frequency drives need this protection. Electric arcing won’t occur.

Low lubrication situations are manageable. Ceramic has a lower friction coefficient than steel. It runs smoother with less grease. This is useful where relubrication is hard. Medical devices or semiconductor tools often use these bearings. They offer precision and avoid metal particle contamination. The bearing performs well in vacuums too. It doesn’t outgas like some materials. Cleanroom applications benefit from this.

This 6203ce size is common. It fits many standard machines needing an upgrade. Replacing a steel bearing with this zirconia ceramic one boosts performance. You get longer life in corrosive, high-temperature, or electrically active settings. It provides reliable rotation where ordinary bearings fail quickly.

5 FAQs of 17X40X12mm Zro2 Zirconia Ceramic Deep Groove Ball Bearing 6203ce

People often ask about our 17x40x12mm Zirconia Ceramic (ZrO₂) Deep Groove Ball Bearing, model 6203CE. Here are the top questions:

What makes ceramic bearings better? Zirconia ceramic is very hard. It resists wear much better than steel. This bearing lasts longer. It handles tough conditions well. Ceramic is also lighter than steel. It reduces friction. This means less energy loss. Ceramic doesn’t rust. Water or chemicals won’t damage it. It works fine in wet places. Ceramic doesn’t conduct electricity. It prevents electrical arcing. This is good for electric motors.

What size is this bearing? The bearing measures exactly 17mm inside (the hole). The outside is 40mm. The width is 12mm. This is the standard 6203 size. It fits where standard 6203 steel bearings go. You can swap it easily. Check your machine’s specs first. Make sure the sizes match.

How hot can this bearing get? The zirconia ceramic handles heat well. It works fine up to 300 degrees Celsius (572°F). This is hotter than most steel bearings manage. Don’t use it above this temperature. Extreme heat can damage the ceramic material. The cage material matters too. Check the cage specs for its max temperature.

Does it need special grease? Yes, you need the right grease. Standard greases for steel bearings might not work well. Ceramic surfaces interact differently with grease. Use a grease made for ceramic bearings. This ensures smooth operation. It prevents premature wear. It also helps the bearing reach its full lifespan. Ask us about compatible greases.

Can I use this bearing with steel parts? Yes, absolutely. The zirconia ceramic balls and rings work with steel shafts and housings. The bearing is designed for this. The dimensions match standard steel 6203 bearings. Just ensure the shaft and housing are the correct size. Installation is the same as a steel bearing. Use proper tools. Avoid hammering directly on the ceramic rings.
