6206CE Deep Groove Full Ceramic Bearings / Precision High Speed Ceramic Bearings
Full Ceramic Bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPM’s, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present.
Full Ceramic Bearings are usually made of following materials:
Full Ceramic bearings are used in specialty applications like chemical baths, vacuum environments, semiconductor manufacturing, food processing industries, radiotherapy, MRI, patient positioning systems and more. Any extreme environment that requires non-corrosive, non-conductive or non-magnetic bearings is ideal for full ceramic bearings.
Because ceramic is a glass like surface it has an extremely low coefficient of friction and is ideal for applications seeking to reduce friction. Ceramic balls require less lubrication and have a greater hardness than steel balls which will contribute to increased bearing life. Thermal properties are better than steel balls resulting in less heat generation at high speeds.
Radial Full Ceramic Bearings
Full Ceramic Bearings are made entirely of ceramic material and are superior to common steel bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPM's, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present.
Applications such as cryopumps, medical devices, semiconductors, machine tools, turbine flow meters, food processing equipment, robotics and optics. Ceramic materials commonly used for bearings are Silicon Nitride (Si3N4), Zirconia Oxide (ZrO2), Alumina Oxide (Al2O3) or Silicon Carbide (SiC.)
Because ceramic is a glass like surface it has an extremely low coefficient of friction and is ideal for applications seeking to reduce friction. Ceramic balls require less lubricant and have a greater hardness than steel balls which will contribute to increased bearing life. Thermal properties are better than steel balls resulting in less heat generation at high speeds. Full Ceramic bearings can have a retainer or full complement of balls, retainer materials used are PEEk and PTFE.
Full ceramic bearings can continue to operate under extremely high temperatures and are capable of operating up to 1800 Deg. F. Ceramic is much lighter than steel and many bearings are 1/3 the weight of a comparable steel bearing. Full ceramic bearings are highly corrosion resistant and will stand up to most common acids, they will not corrode in exposure to water or salt water. And finally full ceramic bearings are non-conductive.
The purpose of a radial bearing is to reduce rotational friction and support loads. This is achieved by using two races to hold the balls and to spread the load through the balls. As the bearing race rotates it causes the balls to rotate. The ball provides for substantially less rolling resistance and coefficient of friction than if two flat surfaces were rotating.
Single-row, deep groove radial ball bearings are the most common bearing type, having a wide range of applications. Radial bearings are made with very high levels of precision and used in applications where rotational performance and low torque is necessary, but load is a secondary issue. Deep-groove bearings however do have higher load ratings for their size than shallow-groove ball bearings, but are also less tolerant of misalignment.
Ceramic hybrid ball bearings use ceramic balls. Ceramic balls weigh up to 40% less than steel balls, depending on size. This reduces centrifugal loading and skidding, so hybrid ceramic bearings can operate up to 50% faster than conventional bearings. This means that the outer race groove exerts less force inward against the ball as the bearing spins. This reduction in force reduces the friction and rolling resistance. The lighter ball allows the bearing to spin faster, and uses less energy to maintain its speed. Ceramic hybrid ball bearings use these ceramic balls in place of steel balls. They are constructed with steel inner and outer rings, but ceramic balls so they are known as hybrids.
