Ceramic bearings exhibit a vast range of advantages for engineering applications but also have disadvantages that must be taken into consideration. They are extremely hard, corrosion-resistant and have a high elastic modulus.
When it comes to load and speed ratings, 440 stainless steel bearings are the clear winners. Full ceramic zirconia bearings can support roughly 90% of the 440 stainless bearing load and 20% of the speed.
13 Μαΐ 2024 · Both bearing steel and ceramic bearings have their own advantages and suitable scenarios, and selecting the appropriate bearing material depends on specific application requirements and considerations.
In terms of load and speed ratings, 440 stainless steel bearings are the clear winner. Fully ceramic zirconia bearings can support approximately 90% of the load and 20% of the speed of a 440 stainless steel bearing. Next the silicon nitride bearing has 75% load/25% speed.
Check out our ceramic bearings guide, if you are sourcing a bearing for this environment. For high speed use, low to medium temperature (less than 120°C constant and/or 150°C intermittent) use corrosion resistant 440 stainless steel bearings. Consider polyamide cage and/or ceramic balls for higher speeds.
Ceramic bearings are made from silicon nitride, zirconia, or a combination of both. These materials are known for their high strength, hardness, and resistance to corrosion. On the other hand, stainless steel bearings are typically made from AISI 440C stainless steel, which offers good corrosion resistance and durability.
The difference between ceramic and steel bearings is, of course, the material. Made from silicon nitride, ceramic bearings are heralded for their reduced rolling resistance, increased hardness...
