Ordinary roller bearings can withstand how much heat? Thank youNow work conditions need to withstand 200 degrees or so, if you need high temperature grease, then what brand?
Ordinary bearings generally recommend the highest operating temperature of 120 degrees, and then higher, long-term work, metallographic structure will change.High temperature bearings can work at a temperature of 200 degrees for a long time because of their special heat treatment.If you want to work long term grease at 200 degrees, you need to use a total synthetic base grease, such as: SKF LGET2, but the price is quite expensive, about 1000 yuan per kilogram. If not, it is not recommended. You can use oil, gas, lubrication, etc. to dissipate heat, or add water cooling equipment to the bearing seat.
How many bearings can withstand temperature not only to see the process of bearing, also depends on the material used and the grease, use butter or MoS2 grease when the bearing temperature not exceeding 90 degrees, otherwise the lubricating oil will be melted and vaporized, bearing damage.Like bearings in a microwave oven, it can withstand 200 degrees of heat because it does not require grease.
General 200 or so, plastic cover of 120. specific, you see the certificate on all the grease is not clear, you go to the Internet search, there is high temperature grease to sell, you ask them, I saw the next 200 degrees can reach
In the ordinary high temperature grease will coking and make the jamming of the bearing, if the bearing long-term work under the high temperature of 200 degrees and not using oil bath lubrication, then you must use the whole fluorine grease, because it can only use for a long time under the high temperature of 200 degrees.
