Inquiry (采购产品): Elevated temperature ball bearings Do you have ball or roller bearing the could handle the following conditions: Bearing temperature: ~750 F Bore (range): .3125 - .375 Dynamic and Static Load: 400 lbf Rotational Speed: 500 to 1000 rpm Typical run time: 2 minutes Minimum Life of Bearing: 5 runs at 2 minutes each Target Life of Bearing: 20 runs at 2 minutes each. The housing and shaft would both be at about the same temperature (within 50 F), though there may be a few seconds during startup where there could be a delta T of 200 degrees. The bearing would be room temperature at startup. **** Hidden Message ***** Denny Graham Tucson, AZ 85712 USA Company: Graham & Associates E-mail: denny_graham@msn.com **** Hidden Message ***** denny_graham@msn.com
