Load Ratings Temperature
Aircraft Static Capacity ( ASC )is the maximum load which can be placedon a housing mounted needle roller bearingwithout seriously brinelling the raceways(approx. 0.0001 inch deep) or deforming the rolling elements. Unsealed aircraft bearings can be operated at temperatures up to 400 ĖF provided that suitable lubrication is present. Highertemperature exposure will result in loss ofcapacity. The operating temperature for sealed bearings is limited to 250 ĖF due to the seal material. Limit Load Rating is the maximum static load that can be appliedwithout impairing the subsequent function ofthe bearing.Stainless Steel
Ultimate Static Fracture Load Rating Smith Bearing® produces Stainless Steelairframe bearings which are dimensionally interchangeable to our standard line ofbearings listed in this section. The specialgrade of stainless steel used has extremely high strength and corrosion resistance.Material used is per AMS 5925 or AMS 5898 for inner races, outer races, studs and rolls and AMS 5621 for end washers. Consult our engineering department for exactspecifications and applications. is a minimum of 1.5 times the Limit Load Rating Track Roller BearingsYAF , YAT , YAD , and YAS Series bearings aredesigned for use as a Track Roller and thereforeoperate with an unsupported outer race. For this reason deformation of the outer race mustbe taken into consideration. The dynamicrating method used for track roller bearings is the Rating as a Track Roller which equals 1/3 ASC (Aircraft Static Capacity). The Limit Load Rating for track roller bearings equals 4/9 ASC (Aircraft Static Capacity). HRS and CHRS Series bearings with integralstud are designed for use as a track roller. For these bearings the Limit Load Rating equals 2/3 ASC (Aircraft Static Capacity).
