temperature rise of double-row tapered roller bearings
US4085984A
A high speed bearing assembly for supporting a shaft within a housing includes two single row tapered roller bearings mounted indirectly so as to in effect create a double row bearing which is capable of accommodating thrust loading in both axial directions as well as radial loading The cones of the two bearings are clamped tightly together on a shaft with their thrust ribs and back faces

3 Steps on How to Install Tapered Roller Bearings Properly
People generally use tapered roller bearings in pairs And three aspects are very important during installation: choosing installation coordination adjust the axial clearance test the bearing running and detect the temperature The selective fit of tapered roller bearings 📷 The outer ring of the original roller bearing and the housing
Tapered Roller Bearings Selection Guide
Tandem bearings have roller rows which are placed next to each other with the same load-bearing orientation This is only for instances where a single row does not meet the load requirements and a larger bearing diameter is unacceptable Double-cup tapered roller bearings locate the rollers so that their apexes face each other The outer raceway features two grooves in a single-piece
