Dodge® 023071 315 Type E-Xtra Pillow Block Roller Bearing, 4 in Dia Bore, 12-1/4 to 12-3/4 in L Bolt Center-to-Center, 4-1/4 in Base to Bore Centerline, 15-1/4 in OAL x 8-1/2 in OAH

Type e-xtra, type K, double interlock, TAF and EXL mounted bearings are all general purpose high capacity tapered roller bearings capable of handling any combination of radial and thrust load within the capacity of the bearing. All of these bearings are mounted to the shaft by means of set screw collars having 65 deg set screw spacing for optimum clamping force. The type e-xtra, double interlock, TAF and EXL mounted bearings have locking collars at each end of their extended inner races. Type K has a single locking collar. The tapered roller bearings for these mounted bearings all have case carburized inner races (cones), outer races (cups) and rollers. Bearings are preassembled, prelubricated and factory adjusted. They are normally equipped with land riding contact type seals with a metal deflector guard. The standard housing material for most of these mounted bearings is ASTM A48 class 30 iron having a minimum tensile strength of 30000 psi. The outer housing for the type K and double interlock flange bearings thru 4 in bore size and all type EXL housings utilize housings made of ductile iron (ASTM A536 grade 65-45-12) with 65000 psi tensile strength. Type E pillow blocks are also available with cast steel housing having a tensile strength of 70000 psi for 2-bolt base thru 3-1/2 in bore size and 4-bolt base from 3-15/16 thru 5 in bore size on an assembled or order basis. The type K, double interlock pillow blocks and flange bearings plus the TAF pillow blocks all have split outer housings used with completely assembled, lubricated and adjusted inner units simplifying replacement of the bearing in the pillow block or flange bearing. All type E mounted bearings, type K take up units and all D units, S-1 units and B-1 units have solid one piece housings.
