About this file
This Statement of Work specifies requirements for 2 Double Nut Tapered Adapter Four-Bolt Pillow Block Bearings to be delivered to Anniston Army Depot. The bearings must be new, unused, and comply with ISO 492 and American Bearing Manufactures Association 20 standards, meeting P0/P6 bearing class tolerances.
The technical specifications detail a heavy-duty mounted bearing with 7-inch shaft size, steel housing construction, and relubricatable capability. Key load ratings include 525,000 lbf static load and 365,000 lbf dynamic load. Precise dimensional requirements are provided across 10 different measurements, including overall dimensions of 34.38 inches length, 19.75 inches height, and 27.5-30.5 inches width. The parts must be delivered to Building 5 at Anniston Army Depot on a box, pallet, or skid mount. Two detailed engineering drawings are included showing multiple views and dimensional details of the bearing assembly.
