The Barden L150HDF1500 is an inch‑style, two‑row ball screw support bearing (L‑series) with a 1.5 in bore and a 2.8346 in outside diameter, designed to support precision ball screws in machine tools. It features an open closure, a width of 0.625 in, steel bearing components, a phenolic cage, and is uncoated for robust performance. Rated for 4000 lb dynamic and 7500 lb static loads, it supports maximum speeds of 1100 rpm when grease‑lubricated and 1600 rpm when oil‑lubricated, with a standard preload around 1500 lbs. Common applications include supporting ball screws in CNC machines and other precision equipment that require high stiffness and axial load capacity.
