Need a tough, compact bearing for high-load applications? This Koyo B-166 needle roller bearing is built to handle it. It's a full complement drawn cup type, which means it packs more rollers into a smaller space for higher radial load capacity than caged bearings. The dimensions are 1 inch inside diameter, 1-1/4 inches outside diameter, and 3/8 inch width – perfect where space is tight but strength is needed. Made from through-hardened, high-carbon chromium steel, it stands up to heat and heavy dynamic loads, with a max speed of 4300rpm. It meets ASTM F2162 standards, so quality is assured. You'll find these in automotive transmissions, construction equipment, pumps, and all sorts of industrial machinery. If you're replacing a worn bearing or designing something that needs reliable rotation under pressure, this Koyo bearing is a professional-grade choice that won't let you down.
