INA NK45/20-TV-XL is a compact, single‑row needle roller bearing with machined rings in the XL variant, designed for high radial loads in tight spaces and without an inner ring. It has a 45 mm bore, 55 mm outside diameter, and 20 mm width, with an approximate weight of 0.25 lb (about 0.11 kg). This bearing is well suited to mechanical‑system applications that demand a small footprint paired with robust radial capacity.
