NTN HMK1521LL is a drawn cup needle roller bearing built with double seals to keep contaminants out and retain lubricant at the rolling elements. It measures 15 mm inside diameter, 22 mm outside diameter, and 21 mm width, giving it a compact, low-profile footprint suited to tight radial installations. The sealed design reduces maintenance needs compared to open-style needle bearings. Sold by Pro Gear and Transmission as a genuine NTN part.
