SKF NU307 cylindrical roller bearing is a single-row bearing with a straight bore of 35 mm, an outer diameter of 80 mm, and a width of 21 mm, designed to withstand radial loads in compact installations. It is available in multiple suffix variants—NU307 ECP, NU307 ECM, and NU307 ECJ—reflecting different internal clearance and mounting configurations; for example, NU 307 ECP is cataloged with C0 internal clearance. The 35×80×21 mm footprint is a standard size that supports straightforward replacement in compatible shafts and housings, while variants with higher clearance (such as C3) are also offered to accommodate varying fit and preload requirements.
