SKF NA4903.2RS — Needle roller bearing (machined rings)
SKF · Bearings & Power Transmission · Needle Roller Bearings
SKF NA4903.2RS needle roller bearing (machined rings). Needle roller bearing with machined inner and outer rings (NA48xx, NA49xx, NA69xx, RNA48xx, RNA49xx, RNA69xx per ISO 3245 / DIN 617). Ideal for high radial load in the smallest possible radial section — universal-joint yokes, camshaft supports, transmission planetary pinions. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options (material, sealing, cage, precision, clearance, lubricant). Genuine SKF supply carries the SKF logo etch or moulded mark and hologram-authenticated packaging.
