Details:

Bearing type: Machined needle roller, no inner ring RNA series. This is genuine JNS New Old Stock from Japan. The bearing is factory-new, unused, and in full working condition. JNS RNA 4906 Machined Needle Roller Bearing No Inner Ring.

Outer ring: Lubrication hole on outer ring. IMPORTANT: This listing is for ONE 1 bearing. Brand: JNS Japan Part Number: RNA 4906 condition: NOS New Old Stock, factory-new and unused. The RNA designation means the bearing runs directly on a hardened and ground shaft, which serves as inner raceway saving space reducing cost in applications where shaft is already suitable.

This is the standard open variant. Original packaging may show shelf wear, dust, or minor cosmetic flaws from long-term storage. Please verify this part number, dimensions, and configuration RNA no inner ring; bearing runs directly on hardened shaft match your application before purchasing. The needle rollers are guided by a steel cage within machined outer ring.

Needle roller bearings deliver exceptionally high radial load capacity in a compact cross-section, making them essential where space is limited but loads are heavy. The JNS RNA 4906 is a machined-ring needle roller bearing without an inner ring.
