IKO Machined Type Needle Roller Bearing METRIC RNA49/22, 28mm Bore, 39mm OD
IKO Machined Type Needle Roller Bearing consists of solid outer ring, rollers and retainer, without inner ring. They are with low sectional height, large load ratings and rigidity, and most of them come with seals. Prepacked lubricant is not provided except double sealed bearings (suffix UU). Proper lubricant must be applied when they are used. Machined Type needle roller bearings are generally used with shafts without inner rings. 0.2µmRa or less shaft surface finish and HRC 58 to 64 shaft hardness are recommended. When these requirements are not possible, use of IKO Inner Rings are recommended.
