Machined ring needle roller bearings NTN Machined Ring Needle Roller Bearings The machined ring of this bearing type contains needle rollers and a cage. And the outer ring and the needle rollers are inseparable from each other by means of double-side ribs on the outer ring or side plates. Because of its machined (solid) outer ring enabling to make it more rigid and to thereby upgrade the bearing accuracy, this bearing type is suitable for an application requiring high speed, high load and high running accuracy. These machined ring needle roller bearings are available in two types -- one without inner ring and another with inner ring -- considering the case of using a shaft as the direct raceway surface without using inner ring. Bearing type Applied shaft diameter (mm) Composition of nominal bearing number Remarks Type RNA49 712 Type NA49 RNA 49 5 T2 Tail code Bore dia. No. Dimension series Type code Bearing with tail code T2 uses a polyamide resin cage and, therefore, it shall be used at allowable temperature 120˚C and, under continuous running, at 100˚C and less. The dimension series is in compliance with JIS B 1512 or ISO 15. 59 [Tail code] T2: Resin cage Type RNA49R 14490 With seal 1458 RNA 49 02 R Tail code Bore dia. No. Dimension series Bearing with seal type (Tail code: L or LL) - synthetic rubber seal built in at single side or double sides is internally filled up with ithium soap base grease. Type NA49R 10440 With seal 1050 Type code [Tail code] R: Rib type L: Single-side seal type LL: Double-side seal type The sealed bearing type shall be used within the temperature range of -25 to 100˚C to prevent deterioration of the seal and filled-up grease. The dimension series is in compliance with JIS B 15 or ISO 15. B-54
