Needle roller bearings without inner ring RHA, NK type
Needle roller bearings without inner ring are suitable for parts with limited radial size. Since there is no inner ring, the surface of the journal that matches it is directly used as a rolling surface. This kind of bearing does not limit the axial displacement of the shaft or housing, and the limit speed is high. .
There are inner ring needle roller bearings NA, NI type
Since this kind of bearing has no ribs on the inner ring, the inner ring, the outer ring, a full set of needle rollers and cages can be installed separately without restricting the axial displacement of the shaft or housing. Since the needle rollers are separated by a cage, the friction is reduced, so it can be used in parts with high rotation speed.
RNA·RS, RNA·2RS; NK·RS, NK·2RS; NARS, HA·2RS; NKI·RS, NKI·2RS type
Needle roller bearings without inner ring or with inner ring with seal ring are solid ferrule needle roller bearings with single or double sides with synthetic rubber
Rubber sealing ring to ensure long-term lubrication.
No rib and no inner ring needle roller bearing RNAO type, because this kind of bearing has no inner ring, it is suitable for parts with limited radial size. The matching shaft diameter surface is directly used as the rolling surface, so the matching shaft diameter surface hardness is required. Not less than HRC60, the surface roughness Ra value is not more than 0.63Hm, this kind of bearing does not limit the axial displacement of the shaft or housing. Needle roller bearings without ribs and inner ring NAO type outer ring, inner ring without ribs NAO type needle roller bearings, because of the lack of ribs, the inner ring, outer ring, a full set of needle rollers and cages can be installed separately. Axial displacement of the shaft or housing is not restricted. Since the needle rollers are separated by a cage, the friction is reduced, so it can be used in parts with high rotation speed.
Full Complement Needle Roller Bearing with Inner Ring This kind of bearing has oil holes in the outer ring, which can be lubricated by oil supply from the oil holes in the outer ring, and has double ribs. The inner ring has no ribs and no cage. The inner ring and the inner ring can be installed separately. Outer ring and full complement needle rollers. Full complement needle roller bearings without inner ring are suitable for parts with limited radial size. Since there is no inner ring, the surface of the journal with the matching shaft is directly used as the rolling surface. Full complement needle roller bearings with inner ring or without inner ring are this kind of bearing. Axial displacement of the shaft or housing is not restricted. Because this kind of bearing does not have a cage, the needle rollers lack precise guidance when rotating, and the mutual friction is also large, and the limit speed of the bearing is low.
