Needle bearings with guide ribs with inner ring

Demand For more informations contact us

Needle bearings without inner ring and with inner ring are the roller bearings for high loading with simple spatial construction. Needle rollers guided evenly to the axis in fix cage are made with tolerance diameter of 2 µm. Outer ring with ribs and a cage with needle rollers create the construction unit.

Needle bearings with ribs with inner ring are supplied in following design: NKI, NKIS, NA48, NA49, NA 69.

 

The design with inner ring is used when the raceway cannot be made on the shaft. Outer ring with a cage and inner ring may be assembled independently. The shift values (“s”) specified in the dimension tables cannot be exceeded in view of the manufacturing tolerances and the thermal expansion of connecting elements during operation. If the table values are insufficient, needle bearings may be combined with wider IR and LR rings, as shown in the dimension tables. For lubrication purposes the bearings have a lubrication groove and opening, this does not apply for bearings NKI d ≤ 7 mm.
