We manufacture drawn cup, full-compliment needle bearings
in NA / NK/ NKI and NKIS types. They have a deep-drawn cup with a full
compliment of needles. In a few needle bearings, the needles are retained by
the cup lips and in the others they are retained by grease. In the grease
-retained needle bearings , we generally use spherical -ended rollers. Drawn
cup needles have higher speeds and reduced load bearing capacity. They are a
good tolerant to for misalignment. These heavy- duty needle bearings have a
heavy outer ring which increases load capacity. The rollers are cylindrical
rather than being tapered and hence problem of slippage is faced between the
roller and raceway surfaces.
