Industrial Needle Roller Bearing 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.
