GQZ NART5 Non-Separable Needle Roller Track Roller Bearing 5×16×12mm Crowned Outer Ring Optional

NART5 is standard IKO type non-separable yoke needle roller track roller (roller follower). It adopts integrated thickened outer ring and built-in needle roller assembly, designed for inner ring fixed, outer ring rotating operation, rolling directly along guide rails or cam surfaces.

Common variants:

• NART5:Open type, no seals
• NART5UU:Double-sided rubber contact seals
• NART5R:R500 crowned outer running surface
• NART5X:Flat cylindrical outer surface

Mainly withstand radial loads; crowned outer surface can compensate minor installation misalignment and reduce edge stress. Open version supports periodic re-lubrication; sealed version keeps internal grease for long maintenance-free operation. Widely used on miniature automated equipment, printing machinery, packaging lines, textile machinery and light-load cam transmission structures.
