LM249747NW/LM249710CD TDO Double‑row Tapered Roller Bearing 253.975×347.663×101.6mm Heavy‑Duty Mining Industrial Equipment Spare Part

LM249747NW/LM249710CD is an inch‑size heavy‑duty TDO double‑row tapered roller bearing, consisting of two separate cone assemblies and one shared double outer cup. It can withstand large combined radial and bidirectional axial loads with excellent shock‑resistance and high rigidity. Optimized internal geometry delivers stable, low‑friction running and long service life for harsh continuous‑operation industrial environments. Its separable cone‑and‑cup‑structure brings convenience for installation, inspection and maintenance.
