Products / Heavy-Duty Sliding Door Rollers
Heavy-duty rollers are built for heavy door panels: the carries 120KG per door (vs ~60KG for standard rollers); the dual-wheel set distributes force more evenly, suited to solid-wood doors and large-panel partitions.
120KG is the static rating; for dynamic load, plan at 70% of the rating.
Heavy-duty models should use ball bearings (not oil-impregnated bearings) — state this clearly when quoting.
Heavy wheels require a thickened hanging track (≥1.5mm); pairing them with a light track accelerates wear.
Of the 59 verified factories in this library, 36 are in Zhongshan Xiaolan — China's most concentrated door-hardware cluster. These products can be discussed directly on WhatsApp for specs, MOQ and sampling.
