These twin‑wheel suspension casters are built for heavy industrial use, combining strong load capacity, stable performance, and long service life. Here are clear, user‑friendly and professional advantages:

Superior Shock Absorption
Built‑in suspension structure effectively absorbs vibration and impact, protecting equipment, cargo, and floors during movement—ideal for uneven ground and heavy loads.
Heavy‑Duty Load Capacity
Available in Ø100, Ø150, Ø200 mm sizes, with load ratings up to 350 kg per caster. Strong enough for industrial trolleys, machinery, racks, and heavy equipment.
Dual‑Wheel Stability & Balance
Twin wheels spread weight evenly, lower center of gravity, reduce sway and tipping risk. Both wheels stay grounded for safer movement under full loads.
Smooth & Quiet Rolling
Dual ball bearings ensure low friction and easy swiveling. PU + PA wheels roll quietly, leave no marks, and reduce wear on floors.
Strong & Durable Construction
High‑strength bracket and rigid wheel core resist deformation. Quality materials extend service life and lower maintenance costs in harsh working conditions.
Versatile Mounting & Compatibility
Standard top plate mounting with fixed hole spacing, easy to install on industrial carts, AGVs, machines, and heavy handling equipment.

These casters deliver stability, safety, and durability for heavy‑duty applications.
