PRODUCT OVERVIEW
The KU Series 5 Inch Dual Spring Shock Absorbing Caster is the "Goldilocks" size of the range — the most versatile wheel for mid-weight industrial equipment. The red polyurethane tread on a solid cast iron core delivers floor protection and load capacity, while the galvanized steel bracket shrugs off humidity and corrosion.
At 350kg per wheel (1,400kg on a 4-wheel set), the KU-5 handles mainstream workshop machinery with ease. The dual-spring suspension absorbs floor irregularities and equipment vibration, making it the default choice for laser cutters, woodworking machines, electrical cabinets, and welding tables.
