Heavy Duty Caster

K61​‍​‌‍​‍‌ series Heavy duty casters 900kg gocarts for heavy use of KoCo, a single wheel has a load capacity of 680-900kg. At the center, there is a 9mm drop forged steel top plate and an 18mm hydraulically riveted center pin, combined with the double-layer raceways hardened by heat treatment. Applications to automotive stamping lines, steel mines, and heavy mold handling made them a solid structure that supports high-intensity powered towing applications.

The K82 series dual swivel caster has a very competitive Kingpinless rotating structure, which totally removes the central bolt that may crack from high-load impacts. The double-row precision raceways are directly machined onto a 14mm drop-forged steel base plate. Thus, it is suitable for aerospace industries, automotive assembly lines, and heavy energy equipment. Directly delivered from the KOCO brand factory with an efficient delivery of 15-30 days, guaranteeing complete safety during the movement of ton-level equipment!

K83 Ultra-Heavy duty dual wheel nylon caster: Single wheel load capacity up to 10000kg (10 tons). Features a 16mm extra-thick forged steel base plate and 14mm reinforced bracket, with a core Kingpinless (pinless) double-row raceway precision machined structure. The dual-wheel design significantly increases the load capacity while providing excellent driving stability. Designed for the world's most demanding heavy industrial applications such as shipbuilding, wind power generation, and aerospace equipment handling. Direct supply from KOCO factory, efficient delivery in 15-30 days!

KoCo K75 Kingpinless 5000kg heavy duty caster has a carrying capacity of 2300kg-5000kg. Equipped with a 16mm thick base plate of industry-leading standard and a 30mm ultra-strong axle bolt, it is ensured that there is no center pin breakage under heavy impact conditions. Under these conditions, they can be used for aerospace, large equipment, and 5-ton mold applications. Factory direct supply, performance at heavy industry level.

The K53 casters can carry a load of up to 4000kg. It's standard to have a 20mm tank-grade ultra-thick top plate and a 40mm giant precision central pivot pin. The rotation system has a "plane bearing + thrust bearing" dual heavy-duty structure, and the raceway is precision machined and hardened, making the product suitable for aerospace, automotive assembly, and ton-level heavy-duty handling. Factory direct supply by the KOCO brand, delivery in 15-30 days.

K221 Series heavy duty casters with brakes: single wheel load capacity 200kg - 300kg. The K221 series redefines the balance of "mobility and stability" for equipment. It utilizes a one-of-a-kind integrated die-cast aluminum alloy support block, which greatly enhances the strength of the caster. The most notable technological innovation is in the clever "fixed adjustable brake handle" arrangement, which can be used in automotive assembly lines, storage cages, or aerospace precision instrumentation.
