KoCo K72 Kingpinless polyurethane caster, with a single-wheel load capacity of 1000kg-2700kg. The 9mm thickened base plate, paired with a heat-treated precision raceway, completely rules out the possibility of a fracture under heavy loads. Made specifically for heavy-duty use, such as aerospace and automobile manufacturing. Factory-direct supply with better performance than traditional bolted structures.

These amazing KoCo K62 series supersized heavy-duty forged steel nylon caster wheels have a super stable weight carrying capacity of around 1000-1100kg. They boast a top plate made of 9mm double-layer thickened forged steel and a 19mm hydraulically riveted center pin. These features give great power, traction performance, and UWB brakes, and PSL directional locking customization can be supported as well.

KoCo K52 heavy duty nylon caster are maintenance-free, and their single-wheel load capacity ranges from 400kg to 2500kg. thickness of the machined top plate has been taken up to 12mm, which contributes to the excellent impact resistance and smooth rotation of the casters. They are mainly used in the aerospace, heavy mold transfer, and automotive manufacturing industries.

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.

K32​‍​‌‍​‍‌ Polyurethane on iron wheel: A single wheel load may reach 420kg. Besides this, a 5.5mm super-thick reinforced bracket and a 15.8mm huge central rivet are some of the main features. The swivel raceway is heat-treated and hardened, source factory with 25 years of experience, and direct delivery from stock.

The​‍​‌‍​‍‌ KoCo's K51 series polyurethane on iron wheel has a load capacity ranging from 460 to 1500kg. Some of the features that eliminate the need for frequent maintenance while still allowing very smooth rotation even under heavy loads include a machined top plate and a combination "plane bearing + thrust bearing" structure. The product is very suitable for aerospace mold handling.

This omnidirectional wheel features a rolling bearing design,and the passive rollers are surfaced with polyurethane.With a compact structure and smooth, agile movement, it isan ideal all-direction wheel suitable for both indoor and outdoorapplications.

K421 low-center-of-gravity precision dual-wheel aluminum core caster single wheel load capacity 180kg-200kg. Perfect for AGVs, intelligent collaborative robots, and aerospace equipment handling in confined spaces, but still with a requirement of a heavy load capacity. By employing a precision single bearing as the swivel center together with a high-quality polyurethane cushioning structure, Aluminum PU caster achieves extremely low center of gravity stability and still provides excellent shock absorption for the safe and stable operation of precision instruments.

K451 Casters: Each unit can carry a 250kg - 630kg load. Suitable for heavy-duty AGVs, collaborative robots, and aircraft assembly lines. Being the flagship series of the original KOCO brand factory, our 50,000㎡ intelligent manufacturing capabilities guarantee efficient worldwide delivery within 15-30 days.

K441 Industrial High-Speed 20km/h caster: Single-wheel load capacity 280kg - 450kg. The K441 series represents the peak of technology, capable of handling complex dynamic loads. Its rated operating speed is up to 20 km/h. Being the KoCo factory direct series with over 25 years of experience, our 50,000㎡ intelligent manufacturing center makes sure of efficient global delivery within 15-30 days.

K341 Heavy-Duty Precision Casters: Each single wheel can hold loads from 700kg up to 1000kg. Intended for heavy-duty AGVs, tow cart systems, and the high-frequency logistics of smart factories. Being a direct factory series under the KoCo brand, we utilize our 50,000㎡ intelligent manufacturing base to guarantee worldwide delivery within 15-30 days. The series is equipped with a premium heavy-duty composite bearing structure that can bear a pressure of 1 ton per wheel and allow for zero-resistance steering when underpowered towing, thus delivering a high level of performance and reliability for heavy industry automation upgrade.

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.
