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!

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.

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.

KoCo K31 Industrial polyurethane wheel: Single wheel load capacity up to 250kg. Includes industry-leading 4.0mm ultra-thick brackets and 12.8mm reinforced rivets. The swivel track is heat-treated and quenched, which results in a lifespan increase of 50%. Purchase factory direct with a one-year warranty.

K361‍‌‍‍‌ Dual wheel agv caster: One wheel can support loads up to 2000kg (2 tons). They are suitable for heavy-duty AGV, digital warehousing, and new energy vehicle assembly lines. The unique "dual-wheel + composite bearing" structure of this model not only guarantees millimeter-level steering accuracy but also supports ton-level load capacity.

K222 Double brake caster: A single wheel can bear a load of 200kg – 300kg. They can be used for high-load automated production lines, intelligent robots, and AGV unmanned guided vehicles. Being the flagship model directly sold by the KoCo brand, we commit to factory direct supply and a fast delivery cycle of 15-30 days.

The​‍​‌‍​‍‌ KoCo K41 series heavy moving castor is able to carry a single wheel load of 500-800kg. It has a 6-8mm thickened top plate and an 18/24mm kingpin, which is built to be strong. The heat-treated double raceway ensures very smooth swiveling. The standard setup is cast iron core polyurethane wheels (PI/UC). Factory direct supply, OEM customization is ​‍​‌‍​‍‌available.

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.

K42 series are adopting rolled steel, with deeply formed rotarytracks and heat-treated surfaces, resulting in excellent wear resistance,it is suitable for power towing. They are specifically designed for harshworking environments. Their large-diameter center-hole bolts andtracks disperse vibrations over a wide range while increasing stressresistance Salt spray test completed in 72 hours. Suitable for low-speeddynamic traction under medium loads (speed not exceeding 5 km/h).

K422 Polyurethane aluminum core wheel: Single wheel load capacity ranges from 100kg to 200kg. They can be used in various fields such as AGVs, intelligent robots, and automotive assembly lines. As the KoCo brand's 25th anniversary and direct factory supply in the series, we provide efficient global delivery within 15-30 days, thanks to our 50,000㎡ intelligent manufacturing capabilities. Its rotating raceway is made of top-grade 65Mn hardened steel, which ensures the caster has an extremely low center of gravity while at the same time the caster achieves industry-leading wear resistance and handling sensitivity.
