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.

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.
