Caster City offers a high capacity Maintenance Free Industrial Caster, engineered for maximum uptime and superior performance in the most demanding environments. If your operation relies on continuous motion and minimizing labor costs, this is the ultimate solution. When your application demands uncompromising strength and reliability, choose these casters built for a zero-maintenance platform.
Zero Routine Maintenance: Completely eliminates the need for periodic greasing and associated production downtime and labor costs.
High Capacity Casters: Engineered with tapered roller bearings for radial loads plus thrust ball bearings for axial loads from tugging and high speed AGV operations.
Maximum Uptime & Reliability: Sealed precision bearings throughout the swivel assembly and wheels ensure sustained smooth rotation without operational disruption or maintenance intervals.
Extended Swivel Lead: Extended swivel lead allows wheels to roll into turns rather than scrub sideways, cutting the force needed to initiate direction changes by up to 30%. This geometry reduces both operator fatigue and AGV motor requirements when swiveling heavily loaded equipment from stopped positions.
Reduced Wheel Flutter: The same extended lead that eases turning also prevents high-speed wobble by increasing mechanical trail. The wheel strongly self-centers during straight rolling, pushing the flutter threshold above typical 5-7 mph towing speeds where standard casters develop destructive wobble or oscillatioin.
Crown Tread Wheels: Polyurethane wheels feature a crowned profile for point contact, dramatically reducing the lateral friction that sustains flutter. This design also lowers rolling resistance and provides superior floor protection compared to flat-tread wheels.
Durable Industrial Casters: 3/8″ thick top plate and 5/16″ double-welded legs that enable up to 2500lbs of capacity depending on the wheel.
