JQR263

PRODUCT OVERVIEW Two-Stage Suspension Caster for AGV & AMR Systems The JQR263 is a heavy-duty passive swivel caster designed for AGV, AMR and automated material-handling equipment operating on uneven industrial floors. Its two-stage suspension system combines dual coil springs for primary shock absorption with a polyurethane damping block for secondary impact control. This structure helps reduce vibration transmitted to the vehicle while maintaining stable wheel contact across floor joints, small obstacles and uneven surfaces. 350–450 kg Load Capacity 100–150 mm Wheel Diameter 50 mm Wheel Width 5.4 km/h Rolling Speed −25 to +70°C Operating Temperature ENGINEERING FEATURES Designed for Stable Automated Travel The suspension, wheel and swivel structure are designed to support repeated industrial operation while reducing shock transmitted to the AGV or AMR chassis. 01 Two-Stage Shock Absorption Dual coil springs absorb the primary impact, while a polyurethane damping block provides a secondary stage of vibration control. 02 Stable Floor Contact The suspension responds to changes in floor height, helping maintain consistent wheel contact on uneven industrial surfaces. 03 Industrial Polyurethane Tread Shore 93A polyurethane combines wear resistance, dimensional stability and controlled rolling performance for indoor industrial applications. 04 Heavy-Duty Swivel Structure A pressed-steel fork with zinc-plated surface treatment provides a durable supporting structure for repeated steering and travel.
