High-quality 6061 machined aluminum components (created in our machine shop in Rocklin, CA), are combined with smooth-rolling ball bearings and durable 3-inch Du-Bro pneumatic rubber tires. The dual independent tire design reduces vibration and drag, as well as increasing its load-carrying capacity. This caster wheel kit is designed to be completely maintenance-free, and should deliver long life and consistently high performance. The durable, sealed pneumatic tires are low-bounce and provide a smooth ride, even on rough surfaces. This Caster Wheel Kit is designed to work well with our Motor Mount and Wheel Kit AL (precision- machined 6061 machined aluminum 28962) as well as our injection molded plastic version - the Motor Mount and Wheel Kit -MP ( 28963) which both include our dual Quadrature Encoder sets ( 29321). The top surface of the Caster Wheel Kits mounting plate and the top surfaces of the motor bearing blocks in the Motor Mount and Wheel Kit AL and Motor Mount and Wheel Kit -MP are all designed to be at the same elevation, which simplifies chassis design, whether you choose to create your own, or incorporate into our Arlo Robot Base Kit ( 28960).
