Description
Caster City’s Model 3 is a swivel stem caster with stamped steel construction and a bright zinc plated finish for corrosion resistance. This stem caster inserts into equipment socket holes instead of a bolt-on plate. Grip ring, threaded, expanding adapter, and square and round metal stems are offered. Two rows of ball bearings on hardened raceways ensure smooth and reliable swivel action. A metal dust cover over the swivel raceways keeps dirt and dust from contaminating the bearing surfaces. The wheel rides on a 3/8″ diameter bolt axle with lock nut and the swivel is held together by a 1/2″ diameter rivet. Capacity up to 350 lbs per caster depending on stem type. Uses 1-1/4″ wide wheels. Multiple wheel and brake options are offered. Ideal for hobby shop carts, model building stations, and craft supply storage with tubular frames. NSF listed.
High Temperature Phenolic wheels are non-marking, hard composition wheels made from glass strands, making them an excellent choice for your bakery or oven application. The High Temperature Phenolic caster wheel is best suited for dry heat applications such as powder coating, dry heat bakery ovens, dry heat autoclaves and more. High Temperature Phenolic caster wheels make an excellent, low cost choice for supporting loads as they roll into and out of an oven. Caster City has designed this caster wheel to have the following temperature range: up to 475°F for continuous use, 525°F intermittent. If used above 475°F for more than 30 minutes continuous operation it will reduce the life of the wheel. These wheels have a hard surface and should be used on smooth floor surfaces. It is always best to shield High Temperature Wheels from a direct heat intake source. Caster City can furnish high temperature phenolic wheels with a plain bore, straight roller bearing, or oilite bronze bearing sleeve. Ideal for dry heat autoclaves, powder coating facilities, and commercial bakery ovens.
