Description Model 30 Swivel Casters are a step up from swivel caster model G15 in that it features larger swivel and wheel bearings and wider wheels. The precision machined swivel provides superior performance on both manually moved and mechanically powered equipment. The metal frames are zinc plated for rust resistance, and there are lubrication fittings for all moveable parts. Popular options include a face contact wheel brake to lock the wheels and a hand operated swivel lock that converts a swivel caster into a rigid caster for direct line travel. Capacity up to 7,000 pounds per caster. Model 30 features a large swivel and wheel bearing which allows for heavy loads and more arduous service. Benefits include easier swiveling, reduced swivel vibration, and longer trouble free performance. Ideal for steel mill operations, foundry equipment, and die and mold transport. Caster City manufactures this caster and it is also available in 304 Stainless Steel as the SS-30 for wet or corrosive applications.

Phenolic can not develop a flat spot if left parked for a long period under load, and the wheel is capable of withstanding shock loads and the impacts of small obstructions. Phenolic wheels are a hard composition, non-marking wheel designed for supporting large loads comparable to a metal wheel. Phenolic can absorb water and other chemicals if excessive exposure occurs, so this wheel is best suited for dry environments. Phenolic caster wheels come standard with a roller bearing and have precision sealed ball bearings as an option. All phenolic wheels have a Durometer of Shore D 90 and the temperature range is -40°F to 250°F. Ideal for warehouse storage equipment, manufacturing floor carts, and heavy stationary fixtures. *This Plate Caster Model 30 contains Phenolic Swivel Wheel.
