Description Model 30 Swivel Casters are a step up from swivel caster model G15 in that it features larger swivel, wider wheels, and wheel bearings. The precision machined swivel provides superior performance on both manually moved and mechanically powered machinery. The metal frames are zinc plated for rust resistance, and there are greasing 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 shipyard operations, oil and gas equipment, and mining operations. Caster City manufactures this caster and it is also available in 304 Stainless Steel as the SS-30 for wet or corrosive applications.

Caster City has designed the “PYH” industrial caster wheel to come with an extra thick ¾” polyurethane tire that is bonded to a heavy iron center for higher load ratings and a longer life of the product. The industrial caster wheel “PYH” is excellent for supporting heavy loads and can take more abuse than standard polyurethane wheels in its size. The “PYH” industrial caster wheel comes standard with tapered roller bearings, but also has precision sealed ball bearings or a roller bearing as an option. The “PYH” industrial caster wheel is available in diameters from 6″-12″ and the wheels are available in 3″ or 4″ wide. The durometer of this industrial caster wheel is Shore D 60 ( /- 5) and the temperature range is -40° F to 180°F. Ideal for forging operations, press and stamping equipment, and industrial oven and furnace carts. *Photo of this Polyurethane on Iron Wheel – Heavy Duty Swivel Caster Model 30 uses the 6″ x 3″ wheel.
