Description
Model 30 Swivel Casters with Polyurethane on Iron with Precision Bearings are an improvement from the Model G15. The precision machined swivel provides unmatched performance on both manually moved and mechanically powered machinery. The metal frames are zinc plated for rust resistance, and there are lubrication fittings for all adjustable parts. Popular options customers like to include a face contact wheel brake to latch the caster wheels and a hand operated swivel lock that converts the swivel caster into a rigid caster for direct line travel.
The PYH – Extra Thick Heavy Duty Polyurethane on Iron Core Wheel for the Plate Caster Model 30 is a heavy duty industrial caster wheel designed to carry higher load capacities than standard polyurethane wheels in its size thanks to its extra thick ¾” polyurethane tire bonded to a heavy iron center. Available in diameters from 6” to 12” with tread widths of 3” or 4” this wheel supports up to 5000 lbs for 12” x 3” 4000 lbs for 10” x 3” 4000 lbs for 8” x 3” and 3000 lbs for 6” x 3” with a Shore D 60 durometer tire operating from -40°F to 180°F. It comes standard with tapered roller bearings but can also have roller bearings or precision sealed ball bearings for smooth towing of heavy loads in settings like steel mills or power plants.
The PYH – Extra Thick Heavy Duty Polyurethane on Iron Core Wheel’s extra thick tire and harder durometer make it excellent for supporting heavy static loads and taking more abuse than standard polyurethane wheels in its size perfect for heavy carts or machinery in industries like chemical plants or mining operations. Its heavy iron center ensures a longer life while the variety of bearing options lets you pick the best performance for your application though the tire’s chemical bond can weaken from overloading heavy impacts or heat from continuous use. Paired with the Model 30’s zinc-plated steel frame this heavy duty kingpinless caster is a top choice among industrial casters and wheels for heavy duty plate caster applications needing durability and reliable performance in dry conditions like oil rigs or logistics hubs.
