The set of four supports a total of 1,000 lbs, making it suitable for luggage carts, food carts, garden carts, and other utility platforms where shock absorption and smooth roll matter. The single biggest reason to buy is the pneumatic rubber wheel construction, which provides quieter operation and better traction on uneven outdoor surfaces compared with hard wheels.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel construction:\u003c\/strong\u003e Pneumatic black rubber tread with a pressurized inner core keeps tires inflated under load for consistent cushioning and shock absorption.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad capacity:\u003c\/strong\u003e Each 6 in caster supports up to 250 lbs, so the set carries a combined 1,000 lbs for medium duty applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting plate:\u003c\/strong\u003e The 4 in x 4 1\/2 in top plate with multiple bolt hole patterns allows bolting or welding to a wide variety of frames.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrakes:\u003c\/strong\u003e Includes bolt-on swivel locks that convert a swivel caster to rigid tracking for straight-line stability when needed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing performance:\u003c\/strong\u003e Ball bearing hubs help the wheels roll smoothly and reduce noise for improved maneuverability on different surfaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish and durability:\u003c\/strong\u003e Zinc plated hardware resists corrosion and supports long-term use in shop and outdoor settings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThese 6 in swivel pneumatic casters are best for small businesses, maintenance teams, and DIYers who move moderate loads around shops, outdoor grounds, or event setups and value a smoother, quieter ride over rough surfaces.
