The set is aimed at facilities and users who move loads outdoors or over uneven surfaces and want pneumatic tread that reduces vibration. The standout reason to buy is consistent rollability under load, thanks to pressurized pneumatic cores and ball bearing hubs that keep the wheels inflated and rolling even on wet grass or rough ground.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e8 in pneumatic wheel:\u003c\/strong\u003e The pneumatic rubber tread and pressurized inner core provide a cushioned ride and better shock absorption on uneven surfaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e300 lb per caster capacity:\u003c\/strong\u003e Each caster supports up to 300 lb for a combined total of 1,200 lb, making the set suitable for medium to heavy duty carts and equipment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop lock brakes:\u003c\/strong\u003e The included top locking brakes deliver positive locking against the wheel top for secure parking on inclines and irregular flooring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt on swivel locks:\u003c\/strong\u003e Field-installable bolt-on swivel locks convert a swivel caster to rigid tracking for controlled straight-line movement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZinc plated finish:\u003c\/strong\u003e Corrosion-resistant plating helps these casters hold up in demanding environments while maintaining smooth bearings and roll performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlate mount compatibility:\u003c\/strong\u003e A 4 in x 4 1\/2 in top plate with common bolt patterns lets the casters be bolted or welded to a wide variety of frames.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe set is best for maintenance teams, catering or food service carts, luggage and outdoor utility carts that encounter grass, gravel or uneven concrete and need quieter, smoother rolling than hard wheels provide.
