Enso Motion Hubless Office Chair Wheels, 5 Pack, 70mm 750lb, Mu Black

• CONFIRM YOUR STEM BEFORE YOU ORDER: 11MM (7/16") FRICTION GRIP. Pull one caster off your chair and check the post. If it's a smooth 11mm friction stem with a 1 inch sleeve, this is a direct swap, no tools and no hardware. That's the industry-standard mount on most premium ergonomic task chairs, high-end mesh chairs, and contract-grade office seating. If your chair uses a threaded post or a plate mount, these will not fit.
• BUILT FOR HARD FLOORS AND GLASS MATS, NOT JUST CARPET. Non-marking medium-durometer polyurethane tires roll clean on hardwood, vinyl, tile, laminate, sealed concrete, glass chair mats, and low-pile carpet. No scratching, no gouging, no black streaks in grout lines. One compound handles every surface in the room, so you can stop buying floor mats and stop swapping wheels.
• WHISPER-QUIET, NO DETENT, NO STICK. Twin-wheel hubless design on two sealed ABEC chrome steel precision bearings per caster. No clatter on hardwood, no hitch when the wheel pivots, and no flat spots after sitting overnight. The stock plastic casters on your chair do not do this, and neither do most rollerblade-style replacements.
• 150 LB PER CASTER, 750 LB PER SET OF FIVE. Rated for 150 lbs static load each, built on a glass-strengthened acetal frame with hubless construction that has no axle to trap hair and debris. Sized for executive and gaming chairs, heavier users, and rolling case goods like credenzas and file cabinets. Tested to ANSI/BIFMA X5.1-2011 protocols for commercial use.
• HUBLESS DESIGNER SILHOUETTE, FOUR ACCENT COLORS. Japanese-influenced open-ring profile that changes how the chair looks the moment it's on. Black frame with black, gray, white, or red inner ring. This is the finishing detail on a chair you already spent real money on.
