Universal 11mm Stem Fit

These 3-inch roller-blade casters use a standard 7/16-inch grip-stem that fits 99 percent of office, desk, gaming and study chairs. Installation requires no tools; simply pull the old wheels out and press the new ones in within seconds. The stiffened bracket distributes load evenly across the dual ball bearings for long-term durability.

Not for IKEA or Threaded-Stud Chairs

Buyers whose chairs use 11mm threaded studs instead of a plain grip stem cannot use this set. The wheels are also not recommended for high-pile carpet because the soft polyurethane tread sinks and rolls poorly on deep fibers. Anyone needing a larger diameter or a different stem pattern should look elsewhere.

650 lb Total Load Capacity

The five-wheel set is rated to support up to 650 lbs combined, making it suitable for heavy-duty daily use on hardwood, tile, vinyl and low-pile carpet. Premium polyurethane treads roll silently and protect floors from scratches without requiring a separate chair mat.

Questions about this item

What does the 650 lbs total load rating mean for daily use?

The set of five wheels is tested to support up to 650 lbs combined, so a typical occupant plus chair weight stays well within the limit for long-term daily use.

How does the 11 mm stem interface work and what does it cap?

The 11 mm smooth stem pushes straight into the chair base socket; it fits 99 % of standard office and gaming chairs but will not work with 1KEA models that use a different stem size.

What clearance and floor type does the 3 inch diameter need?

Each wheel measures 3 inches in diameter, rolls on hardwood, tile, vinyl and low-pile carpet, and requires no tools — just pull the old casters out and press the new ones in.
