Chair Wheels 75 mm Stem 11×22 mm

Nippon Labs CC-BL3 wheels replace standard office-chair casters with a 75 mm polyurethane tread on a solid steel bracket. The 11×22 mm stem fits most common sockets and each wheel carries up to 650 lbs. A set of five swivel casters refreshes a full chair without tools.

Silent Rolling on Mixed Floors

Soft polyurethane coating protects hardwood, laminate, vinyl, tile and carpet from scratches while the double-bearing hub keeps motion smooth and quiet. Powder-coated steel resists corrosion during daily rolling across varied surfaces.

Five-Piece Tool-Free Upgrade

The pack supplies five identical casters so every leg matches in height and roll resistance. Press-fit stems install in seconds by pulling the old wheels and pushing the new ones home; IKEA chairs are not compatible.

Questions about this item

How do I install the 11 x 22mm stem wheels on my office chair?

Pull the old wheels straight out of the chair base sockets, then press the new stems firmly in until they seat; no tools are required, but the stems will not fit IKEA chair sockets.

What maintenance will the double bearing casters need over time?

The sealed double bearings are maintenance-free; if rolling becomes stiff or noisy, simply replace the affected wheel — each wheel is a sealed unit with no serviceable parts inside.

At what load does the 650 lbs capacity limit become a concern during daily use?

The 650 lbs rating applies to the full set of five wheels; sustained loads approaching that total will increase rolling resistance and accelerate wear on the polyurethane tread and steel brackets.
