5 Office Chair Casters 11 x 22 mm - Suitable for all floor types - 360° Silent Bearings. Abrasion resistant on hard floors and carpets - Universal Swivel Casters

【Smooth and Safe】 The office chair caster features a double-wheel design. The wider double wheel allows the caster to glide more stably and safely across the floor than a single wheel. You no longer have to worry about the chair slipping or constantly spinning. Furthermore, unlike single-wheel models, it won't put excessive pressure on the chair legs or damage them.

【Premium Casters】 The swivel office chair casters are made of 4 imported bearings and wear-resistant polyurethane. They are durable, quiet, and very convenient. With our rubber rollers, you'll glide silently across any floor. You won't disturb others.

【Suitable Height】 Our chair caster maintains the original office wheel design without increasing the chair's height. The height is 59 mm. Buy our office caster. You no longer have to worry about not being able to adjust the chair height, allowing you to sit much better and more comfortably. 【Scratch-Free Swivel】Whether you use our office chair casters on hard floors, carpets, tiles, or wood, the shock-absorbing casters made of enhanced polyurethane rubber will protect your floor from scratches and stains. You don't need an office chair cushion or floor mat, saving you money. 【Universal Shaft Size】The 11mm x 22mm replacement office chair casters are compatible with almost all office chairs.
