Until now desk chairs have plastic casters attached, and I have always been worried that the flooring has become tattered. Unexpectedly cheap and sized things are being sold, the place you changed is very light and very satisfied. It is slightly smaller and can not be relied on, but it can be used without problems.
Because there was no dimensional inscription made by Nakabayashi which is thought to be the same type, I purchased it here. Urethane wheel changed to rubber wheels as it damages the flooring floor. It is quiet and well-behaved and very satisfied.
The old castor was made of plastic, because the scratches on the floor became anxious, we replaced it with rubber casters. Although the burden on the floor was alleviated, I was glad that there was some kind of bigger size.
Since the plastic caster of the working chair in use was broken, I replaced it for this caster. Since it is made of metal, it is expected to have durability. Because the price was cheaper than the original one, I plan to exchange it for this if the casters of other chairs are broken.
Purchased as a caster of Daikin's air purifier MCK 70 MY. Measured the mouth of the air purifier to make this product was perfect. Even if you buy four, it is cheaper than genuine and it is quiet with flooring as it is a rubber wheel. Since there is no stopper, it may start moving if there is a slope. That rolling is smooth.
