Inline polyurethane castors - 5 pcs

Inline polyurethane castors are a versatile replacement wheel set for various types of chairs and seating. The 75 mm wheels feature a soft polyurethane tread that helps protect hard floors from scratches. The swivel design allows the chair to move in different directions while you work. The castors are suitable for saddle chairs, chairs with triangular seats, task chairs, gaming chairs and other chairs with compatible stem fittings. The grip-ring stem pushes directly into the socket in the chair base. The stem is 11 mm in diameter and 22 mm long. Check the stem dimensions of your existing castors and the compatibility of the fittings before ordering. The installation height from the base of the stem to the floor is 95 mm. Consider the castor height when replacing wheels, as a different wheel size may change the chair’s seat height. The product is sold only as a set of five castors, allowing you to replace all the wheels on a five-star chair base at the same time.
