Old-style Office Chair Wheels

If the wheels of an office chair are old-style, the following situations may occur along with solutions:

Wheel Material and Performance Issues

Old-style office chair wheels are commonly made of hard plastic or ordinary rubber. Hard plastic wheels may slip on smooth surfaces due to low friction, affecting the user experience; on rough surfaces, they may generate significant noise and even cause wear to the floor due to their high hardness. Ordinary rubber wheels, while relatively soft, tend to age and harden over time, resulting in uneven rolling and stuttering. Solutions: For hard plastic wheels, if used on smooth surfaces, wrap a layer of anti-slip tape around the wheels to increase friction; if used on rough surfaces, place a soft rubber pad under the wheels to reduce noise and floor wear. For aged and hardened rubber wheels, try using a rubber softener; if the effect is unsatisfactory, it is advisable to replace them with new rubber wheels.

Wheel Installation Structure Issues

The installation structure of old-style office chair wheels may be relatively simple, typically involving a metal shaft directly inserted into a hole at the bottom of the chair for fixation. Over time, the metal shaft may wear down and become thinner, causing the wheels to loosen and wobble, affecting the chair's stability. Solutions: Use metal washers to increase the diameter of the metal shaft, ensuring a tight fit with the hole at the bottom of the chair, thereby resolving the issue of loose wheels. If the metal shaft is severely worn and cannot be fixed with washers, replace it with a new metal shaft and wheels.

Wheel Brake Function Issues

Some old-style office chair wheels may lack a brake function, or the brake function may have failed. Without a brake function, the chair can easily slide around during use, posing a safety hazard; a failed brake function prevents the chair from being fixed in place, affecting convenience. Solutions: If the chair originally lacked a brake function, consider purchasing wheels with a brake device for replacement. If the brake function has failed, check if the brake device is jammed with foreign objects, clean them out, and try adjusting the tightness of the brake device to see if the brake function can be restored; if the issue persists, replace the brake device or the entire wheel.
