How to fix or repair swivel chair noise, squeaks, rocking, tipping, floor spotting, greasy spots, gray powder,
falling out ball bearings
Unparalleled product knowledge
Virtually all your problems are usually being caused by Metal rubbing against Metal. This only occurs when a part has worn out either from use, abuse or deterioration (includes breakage) of a metal or non-metallic part(s) permitting the rubbing.
Since worn out (away) metal cannot be replaced, the only real "fix" is a replacement in most instances!
Since broken assembled parts for Gas mechanisms are not replaceable, the only real "fix" is a replacement! Only the Gas (lift) adjustable height cylinder can be replaced.
Since broken parts for Manual mechanisms are not replaceable, the only real "fix" is a replacement! Only the threaded Post, Bell and Thrust washer can be replaced.
Since Bar stool swivels wear out and those having plastic or metal races or springs which break cannot be replaced, the only "fix" is a replacement! Ball bearings cannot be put back into place. The metal has worn away (now on the floor) and they will fall out again shortly) or the plastic race (ball bearing retainer) has broken.
The only exception to all of the above is an all wood Chair seat and/or back or floor chair base. Noise and squeaking can occur when a wooden joint has loosened due to glue failure (stress) or loose and broken dowel pins or loosened screws. See a competent furniture repair shop.
Welding broken metal (fatigue) cannot be successfully welded with any permanency. The weld heat usually causes damage to other parts, increasing the cost of the imminent replacement of the initially worn out part, and usually fails again shortly. Simply put, the weld might be good but the metal cannot take the damaging heat.
