Office Chair Cannot Rotate
If your office chair cannot rotate, you can troubleshoot and resolve the issue by following these steps:
Check and Clean the Wheels and Foreign Objects
After prolonged use, hair, threads, pet fur, and other debris can easily become entangled in the wheel axles, causing them to jam. Lay the chair down or tilt it, carefully inspect each wheel, and manually rotate them to check for smooth movement. If you find any blockages, use tweezers, the tip of scissors, or a crochet hook to carefully remove the entangled material. Also, check the floor condition; thick or rough carpets can increase resistance, so temporarily move the chair to a smooth surface to test its rotation.
Check and Tighten Screws and Connectors
Prolonged weight-bearing and frequent rotation can cause the screws on the chair's bottom connectors to loosen. Focus on checking the connecting screws between the five-star base and the central swivel plate (usually located at the bottom of the plate) and the fixing screws for each wheel mount. Use an appropriate screwdriver (such as a Phillips or hex key) to inspect and tighten each screw appropriately. Be careful not to overtighten, as this can cause the screws to strip.
Lubricate the Swivel Plate Bearings
If the chair still rotates stiffly or does not move at all, the issue may lie with the base swivel plate. The ball bearings and sliding grooves inside the plate can become rusty and jammed due to dried-up grease or dust infiltration after long-term use. Locate the gap between the plate and the base, aim the nozzle of WD-40 multi-purpose lubricant at the gap, and lightly spray to allow the lubricant to penetrate the bearings and friction areas, displacing moisture and loosening rust. Then, rotate the chair back and forth repeatedly to help the lubricant spread. Wait a few minutes, wipe off any excess oil with a cloth, and sit down to test if the rotation is smooth. You can also apply white lithium grease (recommended viscosity grade NLGI 2) to the track of the base swivel plate to improve flexibility.
Check for Damaged Wheels
Examine the surface of the wheels for wear, unevenness, or cracks. If the wheels are severely worn, you will need to replace them with compatible new wheels (available at hardware stores or online). When replacing, remove the old wheels from the axles, install the new wheels, and ensure they are securely fastened.
Check the Condition of the Axles
Loose or rusty axles on the wheels can cause blockages. First, check if the screws are loose; tightening them may resolve the issue. If the axles are rusty, spray rust remover onto the rust, wait for the rust to be removed, and then drip lubricating oil to reduce friction between the axles and the wheels, restoring smooth rotation.
Check the Gas Lift
Observe whether the gas lift is bent or deformed. If there is an issue with the gas lift, you will need to contact a professional repair technician or replace it with a new one, as attempting to handle it yourself may pose safety risks.
