Office Chair Lubricating Grease
For lubricating office chairs, Klüber Lubrication ra44-3500 fully synthetic special damping grease can be selected, or other suitable lubricants can be chosen according to the material of the components. The specific lubrication plan should be selected in a targeted manner based on the material and functional requirements of the office chair components. The following is a detailed explanation:
Klüber Lubrication ra44-3500 fully synthetic special damping grease is a special lubricating grease designed for electrical appliances, car sunroofs, and seats. Its core characteristics include a soft feel, noise reduction, and high compatibility with plastic materials. This product reduces component friction through molecular-level lubrication technology while forming a stable lubricating film, effectively extending the service life of plastic or composite material components. Its damping characteristics can also adjust the resistance of the office chair's rotation or lifting, enhancing user comfort, and are especially suitable for plastic joints, slide rails, and other parts.
For metal joints, it is recommended to use sewing machine oil or WD-40. Sewing machine oil is a mineral-based light lubricating oil with strong fluidity, which can quickly penetrate metal gaps, reduce friction noise, but requires regular reapplication to maintain effectiveness. WD-40 combines cleaning and lubrication functions, and its solvent components can dissolve metal oxide layers, restoring joint flexibility, suitable for rusty components that have not been maintained for a long time. Note that excessive spraying should be avoided to prevent oil stains from remaining.
For wooden joints, it is recommended to use paraffin wax or furniture wax. Paraffin wax fills the gaps in wood fibers after melting, forming a waterproof sealing layer to prevent wood from cracking due to humidity changes while reducing rotational friction. Furniture wax adds natural beeswax ingredients, enhancing the gloss of the wooden surface on the basis of lubrication, suitable for the maintenance of high-end solid wood office chairs. Before use, ensure that the wooden surface is dry and clean to avoid wax layer peeling.
Plastic components require the use of silicone-based lubricants. Silicone-based lubricants, with polydimethylsiloxane as the main component, are chemically inert, do not corrode plastics or rubber, and have a wide temperature resistance range (-50°C to 200°C). Its spray design can precisely cover small structures such as pulleys and adjustment knobs, forming a long-lasting lubricating film while avoiding dust attraction, suitable for high-frequency use scenarios.
As the core load-bearing component of an office chair, the hydraulic rod is recommended to use lithium-based grease, extreme pressure grease, or high- and low-temperature grease. Lithium-based grease has strong adhesion and can form a stable oil film on the metal surface, reducing wear during the extension and retraction of the hydraulic rod; extreme pressure grease adds extreme pressure additives such as sulfur and phosphorus, which can withstand high-pressure impacts, suitable for users with a larger body weight; high- and low-temperature grease ensures lubrication performance in environments ranging from -30°C to 150°C through synthetic base oil formulations, extending the service life of the hydraulic rod.
