Concept and operating principle of double ball bearings

Dual ball bearings are an important step forward in the manufacturing technology of high-end office chair moving mechanisms. Unlike single ball bearings, which only use one row of rolling balls. Dual ball bearings are made up of two parallel rows of balls. They work simultaneously to distribute the load and minimize friction. When the wheel moves or rotates, these two layers of balls alternately share the force. This helps the movement become smooth, stable and vibration-free.

In the president’s office chair – where softness, durability and a luxurious feel are required. The double ball bearing is the “heart” of the wheel. This mechanism not only ensures smooth rotation. But also improves balance, limiting wear when the chair is under heavy loads for a long time. By distributing force evenly around the axis of rotation. The double ball bearing maintains absolute stability of the chair, even when the person sitting leans or rotates continuously. Thanks to these outstanding technical characteristics, the double ball bearing has become the standard for high-end executive chairs and meeting chairs.

Detailed structure and material of double ball bearing

The structure of the double ball bearing in the swivel chair wheel is meticulously designed down to the smallest detail. To achieve a balance between mechanical strength and high aesthetics. The outermost layer is the bearing shell, usually made of carbon steel or engineering plastics such as nylon PA6 or PU. This layer plays the role of protecting the entire internal mechanism from impact and pressure when the wheel moves on different surfaces.

Inside are two rows of small steel balls arranged symmetrically. They are precisely machined from stainless steel or chrome-plated steel. Helps reduce friction when rotating, while increasing service life. In the middle is the central shaft – the main bearing part. Usually hardened and treated against corrosion to ensure durability in humid or dusty environments. In addition, the bearing system and dust cover are sealed at both ends. To prevent impurities such as fabric fibers, fine dust or sand from entering the bearing. Ensure smooth movement. All these details work together harmoniously, creating a structure that is both durable and smooth. The decisive factor for the “smooth as gliding” feeling when the chair moves.

Application and value of double ball bearings in the design of chairman’s meeting room chairs 

In the design of executive chairs, dual ball bearings are not just a technical detail. They are also a factor that affects the overall user experience. Executive chairs often have strict requirements: smooth operation, high load capacity (usually 100–150 kg). And move smoothly on many different types of floors, without making noise. Dual ball bearings perfectly meet these criteria thanks to their ability to reduce vibration, distribute force evenly and have extremely low friction.

In addition to mechanical performance, this mechanism also brings clear aesthetic value. Thanks to the double ball bearings, the designer can reduce the size of the wheel. While still ensuring great load-bearing capacity. Helping the overall chair become more compact and luxurious. Users clearly feel the difference: the chair rotates lightly, moves smoothly and has absolutely no “squeaking” or “clacking” sounds commonly found in popular chairs. From there, the double ball bearings not only improve the quality of operation. But also contribute to shaping the class and majesty of the meeting room space of leading businesses.

2. Outstanding functions and benefits of double bearings in chairman’s meeting room swivel chairs 

The double ball bearing is not just a small mechanical part. It is also a factor that directly determines the quality of operation and the class of use of the president’s office chair. Thanks to the structure of two rows of rollers operating in parallel. This system creates extremely smooth and stable movement. Friction is minimized, helping the wheel rotate lightly and move smoothly on many different surfaces. From natural wood floors, carpets to glossy ceramic tile floors. When the user rotates 360 degrees or changes position. The two rows of balls simultaneously distribute the load, helping the chair maintain absolute balance, no vibration, no misalignment. Something that chairs using single ball bearings can hardly achieve.

In addition, the dual ball bearing also provides superior load capacity and high durability. Thanks to the uniform force distribution mechanism, the pressure is not concentrated on a single point. Helps limit wear on the shaft and bearing. The life of the dual ball bearing can be 1.5 to 2 times higher than that of the single type. Ensures the chair maintains stable performance for many years of use. In particular, the dual structure also contributes to reducing vibration and eliminating noise. An extremely important factor in the leadership space, where quietness and sophistication are top priorities.

In terms of design, the double ball bearing allows the creation of chair models that are both flexible and luxurious. Without increasing the size of the wheel. It is a “hidden technology” that helps the chair operate smoothly, durably and contributes to enhancing the value of the interior brand. Showing the class of the classy meeting room space and the position of the person sitting in it. (Balance the conference room chair with tiny adjustable feet).

3. Instructions for storage and maintenance of double ball bearings

Regular cleaning – Maintain smooth movement

Regular cleaning is an important step to maintain the smoothness and longevity of double ball bearings. After a period of use, dirt, hair or small fibers often stick around the wheel shaft. Causing friction and hindering movement. For effective cleaning, use a soft, slightly damp cloth to wipe around the wheel surface. Avoid using strong solvents such as gasoline or industrial alcohol, as they can damage the lubricating grease inside. If you find hair or fibers wrapped around the shaft, use tweezers or a small tool to gently remove them. Do not pull hard, causing the shaft to misalign.

In addition, the chair leg area should be vacuumed periodically to prevent dust from accumulating over time. Proper cleaning not only helps the wheels rotate more smoothly. It also limits ball-bearing jamming, increasing the durability of the entire moving mechanism. This is especially important for high-frequency executive meeting room chairs in luxurious environments.

Lubrication and periodic inspection – Maintain stable performance

After a period of operation, the lubricating grease layer inside the double ball bearing will gradually lose its effectiveness due to friction and temperature. Therefore, experts recommend re-lubricating about every 6 months, with specialized lubricant for precision ball bearings. The process needs to be gentle: remove the wheel from the chair leg. Wipe off the dirt, then drop a few drops of oil into the rotating shaft position. When reassembling, try rotating the wheel so that the oil spreads evenly on the ball surface. During the inspection, if you notice that the wheel has unusual play. Makes a “squealing” or “clacking” sound, it is a sign that the bearing needs to be replaced.

Regular inspections not only help maintain comfort, but also prevent damage from spreading to other parts. A well-maintained dual-ball bearing system will always operate smoothly. Retaining the soft, smooth feel that is characteristic of the chairman’s conference chair – a symbol of tranquility and professionalism.

Ideal operating environment – Factors affecting bearing life

The environment in which the bearings are used plays a key role in the durability of double ball bearings. Ideally, the floor surface should be flat, dry and clean. Avoid exposing the wheels to sand, metal dust or water on a regular basis. Very small hard dust particles can get through the gaps in the dust cover. This can scratch and wear the balls inside.

In addition, the chair should not be subjected to strong impacts such as suddenly pushing the chair against a wall or a hard object. Because that can deform the outer shell or misalign the rotation axis. The room temperature should be maintained at a stable level. Avoid environments that are too humid, because moisture can affect the lubrication ability. Rust the bearings if left for a long time. When used in ideal conditions, the double ball bearings will always operate smoothly. Minimize wear and ensure a long life. Meet the standards of high-class workspaces. Where every detail must reach exquisite perfection.

When to Replace Double Ball Bearings – Signs and Solutions

No matter how durable, dual ball bearings have a certain life limit. Knowing when to replace them is an important factor in maintaining the quality of operation of the chair. If you feel the wheel is no longer moving as smoothly as before. Make a small “squeak” sound or there is a vibration when rotating. This is a signal that the balls inside are worn or unbalanced. When the outer shell is cracked or the wheel shaft becomes loose. The optimal solution is to replace the entire wheel assembly, avoid replacing only a single bearing. Because it can affect the alignment and overall stability.

Replacement should be carried out by a technician or according to the manufacturer’s instructions. To ensure proper installation standards. A new double bearing assembly not only restores the smooth feel. It also helps the chair maintain a luxurious, professional image. This is especially important for conference and executive chairs. Where every movement reflects the style and prestige of the leader. (Wine cabinet in the chairman’s meeting room).
