Enhanced Durability, Reduced Noise, and Reliable Performance
SMOOVE TURN BASE is an innovative rotating mechanism designed to deliver smooth operation without the use of bearings, leveraging advanced friction control technology. This cost-effective, compact, and streamlined design addresses the common issue of noisy ball bearing systems while achieving exceptional durability and performance. The rotation is precisely calibrated to provide a premium, tactile experience—neither too light nor too heavy. Additionally, an optional stopper function allows the rotation to be securely fixed at any desired position, ensuring safety and ease of use for children and the elderly, particularly during standing or sitting movements.

SMOOVE TURN BASE is engineered to be thinner than traditional ball bearing turntables, allowing seamless integration without compromising the chair’s design integrity. Its high degree of design flexibility accommodates custom requirements, so please feel free to contact us to discuss tailored solutions.

Core Technology: Advanced Friction Control
Unlike traditional ball bearing turntables, which may produce metal debris due to wear, leak lubricating oil, or require repair/replacement, the SMOOVE TURN BASE eliminates these concerns. Issues such as ball dislodgement under excessive loads are also mitigated. With its exceptional durability, this technology has been adopted by leading furniture manufacturers for approximately five years with zero complaints, allowing us to recommend it with utmost confidence.
The Secret to Smooth Rotation
The SMOOVE Friction Device employs a highly wear-resistant material sandwiched between metal plates, with meticulously adjusted tension to achieve a perfectly balanced, tactile rotation. This proprietary friction control technology is the key to its enduring acclaim among customers. Additionally, as it operates without oil, there is no risk of lubricant leakage.

Rigorous Durability Testing
Test Method 1: A 60 kg weight was placed approximately 50 mm off-center on the chair’s seat surface and rotated between 50° and 70° for 100,000 cycles. Test Results: 1: Rotational resistance remained consistent with initial settings, with no unintended inertial movement. 2: No significant wear was observed on the resin sliding components. 3: The seat exhibited minimal wobbling, and the test was completed successfully. |
Test method 2: An 80 kg weight was placed at the center of the chair’s seat surface, with a stopper applied to prevent rearward movement of the back legs. The front legs were lifted approximately 100 mm by pushing the seat backward and returning it, repeated for 30,000 cycles. Test results: No changes in appearance or occurrences of wobbling were observed. |
Comparison with Bearing-Type Mechanisms
Bearing-type mechanisms suffer from repeated wear, leading to the generation of black debris that contaminates grease. Additionally, increased clearance over time results in wobbling. In contrast, the SMOOVE TURN BASE maintains stability and cleanliness, showcasing superior durability and performance.

Technical Application Idea
Effortless Rotation for Heavy Loads
It is capable of 360° rotation and can stop at any angle, making it ideal for use in logistics environments.

Contribution to Lightweight Trains and Improved Fuel Efficiency
Unlike conventional seat adjustment methods that require significant effort to lift and reposition, the SMOOVE TURN BASE’s rotation mechanism enables effortless operation, making it accessible for individuals with limited strength. Furthermore, the lightweight design of its components contributes to overall train weight reduction, potentially enhancing fuel efficiency.
