Office Chair Dual-Wheel Casters
The 2-inch dual-wheel threaded-rod insert snap-ring type office chair caster is a universal heavy-duty silent caster suitable for executive chairs and computer chairs. It features a stable structure, durable material, and flexible rotation. The price ranges from 99.00 yuan to 111.00 yuan, with a minimum order quantity of 1.
I. Structure and Compatibility
This caster adopts a threaded-rod insert snap-ring design, secured to the chair legs with a snap ring for easy installation and strong stability. Its 2-inch size (approximately 50.8 millimeters) is a common office chair caster size, compatible with the leg hole diameters of most executive chairs and computer chairs. The threaded-rod structure ensures a tight connection between the caster and the chair legs, preventing loosening or detachment during use, making it suitable for office scenarios requiring frequent movement.
II. Material and Durability
The caster's bracket is made of 2mm thick steel plate, which forms a dense oxide layer on the surface after chrome plating, effectively preventing rust and corrosion and extending its service life. The wheel body is made of rubber, which is elastic and wear-resistant, reducing scratches on the floor and lowering noise during movement. The combination of rubber and steel plate balances flexibility and support, making it suitable for carrying heavy loads.
III. Rotation Performance
The caster has a single built-in bearing, and precise machining ensures a reasonable gap between the rotating shaft and the bearing, enabling 360-degree flexible rotation. The caster design allows the chair to move easily in any direction, enhancing usability. The lubrication treatment of the bearing further reduces friction, ensuring smooth rotation even after long-term use and preventing jamming or abnormal noises.
IV. Silence and Load-Bearing Capacity
The rubber wheel body effectively absorbs vibrations during movement, and combined with the low-friction design of the bearing, the operating noise is extremely low, making it suitable for offices or meeting rooms requiring a quiet environment. As a heavy-duty caster, its structural strength can bear high weights, meeting the usage needs of executive chairs and other heavy-duty seats, preventing deformation or damage to the caster due to overloading.
V. Price and Purchase
The unit price of this caster ranges from 99.00 yuan to 111.00 yuan, with a minimum order quantity of only 1, making it suitable for individual users for replacement or small-batch purchases. Price differences may stem from material details (such as rubber hardness, chrome plating process) or sales channels. It is recommended to choose cost-effective products based on actual needs.
