Office Chair Dual Casters

The commonly used dual casters for office chairs are typically 2-inch universal casters, featuring a threaded rod M10 insert-pin-and-spring structure. They are suitable for executive chairs, swivel chairs, computer chairs, and other scenarios, offering features such as quiet operation and flexible steering. The price range is from 99.00 to 111.00 yuan (minimum order quantity of 1).

Structure and Specifications

The core structure of dual casters is a 2-inch wheel diameter design. The wheel body consists of two wheels side by side, connected to the chair legs via an M10-sized threaded rod insert pin and secured with a spring clip to ensure stable installation and prevent detachment. This design balances load-bearing capacity and flexibility, with each wheel typically capable of bearing over 50 kg, meeting daily office needs. The wheel body is mostly made of high-strength nylon or polyurethane, with a smooth surface that reduces friction noise with the ground, achieving a quiet sliding effect.

Functional Features

1. Universal Steering: Dual casters support 360-degree free rotation, allowing users to move flexibly within the office area without frequently adjusting the chair's direction, enhancing work efficiency.
2. Brake Configuration: Some models offer brake-equipped options, allowing users to lock the casters via foot pedals or manual operation to prevent accidental chair movement and enhance safety.
3. Quiet Design: The contact surface between the wheel body and the ground is made of soft materials, combined with precision bearings, effectively reducing friction noise during sliding, suitable for offices or meeting rooms requiring a quiet environment.

Suitable Scenarios and Prices

Dual casters are widely used in office furniture such as executive chairs, swivel chairs, and computer chairs, especially suitable for hard floors (e.g., tiles, wooden floors). Their prices are influenced by factors such as material and brake function. Basic models without brakes cost approximately 99.00 yuan each, while models with brakes or high-end materials can reach 111.00 yuan each, with possible discounts for bulk purchases.

Purchase Recommendations

1. Confirm Chair Leg Specifications: Before purchasing, measure the diameter of the chair leg's insert hole to ensure it matches the M10 threaded rod of the casters.
2. Floor Type: If the floor is carpeted, it is recommended to choose a model with a slightly larger wheel diameter (e.g., 2.5 inches) to enhance maneuverability.
3. Brake Requirements: Decide whether a brake function is needed based on the usage scenario. For example, workstations requiring chair immobilization can prioritize brake-equipped models.
