Office Chair Snap-Ring Brake
Product information related to office chair snap-ring brakes is as follows:

I. Snap-ring casters with braking function
The 2-inch snap-ring braking casters for swivel office chairs are common braking components for office chairs. Their core function is to fix and release the wheels through the snap-ring structure. These casters usually adopt a universal wheel design, with a diameter of 2 inches (approximately 50.8 millimeters), and are compatible with M10 threaded rods. They can be directly inserted into the reserved holes in the base of the office chair. The braking mechanism is achieved through the elastic deformation of the snap-ring: when it is necessary to fix the position of the chair, step on the brake pedal, and the snap-ring will squeeze the brake pad inside the wheel, creating friction with the wheel hub to generate resistance and stop the rolling; after releasing the brake, the snap-ring returns to its original shape, and the wheel resumes free rotation. These casters are relatively inexpensive, with a unit price of approximately 1.14 yuan, making them suitable for cost-sensitive bulk procurement scenarios.
II. Snap-ring fixed casters without braking function
If the office chair does not need to be moved frequently, snap-ring fixed casters without braking function can be selected. These casters are firmly installed through a snap-ring insertion design, with a common diameter of 2 inches and compatibility with M10 threaded rods. Their structures are divided into two types:
- Basic anti-slip type: The bottom of the caster is equipped with rubber or felt pads to prevent the chair from sliding by increasing friction. The price is approximately 1.71 yuan per caster, suitable for hard floors (such as tiles and wooden floors).
- Reinforced solid type: It adopts a solid wheel body made of PVC or metal, with stronger load-bearing capacity. The price is approximately 2.0 yuan per caster, suitable for scenarios where users have a relatively large body weight or need to frequently move heavy objects.
III. Key points for selecting snap-ring braking components
- Compatibility: It is necessary to confirm that the threaded rod specification of the caster (such as M10) matches the insertion hole in the base of the office chair to avoid installation difficulties.
- Brake sensitivity: For casters with braking function, test the pedal travel of the brake to ensure quick braking after stepping on it and avoid slipping.
- Silence: Prioritize wheel bodies made of rubber or PVC materials, which can reduce friction noise with the ground and enhance the user experience.
- Load-bearing capacity: Select the wheel body material according to the user's body weight. Solid wheel bodies are more pressure-resistant than hollow wheel bodies and are suitable for long-term use.
IV. Maintenance suggestions
Regularly check the elasticity of the snap-ring of the snap-ring braking casters. If there is looseness or deformation, replace it in a timely manner to avoid brake failure. In addition, if the surface of the wheel body is stained with dust or hair, it can be cleaned with a damp cloth to prevent affecting the smooth rotation.
