Office Chair Metal Wheels

Office chair metal wheels come in a variety of types, with differences in specifications, functions, and applicable scenarios. Selection should be based on specific needs.

1. Common Types and Specifications
Office chair metal wheels are differentiated by size and structure, with common specifications including 1.5-inch and 2-inch options. For example, the 2-inch insert-rod carpet swivel chair wheels feature a spherical design, suitable for soft surfaces like carpets. They reduce pressure by increasing the contact area, preventing the wheels from sinking in. The 1.5-inch snap-ring zinc alloy PP casters are fixed with a snap-ring structure, making installation easy and suitable for hard floors. Additionally, some wheels adopt a dual-wheel design (such as cross-border zinc alloy casters), enhancing stability by distributing pressure, ideal for heavy-duty scenarios.

2. Material and Durability
The core material of metal wheels is zinc alloy, known for its high strength and corrosion resistance. Compared to plastic wheels, they are more wear-resistant and have stronger load-bearing capacity. For instance, the 2-inch zinc alloy casters (TFE0101) directly sold by Tefer Factory are optimized with an alloy formula, capable of bearing dynamic loads over 50kg, suitable for long-term use. Some wheel shells are made of PP (polypropylene) material, reducing weight and minimizing friction noise with the ground.

3. Functional Features

• Brake Locking: Some wheels are equipped with brake devices (such as cross-border 1.5/2-inch zinc alloy casters), enabling fixation through foot pedals or manual switches, suitable for scenarios requiring stable positioning (such as drawing or meetings).
• Silent Design: The wheel surfaces are wrapped with PU (polyurethane) or rubber layers, reducing friction noise with the ground, ideal for quiet environments like offices and libraries.
• Omnidirectional Rotation: All metal wheels support 360-degree rotation, enhancing chair flexibility. However, rotation resistance varies by design (e.g., spherical wheels rotate more smoothly).

4. Applicable Scenarios and Selection Advice

• Carpet Floors: Prioritize 2-inch large-diameter wheels to avoid sinking into fibers; for thicker carpets, choose models with hard rollers.
• Hard Floors (Wooden Floors, Tiles): 1.5-inch wheels are sufficient, but pay attention to silent performance to avoid scratching the floor.
• Heavy-Duty Needs: Select wheels with a dual-wheel structure or thickened zinc alloy brackets to ensure load-bearing safety.
• Budget Considerations: Basic zinc alloy wheels cost about 10-20 yuan each, with prices for models with brakes or silent features increasing by 30%-50%.

5. Maintenance and Precautions
Regularly clean hair and dust from the wheel gaps to prevent jamming; if the wheels do not rotate smoothly, add a small amount of lubricant (such as WD-40); avoid long-term use in humid environments to prevent metal rusting.
