Traditional Office Chair Casters

Traditional office chair casters are wheel-type accessories primarily made of rubber and other materials, featuring diverse specifications and functions tailored to office environments. They are quiet, wear-resistant, and easy to install, with prices varying significantly based on configuration differences.

Materials and Specifications

The most common material for traditional office chair casters is rubber, with some products incorporating nylon or metal-reinforced structures to enhance durability. In terms of specifications, 2 inches is the mainstream size, compatible with the wheel-axle interfaces of most office chairs. Customization options are also available for different sizes (e.g., 1.5 inches, 2.5 inches) and material combinations to meet special requirements. For example, some high-end products feature soft rubber-wrapped metal wheel cores, balancing quiet operation and load-bearing capacity.

Installation Methods

The design of caster installation prioritizes convenience and mainly falls into two categories:

1. Threaded Insertion Type: These casters are directly screwed into the chair-leg mounting holes using threads on the wheel axles (e.g., M10 specification). They offer secure installation and easy removal, suitable for most metal or plastic chair legs.
2. Snap-Ring Insertion Type: The wheel axles are designed with snap-ring structures at their ends, which are inserted into the chair legs and secured with elastic clips. These casters can be quickly replaced without tools and are commonly found on lightweight office chairs or in temporary-use scenarios.

Functional Characteristics

The functional design focuses on meeting the demands of office environments:

• Quiet and Wear-Resistant: The rubber wheel bodies reduce friction noise with the floor while resisting daily wear, extending service life.
• Brake Function: Some threaded casters are equipped with brake mechanisms that lock the wheel position by rotating the wheel body, preventing the chair from sliding on slopes or smooth surfaces and enhancing safety.
• Load-Bearing Adaptation: The wheel structure is adjusted according to the type of office chair (e.g., executive chairs, swivel chairs) to ensure that each caster can bear loads of over 50 kg, avoiding deformation or jamming.

Price Range

The price of a single caster varies widely, ranging from 0.51 yuan to 111 yuan, influenced by factors such as:

• Material: Basic rubber models are priced lower, while metal or composite material models are more expensive.
• Function: Additional features like brakes or anti-tangling mechanisms increase costs.
• Bulk Purchasing: Wholesale prices are typically 20%-50% lower than retail prices, making them suitable for enterprises or maintenance providers.

Application Scenarios and Maintenance

Casters are widely used in office furniture such as executive chairs, swivel chairs, and computer chairs. Some products can also be compatible with home environments like wooden floors or carpets by adjusting wheel hardness or size. Daily maintenance requires attention to cleanliness to prevent hair or dirt from causing poor rotation. This can be achieved by wrapping a damp facial towel around the wheels and moving the chair to wipe them or using low-tack tape to prevent dirt adhesion.
