Office Chair Base Casters

There are various types of office chair base casters with significant price differences, and specific screws and washers are required for installation.

I. Types and Prices of Office Chair Base Casters The material and design of office chair base casters directly affect their performance and price. Common types include:

1. Silent Rubber Casters: Such as "Silent Office Chair Universal Casters Swivel Chair Wheels", priced at approximately ¥13.0. These casters are made of rubber material, effectively reducing noise during movement, suitable for office environments with high noise reduction requirements.
2. High-Load PU Casters: Such as "Black Transparent Swivel Chair Wheels Universal Wheels Gaming Chair Office Chair Casters", priced at approximately ¥8.12. PU material is wear-resistant and impact-resistant, and the dual-bearing design further enhances the smoothness of sliding, suitable for gaming chairs or high-frequency use scenarios.
3. Universal TPR Casters: Such as "2-inch/2.5-inch TPR Silent Wheels Office Chair Universal Wheels", priced at approximately ¥8.5. TPR material combines the advantages of rubber and plastic, offering both elasticity and durability, and is a cost-effective choice at a moderate price.
4. Economy Plastic Casters: Such as "Universal Swivel Chair Wheels Office Chair Computer Chair Silent Casters", priced as low as ¥1.24. These casters are primarily made of plastic, with lower costs, but relatively weaker load-bearing capacity and durability, suitable for lightweight office chairs or temporary use.
5. Fixed PVC Glides: Such as "Reinforced Solid Version Swivel Chair Fixed Casters", priced at approximately ¥1.71. Unlike universal wheels, fixed glides use a snap-in design to position the chair, suitable for scenarios requiring stability (such as conference chairs).

II. Installation Precautions Taking the 2022A office chair as an example, the following steps should be followed when installing base casters:

1. Tool Preparation: Screws J and K, as well as washer L, are required. The screw specifications should match the caster hole positions, and the washer is used to distribute pressure and prevent chassis deformation.
2. Installation Sequence: First, insert washer L onto screw J, then pass it through the chassis hole position, and finally secure the caster with screw K. Ensure that the screws are tightened to prevent looseness, but avoid excessive force that may impede caster rotation.
3. Compatibility Check: Some casters need to be confirmed for compatibility with the chair base's snap rings or hole distances, for example, 2-inch/2.5-inch TPR casters require specific-sized slots.

III. Purchase Recommendations Choose caster types based on usage scenarios: For high-frequency movement scenarios, prioritize PU or rubber casters; for limited budgets and low usage frequency, plastic casters can be selected; for chair fixation, choose PVC glides. Before installation, be sure to check the screw specifications and chassis compatibility to avoid rework due to mismatched accessories.
