Crossbar Office Chair Wheels

Currently, no specific price or detailed description information directly related to 'crossbar office chair wheels' has been found, but relevant caster types and purchasing suggestions are provided for reference.

Common Types of Office Chair Casters

1. Wheels with Brake Lock Function These wheels are fixed by built-in brake devices and are suitable for scenarios requiring stable support (such as drawing and precision operations). The brake mechanisms are usually foot-operated or manually pressed, and the materials are mostly nylon or polyurethane, which have strong wear resistance. However, prices vary greatly depending on the brand, with ordinary models costing about 20-50 yuan each and high-end models possibly exceeding 100 yuan.

2. Gravity Wheels Gravity wheels trigger the locking mechanism through body weight. They automatically fix when sitting down and unlock for movement when standing up. Their core components are springs or hydraulic devices, making them suitable for scenarios that require frequent switching between mobile and fixed states (such as conference rooms and training rooms). The price range is wide, with basic models costing about 30-80 yuan each and imported brands possibly reaching over 150 yuan.

3. Fixed Foot Pads Fixed foot pads are designed without wheels and provide anti-slip support through rubber or plastic materials. They are suitable for hard floors (such as wooden floors and tiles) or scenarios requiring complete stillness (such as medical chairs and laboratory chairs). The prices are relatively low, usually 5-20 yuan each, but it is necessary to ensure they match the size of the chair feet.

4. Bearing Hollow Wheels Bearing hollow wheels adopt a hollow design to reduce weight and are equipped with ball bearings inside to reduce friction. They are suitable for scenarios requiring high-frequency movement (such as gaming chairs and office swivel chairs). The materials are mostly nylon or metal, with prices around 15-40 yuan each. High-end models may use silent bearings, doubling the price.

Purchasing Suggestions

• Size Matching: The wheel diameters are usually 50mm or 65mm. Choose according to the hole diameter of the chair feet to avoid installation difficulties or looseness.
• Material Selection: Polyurethane wheels are suitable for carpets, and nylon wheels are suitable for hard floors; metal wheels are wear-resistant but may scratch the floor and need to be used with foot pads.
• Functional Requirements: If frequent movement is required, prioritize bearing wheels; if fixation is required, brake wheels or fixed foot pads can be used in combination.
• Customization Services: Some manufacturers support customization of size, material, and color, but the minimum order quantity is relatively high (usually over 50 pieces), suitable for bulk purchases.
