Office Chair Foot Nails and Casters

Office chair foot nails and casters come in various types, with prices varying based on specifications and functions. The following provides a detailed explanation from the perspectives of types and prices:

I. Types

1. Fixed Foot Nails and Universal Casters
   Fixed foot nails are typically used in scenarios requiring stable support, such as the fixed foot nails of anti-static office chairs. Their design achieves secure installation through a snap-ring structure, preventing sliding. Universal casters, on the other hand, support multi-directional rotation and are suitable for scenarios requiring flexible movement, such as swivel chairs and work chairs. Some products combine the characteristics of both, for example, the "straight-insert threaded fixed wheel" is fixed through a threaded structure while also having basic sliding functionality.
2. Materials and Structures
   In terms of materials, nylon and metal are common. Nylon wheels are lightweight and wear-resistant, suitable for light furniture; metal wheels have stronger load-bearing capacity and are suitable for heavy equipment. Structurally, snap-ring types are fixed through elastic snaps, straight-insert types rely on threads or insert rods for connection, and snap-button types achieve quick disassembly and assembly through plastic snap buttons.
3. Functional Extensions
   Some foot nails and casters integrate features such as anti-static, quiet operation, and wear resistance. For example, anti-static casters release static electricity through conductive materials and are suitable for electronic workshops; quiet wheels use special materials or shock-absorbing designs to reduce movement noise.

II. Prices

1. Economy Type (¥0.75 - ¥1.43)
   These focus on basic functions. For example, the "Rose 10x15 Nylon Solid Fixed Wheel" is priced at ¥0.75 and is suitable for light furniture sensitive to cost; the "Swivel Chair Accessory Fixed Foot Caster" is priced at ¥1.43 and features a straight-insert threaded design, being simple and practical.
2. Mid-range Type (¥2.38 - ¥3.6)
   These balance functionality and durability. For example, the "Anti-static Fixed Caster" is priced at ¥2.38 and is suitable for scenarios sensitive to static electricity; the "Universal Caster Snap-ring Caster" is priced at ¥3.6 and supports 2-inch snap installation, being suitable for work chairs or stools.
3. Factors Affecting Price Differences
   Materials, sizes, and functions are the main influencing factors. Metal wheels are generally more expensive than nylon wheels; large-sized wheels (such as 2-inch ones) are more expensive than small-sized ones due to their stronger load-bearing capacity; additional functions such as anti-static and quiet operation increase costs.

Summary: The selection of office chair foot nails and casters should be comprehensively considered based on the usage scenario, load-bearing requirements, and budget. Fixed foot nails are suitable for stable scenarios, while universal casters are suitable for flexible movement; nylon wheels are lightweight and economical, while metal wheels are durable but have higher costs; additional functions such as anti-static and quiet operation should be configured as needed.
