Caster wheel prices range from tens to thousands of baht per wheel. The difference isn't random — it comes from the materials and quality inside. This article summarises what makes prices differ, so you pay only for what you need and get good value.
Factors That Affect Price
- Tread material: high-quality PU costs more than ordinary rubber or plastic, but lasts longer and leaves no marks
- Steel core thickness: a thick cast core (5.5 mm) costs more than a thin pressed core, but genuinely carries the load
- Wheel size: 6 inch uses more material than 4 inch, so it costs more
- Bearings: sealed double bearings cost more than a plain bush, but push more smoothly and last longer
- Caster type: brake > swivel > rigid, as the mechanism becomes more complex

Don't just look at the lowest price: cheap wheels that fail quickly must be replaced often, plus the cost of floor repairs and work stoppages — in total it costs more than buying quality from the start
Summary
Choose wheels by "cost per service life", not just the sticker price. Cast-iron-core PU wheels usually give better value for factory work with heavy daily use.
