1. Which Material Has Stronger Load Capacity?
Cast iron, iron core, and injection molding can all bear 120kgs of dynamic load. The main differences are cost and weight:
- Cast iron is the cheapest and heaviest.
- Iron core + polyurethane is mid-priced and easier to push.
- Full injection molding with fiberglass is lightweight and low cost, sufficient for home use.
2. What makes the bracket colorful?
- Silver: electroplated with a layer of zinc, rust-resistant for 48 hours in salt spray.
- Black: sprayed with black paint, rust-resistant for 24 hours in salt spray, looks good but not suitable for bathrooms.
3. How to Choose Bearings?
- Single bearing: high speed, cheap, suitable for occasional movement.
- Double bearing: stable, quiet, expensive, suitable for daily pushing scenarios.
- Triple bearings currently have low cost-performance and can be ignored.
4. Which Brake Is Better?
- Side brake: foot presses the side, highly compatible.
- Double brake: foot presses the top, leave 5 mm height when installing, otherwise it can’t be pressed.
In Summary, measure the inches well, calculate the load capacity, check the rust resistance time, then decide whether to spend extra for quietness.
