💡 Why do shops prefer roller bearing casters for heavy utility platforms over basic sleeve types?
- Standard sliding pins wear out quickly under stress while sealed designs keep plates spinning freely

- It keeps polished concrete intact since the wheels track straight without dragging sideways
- You just drop them into existing holes and they clear stubborn jam spots fast
