Selection of universal wheel structure
1. Steering structure
Ordinary universal wheel: 360 ° free rotation, flexible movement, suitable for daily use
Directional wheel (straight wheel): can only travel in a straight line, usually used in combination with universal wheels (such as 20000+2 fixed wheels for carts) to improve straight stability
Universal+directional switching wheel: with locking structure, can switch between rotation/straight travel, commonly used in high-end carts and medical equipment
2. Braking function (must see, strongly recommended for home use with brake)
No brakes: only suitable for fixed position, rarely moving furniture, easy to slide and shift
Universal brake (full brake): lock the wheel rotation and bracket steering at the same time, fix firmly, prioritize
Wheel surface brake (single brake): only locks the wheels to roll, the bracket can still rotate, and the fixing effect is average
Foot brake: Operated with feet, no need to bend over, practical for carts, office chairs, and large furniture.
