How to select a suitable caster


There are three types of caster: swivel, brake and rigid. Swivel caster can rotate to 360 degree freely. Brake caster can stop the wheel with a stepper. And rigid caster just can go straightly, it can’t rotate. The followings as below are five tips to select a suitable caster.


Load Capacity:

The load capacity is the maximum weight that each caster can support individually. The heavier the load, the larger the wheel required for the caster. The weight of the load also influences the mobility of the wheel. Hence, in order to select the suitable caster, please measure the required load capacity. Load Capacity = Weight of Product or Estimated Load ÷ Required number of Casters


Wheel Size:

There are lots of wheel size, and HO CASTER provide 2-8 inch caster wheel. In normal, there are two size units: inch and mm. 1 inch = 25.4 mm. And wheel size = Wheel Diameter x Wheel Width.


Overall Height:

Measured from the floor to the actual mounting point is the required overall height.


Floor Conditions:

Floor Conditions affect the performance of mobility of caster and wheel. For example, rugged floor is suitable for elastic rubber wheels; the PU wheel has the better performance on the floor with oil or chemical. For more information about wheels performance on different flooring type, please navigate to our wheel type page.
