How To Select Right Castor Wheel
The following factors must be considered when selecting the right castor wheel for your application. Many factors together contribute in making a decision to select the most suitable castor wheel.
Depending on the type of application, swivel, fix or brake type castors can be used. One should also look at the installation fitting required for the castor. The castors come with top plate, thread pin, stem and bolt hole fittings.
The size of the wheel increases with the load. The possibility of overload, shock load and poor floor conditions require a safety factory to be included in the formula. The formula below enables load calculation over each castor wheel , considering some of the most important factors.
The formula below enables load calculation over each caster or wheel, considering some of the most important factors.
C = PE + PMC * S
C = Load per caster or wheel (kg),
Pe = Equipment, cart or structure weight (kg),
Pmc = Maximum load weight to be carried (kg),
N = Number of casters or wheels,
S = Safety coefficient
Do you need the floor to be protected or require noiseless movement? Do you have mixed use on asphalt and epoxy flooring? Decide on these conditions and then chose the right wheel material for your application.
Extreme conditions such as high temperatures, oil & chemicals, heavy washing of the equipment, germ free environmentetcmust be factored in when choosing the castor wheel.
The swivel head bearings and the wheel center bearings play an important role to make a decision whether the loads are to be pushed manually or being pulled by a towing truck. Select the right bearing considering the load speed and the amount of force needed to bring the loaded equipment in motion.
