How to select the proper castor wheel?

The load capacity given one based on maximum value under ideal conditions of use with progressive speed(max 4km/h) on flat surfaces. The minimum load capacity per castor is calculated as the sum of the weight of the carrier plus the maximum added load divided by 3.

Load Capacity = (Weight of Carrier + Additional Load) / 3

However, if the castors are to be subjected to unusual shock or impact or uneven floors, then the next greater castor capacity is advised.

Wheel Material :
For applications include exposure to oils, grease, acid solution and other unusual environmental conditions.

Wheel Hardness :
Hard tread wheels normally require less starting force, advantages are higher load capacity. Soft wheels roll easier over obstruction, provide better floor protection, shock absorption and traction.

Wheel Diameter :
Large wheel roll easier, is more maneuverable, can overcome obstruction and floor ruts easier than smaller diameter wheel.

Plate fitting :
Plate type fitting normally mounted on flat surface.

Bolt Hole Fitting :
Hollow attachment allowing fitting by bolt and nut.

Stem fitting :
Solid or threaded for fitting into tubes.

Ball Bearing :
Low noise, meets highest demands of load capacity, especially suitable for heavy duty castors.

Roller Bearing :
Robust and maintenance free, rolling resistance low even with heaviest load.

Plain Bearing :
Value for money, suitable for outdoor usage.

Flange Bearing :
Light running bearing, low noise especially suitable for apparatus castors.
