The type of use intended for your equipment will determine the selection criteria of your wheel and castor. For example, do you need the wheel to swivel or roll straight or how the castor will be fitted to the top-plate.
The size and density of the wheel is dependent on the weight of the load. To calculate the weight distribution, divide the gross weight (the weight of the transport unit plus the weight of the load) by the number of wheels/castors attached. This can be determined by the following equation.
The starting, rolling and swivel resistance relies on choosing the right type of tread, bearing and wheel to the load weight and surface conditions.
Operational comfort is determined by selecting the correct shape and tread material of the wheel.
A rule of thumb is that the tread should be softer than the floor material. This will eliminate damage to the floor.
The type of wheel bearing depends on the load size, speed, environmental influences and the amount of starting force required.
|Plain Bore||Rugged, resistant to humidity, high start, and rolling resistance|
|Roller bearings||Rugged, have low rolling resistance and low radial bearing clearance|
|Ball Bearings||Quickest starting and rolling, lowest bearing clearance, high load capacity and suitable for higher speeds|
The product lifespan and functionality depends on selecting the correct wheel for the situation. This minimises the risk of corrosion due to extreme temperatures and chemical substances.
