What factors influence the swivel resistance?
The swivel resistance of castors and wheels influences the manoeuvrability of a device.
One type of resistance to which wheels and castors are subjected is the swivel resistance. This is the force that has to be applied to keep the rolling equipment in motion and to manoeuvre it. A distinction must be made between this swivel resistance and the starting resistance. The latter describes the force required to set a device in motion from a stationary position.
Factors influencing the swivel resistance
The swivel resistance depends on various factors. These include the tread and the hardness of the tread as well as the offset. The floor conditions are also important. The basic principle here is: soft floor = hard castors and vice versa. In addition, influences such as the type of swivel bearing, the ball race diameter and the load that the castors must withstand must be taken into account.
And the number, type and arrangement of the castors are also relevant when it comes to manoeuvrability. If, for example, only fixed castors are attached to a device, it will be difficult to turn, but will travel very well in a straight line. If fixed and swivel castors are combined, or swivel castors with a directional lock are used, the device can be steered in all directions without any problems. The type and combination of castors selected therefore depends on the function of the equipment. If the equipment often has to be turned and steered in different directions, swivel castors are indispensable. If, on the other hand, the equipment is mostly moved in a straight line, fixed castors offer a more stable ride.
