GUIDE TO CHOOSING WHEELS

A wheel is a circular object that can rotate around a central axis.

The wheel is composed of the following elements:
1. core
2. coating
3. hub
4. support

Wheels can be made of different materials both for the core and for the coating. They also differ in size, type of sliding and load capacity. For each individual need it is essential to identify the most suitable wheel, with any support.
In this choice it is necessary to take into account the type of use, the environment of use and the load it will have to support.

THE SUPPORT
The support is a connecting element between the wheel and the trolley/machinery/equipment etc. Manually operated wheels are usually not drive wheels but are only intended for towing or pushing operations with manual or mechanical means at reduced speed (max 4 km/h).

There are different types of support depending on the type of rotation and movement that allow:

Rotating supports
Rotating supports rotate around their vertical axis as the direction of travel changes. They can be with a plate, with a through hole, with a smooth pin or threaded pin. All these types of supports can have a built-in brake.

Fixed supports
It cannot rotate, it serves to keep the wheel along a guide line and is only available in the plate version.

On the same trolley/machinery/equipment it is possible to use wheels with different supports to maximize its performance.

TYPES OF SCROLLING

	Bushing bore: The bushing is the simplest, cheapest and most resistant type of sliding. Wheels with supports and through hole are normally used for trolleys moved at low speed and short distances. This type of sliding does not require particular maintenance except in some cases where the use of grease and oil is recommended. It is particularly resistant to corrosion and impacts.
	Needle Roller Cage: The needle roller cage bearing is a strong slide with a small assembly space that does not require any particular maintenance. It is the most used type of slide for light-medium loads. It consists of steel rollers caged in a steel or nylon structure. The rollers are lubricated at the time of assembly so they do not require any further maintenance.
	Ball Bearing: The ball bearing is ideal for medium-heavy loads where ease of sliding is of primary importance. It is composed of steel balls inserted in a cage that rotates between an outer ring and an inner ring also made of steel. The balls are lubricated at the time of assembly and sealed for better waterproofing.

TYPES OF SUPPORTS

For wheels with fixed and rotating supports, it is necessary to securely fasten the wheel to the trolley/equipment/machinery.

The fixing elements present in our wheels are the following:

Plate fixing

to screw, it is recommended for all machinery or flat surfaces. They are used for both light loads and high capacities usually for industrial applications.
Particular attention must be paid to the dimensions of the plate, the fixing hole spacing as well as the diameter of the fixing holes.

Fixing with central hole

This type of fixing has a central hole to screw onto the trolley.
Particular attention must be paid to the diameter of the plate and the diameter of the central hole.

Fixing with threaded shank

The shank is screwed directly into the carriage and secured with a nut. Pay attention to the diameter of the threaded shank and the length of the shank.

Fixing with smooth shank

the shank is fixed directly into a tube or hole. It is used in the case of light-duty wheels.
There is also a version with a clip-on shank: the shank is inserted into a special tube and secured with a spring ring.
Wheels with this type of fixing are quick to mount and are usually used for furniture wheels.
When choosing a shank fastening, the shank diameter and length must be considered.
