Basic concepts
A brief guide to terminology related to wheels and wheelsets.
Start with the basics
Wheel
A wheel is a mechanical component that enables rotational movement and is a key part of any wheelset. It includes the part that makes contact with the surface and often internal elements, such as bearings.
Tread
The tread is the part of the tire that directly contacts the surface. Its design and material are essential for the wheel's driving characteristics, such as grip, rolling resistance, and ride comfort. The tread can have various patterns and textures tailored to specific conditions, such as rough surfaces or environments with high contamination levels.
Hub
The central part of the wheel, where the bearings are mounted, and which connects the wheel to the axle or mounting.
Tire
The tire is a flexible component mounted on the wheel's edge, providing better grip and cushioning. Tires can be made from various materials such as rubber, polyurethane, or Vulkollan. Depending on the material, tires may offer properties like wear resistance, vibration dampening, or surface protection.
Wheelset
A wheelset is a complete assembly consisting of a wheel and additional components, such as axles, mounts, or swivel mechanisms. Wheelsets can be fixed, swivel, or combined, depending on the application requirements.
Bearing
A bearing is a mechanical element that enables smooth rotational movement between different machine parts. It is mounted inside the wheel or wheelset and is responsible for reducing friction and supporting the axle. There are various types of bearings, such as ball, roller, and plain bearings, each with different properties and applications.
Mounting plate
A metal plate to which the wheel is attached, and which is mounted to the base of the device.
Screws and nuts
Fastening elements used to attach the plate to the device.
This guide aims to facilitate understanding of the basic terminology related to wheels and wheelsets, helping to tailor product selection to individual needs.
