Caster wheels step into our life

About casters

Sometimes , the most simple inventions are significant . Even though we have no idea about who is the one invent caster wheel , however , the record of casters can be dated from 5500 years ago . People must to push goods very tough and hard before has wheels . One day , people were enlightened by the slick stone rolled from top to the foot of the hill , therefore we have an idea to invent caster wheels.

Caster created revolution that people don't have to carry one goods to another goods by hand . We have bicycles , cars , trains and trolleybus is just because the involution of the caster wheels .

Caster wheel is widely used in many areas , there is no doubt that we all need it . According to the development of the caster , it has 150,000 different types at least caster we are using at present . It indeed created a more convenient , efficient and safe labor life for every one of us .

The basic type of caster

1. Swivel Caster: The wheel is mounted on a pedestal with eccentric distance, and the bracket is free to rotate around the vertical axis of lead.

2. Rigid Caster: The wheel is mounted on a bracket that cannot be turned.

3. Single brake: A single brake device with a stop wheel.

4. Double brake: A dual braking device that can stop wheels turning and turning wheel.

The parameter of the caster

1. Wheel diameter: Wheel diameter nominal size.

2. Wheel width: The maximum width of a wheel parallel to the axis of rotation.

3. Tyre width: The width of a tire that is parallel to the axis of rotation.

4. Mount height: The caster is fitted with a vertical plane to the ground.

5. Radius of rotation: The steering shaft of the caster is the horizontal distance from the most prominent point of the caster.

6. Walking speed: within 4km/h

How to stock casters?

The storage warehouse shall be well ventilated, with relative humidity less than 80%, no corrosive gas inside, and the storage period shall not exceed 24 months.

Casters and wheels are essential components for mobility in various applications, but they are not the same.

A caster consists of the rig (the part that holds the wheel) and the wheel. It mounts to the bottom of a larger object, such as a cart or dolly, so operators can easily move the object. Casters come in different materials, wheel diameters, tread widths, load ratings, and overall heights to give your equipment mobility in many kinds of work environments.

Here's a detailed explanation of each and their differences:

Casters

Definition: Casters are assemblies that include a wheel and a mounting system. They are designed to be attached to the bottom of an object, allowing it to move easily.

Components:

1. Wheel: The rotating part that makes contact with the ground.
2. Mounting System: This can be a plate or a stem that attaches the wheel to the object. The mounting system often includes a swivel mechanism.

Types of Casters:

1. Rigid (or Fixed) Casters: These only allow back-and-forth movement. They do not swivel, making them suitable for straight-line travel.
2. Swivel Casters: These can rotate 360 degrees, allowing for more maneuverability. They are often used in combination with rigid casters for easier directional control.

Applications: Casters are used in furniture, industrial equipment, medical equipment, office chairs, carts, and many other items that require mobility.

Wheels

Definition: Wheels are simple circular components that rotate around an axle. They are one part of a caster but can also be used independently.

Components:

1. Wheel: The round part that rolls on the ground.
2. Axle: A rod or spindle that passes through the center of the wheel, allowing it to rotate.

Types of Wheels:

1. Solid Wheels: Made from a single piece of material, providing durability and strength.
2. Spoked Wheels: Have spokes between the hub and the rim, often lighter and used in applications like bicycles.
3. Pneumatic Wheels: Filled with air, providing cushioning and shock absorption, often used in outdoor or rough terrain.

Applications: Wheels are used in vehicles, machinery, toys, and various devices that require rolling movement.

Differences Between Casters and Wheels：

1. For Functionality: Casters provide a complete mobility solution, often including a swiveling mechanism for better maneuverability while wheels are basic rolling components that need additional hardware to attach to objects and provide mobility.

2. For Usage: Casters are typically used in applications where an object needs to be easily moved and often requires changing directions. Wheels are used where straight-line movement is sufficient or in combination with other components to create more complex mobility solutions.

3. For Complexity: Casters are more complex, involving multiple components and mechanisms. Wheels are simpler, often just a single rolling part.

4. For Installation:Casters are usually attached using a mounting plate or stem, involving more installation steps. Wheels are attached directly to an axle, which might be part of the object or a separate assembly.
