What is a caster in Theatre?
A caster (or castor) is an undriven wheel that is designed to be attached to the bottom of a larger object (the “vehicle”) to enable that object to be moved.
What is the meaning of air caster?
Air caster, air bearing or air cushion are all different names for the key component in pneumatic devices using compressed air to form a thin air film, on which heavy loads can be floated.
What is a caster on a chair?
What Is a Caster? Casters are small wheels that are fastened to the bottom of chair legs to facilitate their movement across floors. This type of feature is typically best suited for small, lightweight chairs such as task or conference seating.
Why are casters called casters?
As the center hub of the wheel revolves around the center of the swivel section it is said to “cast” in that small circle. Thus, caster! This essential swiveling feature of casters makes it so much easier to move heavy loads and turn tight corners in a warehouse.
What is the difference between Castor and caster?
Castor is a British term for caster wheel, whereas caster is an American term for caster wheel. A caster or castor is a pivoting roller attached to the bottom of furniture or a portable machine for easy movement. Casters are available in two different styles: swivel casters and fixed casters.
How do air bearings work?
An air bearing is a non-contacting system where a gas film (usually air) acts as the lubricant that separates the two surfaces in relative motion – typically this being a rotating shaft, and a stationary radial journal or axial thrust bearing.
How does an air pallet work?
Air Caster Solutions™ air pallets and transporters are equipped with air bearings that support and move heavy loads on a thin film of air. This air film eliminates friction, allowing loads to be moved with only 1/10 the amount of force that would be required on wheels.
What are the different types of casters?
When considering maneuverability, there are two basic kinds of caster: rigid casters and swivel casters.
- A rigid caster, also known as a fixed caster, is only able to roll forward and backward.
- A swivel caster has a raceway that allows the wheel to turn.
What is the difference between castors and wheels?
A castor wheel is a relatively small undriven wheel, meaning that it is free-rolling (as opposed to powered). They are designed to be attached to the bottom of a larger object, to enable easy movement across a floor or other hard surface. Castor wheels are often referred to simply by the standalone term ‘castors’.
Why do we use air bearing?
Here’s What the Experts Say about Air Bearings. According to Linear Motion Tips, a primary benefit of air bearings is the elimination of friction-induced wear, heat generation, and the need for lubrication. Without recirculating elements, air bearings achieve higher speeds than a ball or roller bearing.
How does air spindle work?
The pressure of the compressed air turns the rotor. To achieve even higher torque, but at lower speed, some spindles have an internal planetary gear set that reduces the speed and increases the torque. Higher speed air spindles are powered by air turbines, in which air impinging on the rotor blades turns the rotor.
What is an air pallet?
Air pallets are another form of Aluminum Transporter. They are a perfect material handling equipment for use in warehouses, and other similar environments. They are ideal for moving heavy loads that are of standard shapes and sizes.
What are glides used for?
Glides are lightweight flat feet. The key purpose of a glide is to provide stability by ensuring that the item it’s affixed to doesn’t easily slide out of place.
What are gliders on a chair?
A glider or platform rocker is a type of rocking chair that moves as a swing seat, where the entire frame consists of a seat attached to the base by means of a double-rocker four-bar linkage. The non-parallel suspension arms of the linkage cause the chair to simulate a rocking-chair motion as it swings back and forth.
What are the two types of casters?
What is air bearing spindle?
Air Spindles utilize porous media technology to create a uniform cushion of air between the rotor and stator. This enables faster rotation speeds and high-precision rotary motion with less interruption or possible down time due to zero mechanical wear.
What is an air spindle?
What is the capacity of the air casters?
The capacity per single air caster ranges from 100 to 40.000 kg’s. Next to our own range of HOVER products, we also manufacture 1 to 1 air casters replacements for all other brands. We produce all types, sizes and materials!
What is a theater caster?
Creating a theater production that transports the viewers away from their seats and into a different time and place requires several pieces of equipment, none more important than the theater caster. There are many applications for theater casters.
What are air caster transport devices?
Air caster transport devices are used to move heavy transformers and their parts during production and final placement. Both the transformers and their often heavy parts are transported very efficiently because of the high capacity and freedom of movement of the air casters. This saves time (up to 30%) and prevents floor damage.
What is an air caster skid?
Air Caster Skids can be serviced without removing the load, using the slide-out steel trays design. Our Air Caster Skid controller has been re-imagined, allowing it to be easily carried during operation and flexibility with six independent flow controls.
