A small wheel on a swivel, on which furniture is supported and moved.
A wheel mounted in a swivel frame.
Angle between an imaginary vertical line drawn through the wheel centre and a line through the kingpin or its equivalent, as seen in side elevation.
The forward or rearward tilt of the projected steering axis from true vertical, as viewed from the side. This line is formed by extending a line through the upper and lower steering knuckle pivot points. For vehicles with front control arms, visualize the line extending through the upper and lower ball joints. Caster is always viewed from the side of the vehicle. When the upper pivot point is rearward of the lower pivot point, caster is positive. If the upper pivot is forward of the lower pivot point, caster is negative. When the two points are straight up and down from each other, the caster is zero. Caster is not a normal tire wearing angle and is used as a directional control for stability and steering returnability. Caster effect is necessary so that the load of the vehicle is "carried" through the steering axis line formed on the upper and lower pivot points. Here is a diagram explaining different caster settings.
A wheel alignment term referring to the angle of the steering axis in relation to an imaginary vertical line through the center of the wheel when viewed from the side.
To swivel or rotate slightly.
Swivel or rotate slightly. The tail wheel on tail draggers may be allowed to just caster. This has the added benefit of not feeding ground input back into the rudder servo mechanism.
This is another measure of chassis tuning related to the front wheels.
One complete unit consisting of all basic caster components: top plate, yoke, wheel, wheel bearing, thread guards, axle nut and washer.
a pivoting roller attached to the bottom of furniture or trucks or portable machines to make them movable
a complete wheel and horn assembly which, when attached to a piece of equipment, provides mobility for that product
a specialized type of wheel that is used in domestic, office, and industrial settings
A small wheel on a swivel attached under a piece of furniture to facilitate moving it.
The amount, in degrees, that the steering axis is tilted from true vertical backward or forward viewed from the side of the vehicle.
small, swiveling wheel used to support or move furniture and heavy objects.
A small wheel used on scenery and scenic equipment for ease of shifting. Casting Director: The producer's representative responsible for auditioning and casting performers for consideration by the director and or producer.
Another term for wheel.
In relation to front wheel alignment and steering geometry where the tyres are tilting forward or rearward of the axle pivot.
Another element of chassis tuning related to the front wheels. The front wheels are attached to the suspension at the top and bottom of the wheel assembly. The top attachment is typically set a little farther back than the lower attachment, creating caster. The more caster used, the more the wheel resists turning forces, providing stability. Too much caster makes it very difficult to steer and causes the tire camber to change excessively as the wheel is turned.
Tilting of steering axis forward or backward to provide directional steering ability. Positive caster recommended for drag racing.
The angle between a vertical line and the car's steering axis when viewed from the side, measured in degrees and minutes. Casting technology that delivers a liquid molten metal into a purpose-built mould. After cooling, the solid metal surface has the shape of the mould cavity.
The forward or rearward tilt of an imaginary line drawn through the upper ball joint and the center of the wheel. Viewed from the sides, positive caster (forward tilt) lends directional stability, while negative caster (rearward tilt) produces instability. Figure 8. Caster angle (side view)
A wheel on a swivel, attached under a piece of furniture or other heavy object to make it easier to move. The dictionary came up with this definition, not us.
Caster refers to the forward angle of the suspension's geometry. Because the tire sees added negative camber as the suspension compresses or the tires move through steering lock, increased caster allows you to run lower static negative camber.
The forward or backward tilt of a car's front wheels that, when aligned properly, will make them follow naturally in a straight line. The caster setting is what helps the car return to straight after turning a corner.
Backward or forward tilt of the king pin or spindle support arm at the top. It is the directional control angle measured in degrees and is the amount the center line of the spindle support arm is tilted from the true vertical.
The angle between the vehicle's steering axis and a vertical line, as viewed from the side.
the angle between the vehicle's steering pivot axis and completely vertical.
The deviation from vertical of the axis about which the front or steering wheels pivot. Caster is termed "positive" when the steering axis is tipped toward the rear of the vehicle, and "negative" when this axis tips toward the front of the vehicle.
Angle formed between the kingpin axis and a vertical axis as viewed from the side of the vehicle; positive caster (top of kingpin axis behind vertical) keeps wheel running along straight path; tends to return wheel to straight ahead position upon completion of a turn.
Small wheel with freely rolling ball, which is attached to each leg of a piece of furniture, allowing it to move easily.
