What are the two types of 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 are frog legs on a wheelchair?
Frog Legs Shock-Absorbing forks eliminate 76% of all shock and provide the front casters the ability to lift back, up and over obstacles to minimize pitching.

What is caster housing?
The housing connects the chair base to the wheels and essentially carries the entire load of the caster, cantilevered from the vertical axis of the stem to the horizontal tangency where the wheels meet the floor surface.
Is positive or negative caster better?
Performance Benefits of Positive Caster You get better handling when cornering, better stability at high speeds, and better straight-line tracking. The better traction while cornering is similar to a vehicle with negative camber, as it keeps more tread on the ground despite the sharp angles.
What happens if caster is off?
If you don’t have enough positive caster (forks too little angle toward the front) the car will wander and feel unstable. If you have too much positive caster, the vehicle will be harder to turn. However, just like with camber, vehicle pull is not caused by too much or too little caster, but by side to side imbalance.
What type of casters are best?
Soft casters are best for hard surfaces, like tiles, hardwood, and laminate. Meanwhile, hard casters suit softer floor surfaces. As such, for carpeted flooring, the best option to go with is hard tread casters. Hard casters require less force to roll and move around.
How do I choose the right caster?
To determine the load capacity for each caster, divide the combined weight of the equipment and maximum load by the number of casters to be used. This is the load that each caster and wheel must support. Always select a caster and wheel that are rated for a capacity greater than the calculated load per caster.
