Learn Something About Stainless Steel Casters

By Grace Rivas


Stainless steel casters are certain undriven, double, compound, or single wheels meant for mounting at the base of bigger objects also called vehicles. Their primary function is to make the motion of the vehicles they are mounted onto easier. They may be made from other materials like nylon, rubber, aluminium, and plastic apart from stainless steel. Some latest models combine various materials.

These commodities have a many applications in many different places. Some the areas where they are utilized include on theater and health equipment, material handling equipment, office chairs, and shopping carts among numerous others. Heavy duty, high capacity versions are applied in industrial applications for several uses such as tow lines in firms, assemblies, and platform trucks. They are known to work best on flat and smooth surfaces.

Stainless steel casters come in a variety of models including rigid, braking and locking and swivel caster wheels. A caster can be installed in a way as to roll following a straight course. In such a situation, they are fixed on a stationary point that does not change direction. Some models are installed on a pivot so that they automatically change direction to align themselves with the direction of motion.

Rigid models comprise of wheels that are mounted onto a motionless fork. The orientation of the fork is determined at the time the caster is being fixed on the vehicle. Normally the orientation of the fork is relative to the object it is fixed on. This product tends to limit vehicle travel so that it only moves on a straight path. The wheels normally resist any change in direction of movement and may need some force to do so.

A swivel caster is same as a rigid caster in every way with one simple modification incorporated to the joint right over the fork. The added swivel joint permits the fork to rotate freely through three hundred and sixty degrees. This lets the wheel to revolve in all directions therefore making it simpler to move the body vehicle in all 4 directions without modifying its orientation.

Some casters incorporate braking mechanisms to prevent wheels from turning and/or moving. Braking mechanisms are made using levers which push against brake cams. Brake cams in turn push against the wheels hence stopping them from revolving. Modern makes come with braking mechanisms that stop all the wheels from rotating at once as contrasted with old ones where one had to move around them locking every brake mechanism separately.

Flutter is a major limitation on any caster. The rapid side-to-side swinging motion of one single wheel during motion is what is referred to as flutter. This condition takes place at certain velocities depending on the distance length from wheel axles and steering axes and the quantity of weight the wheels are bearing.

Distance between steering wheel and wheel axle is referred to as trailing velocity and increasing the distance may remove flutter at moderate speeds. Stainless steel casters can be bought from any store around the world. Spoilt wheels can be replaced with new ones or can be repaired.
