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.

There are caster wheels with TPR / Rubber / Polyurethane PU material available, suitable for various environments, both workable in outdoor and indoor. 3 different sizes with different

load capacity 150kgs 300kg 500kgs of hand truck can meet your different requirements, they are widely used in office, retail, industrial, hospitality and healthcare applications.

Recently, A new customer placed an order Caster Wheel from us but he know little about caster wheel. Therefore we recommended him the right caster material according to his requirements and our professional experiences.

The most common caster wheel materials in the market are TPE, TPR, TPU. Here let’s talk about their advantages and disadvantages and you will have better understanding on how to choose TPE, TPR , TPU caster materials.

1. TPE material: TPE is environmentally and non-toxic material, with features of excellent wear resistance, elasticity, shock resistance and low noise performance. As it has good adhesion property with hard plastic. It can be coated and formed with hard plastic like PA,PP. TPE material is with great load capacity. Currently, TPE material is widely used for luggage caster,cart caster and industrial caster.

2. TPR: Technically, TPR is TPE because both of them belong to Polystyrene elastomer category. Its characteristics are similar to TPE, However, its elasticity is better than TPE as it is mainly made from SBS and its wear resistance is not as good as TPE. More important, TPR has better price than TPE, it also can be coated and formed with hard plastic like PA,PP. It can be used for heavy duty caster.

3. TPU: With the best wear resistance, good oil resistance, good elasticity and good load capacity, it has the longer service life, but it’s a bit noisy when working and without resistance to hydrolysis. It can be used for luggage caster and various types of industrial caster.

How to choose the above three caster materials?

Actually We are not able state which material is the best one since different caster materials have different advantages. The key to choose ideally caster materials depends on the usage and positioning of products. We seldom use TPE for caster even its price is moderate, mostly we use TPR and TPU. If you want the best wear resistance, then TPU is your best choice; If you want better price, then TPR is the most appropriate choice.

Ylcaster，as a professional Caster Wheel Supplier in China, has been in promoting and popularizing TPR material since 2010 and now TPR caster is widely accepted by our customers due to its good price and nice property.

Cast iron casters in today

There are many types of cast iron casters, which are mainly divided by load capactiy level. They can be divided into light duty cast iron casters, medium duty cast iron casters and heavy duty cast iron casters. The applicable range is also very wide. Like heavy duty cast iron casters, due to their strong, wear-resistant, high load-bearing characteristics, they are usually used for handling tools such as industrial trolleys. With the advent of the retro trend, they are now more used on the table, with different surface treatments and colors, used as the legs of the coffee table, coffee table, etc., and even the bed. From industrial casters to furniture casters, the style of painting is completely different.

We YLcaster is a powerful manufacturer specializing in the design, production and sales of various caster wheels. We can provide you with different kinds of cast iron core polyurethane swivel caster. In addition, it also supports various customization of casters. Friends who are interested and in need are welcome to consult and understand.

How to install casters with stem

First of all, we need to understand what is a stem caster wheel. The stem is one of the more common ways to install casters. Usually the installed object and the caster are fixedly connected by this rod. Compared with threaded stem and grip ring stem, the installation methods and the structure is simpler. Compared with plate caster wheel, the load-bearing structure is slightly weaker, so it is generally reflected in light duty caster wheel and medium duty caster wheel, which are mainly used in scenes where load-bearing requirements such as furnitures and ordinary platform trolleys are not too large. Of course, for medium duty and heavy duty scenes, the ratio is relatively small.

There are two main types of stem casters. One is a thin T-shaped stem, and some are matched with a threaded sleeve; the other is a cylindrical or square column or other polygonal column. The rod usually has a through hole.

So how to install them? The T-shaped stem is the easiest to install, just plug it directly into the set hole of the object to be installed.  It's the opposite when removing it, just pull it out. For threaded bushings, plug the bushing into the mounting hole first, and then insert the stem into place. The sleeve and the plunger act like expansion screws at this time to prevent the casters from falling off.

The principle of the inserted stem with holes is similar, except that the upper and lower diameters of the stem are the same size. After inserting in place, you need to insert a pin or other accessories into the through hole for fixing to prevent the caster from falling off when the installed object is off the ground.

T-shaped stem casters are generally smaller than columnar ones. They are usually embodied as furniture casters such as chair caster wheels and table caster wheels. Even with brakes, most of them only stop the wheel from rotating and cannot fix the direction of the caster wheel. Column-shaped stem casters are relatively larger, and are generally embodied in small and medium-sized equipment such as trolley caster wheels, shopping cart caster wheels, and even industrial caster wheels such as scaffold caster wheels, or medical caster wheels. Due to the existence of through-holes and bolts and other accessories, this type of stem casters can usually achieve the function of double brakes, while fixing the direction of the wheel and the caster.
