Product: PU wheels/pulley for skate board, 70*45mm, pink and green core, Customized

Why there are thousands of types of wheels?

The wheels have specific features of hardness, size, shape...and color, printing...

 Skateboard PU Wheels, 4 units for one set, are made of polyurethane. Wheels have different diameters, shapes and hardness. Small wheels start fast, but lack of stamina, suitable for skills; large wheels can easily glide on less flat ground. Skateboards are also very particular. In addition to bearing accuracy (such as ABEC1, ABEC3, ABEC5, ABEC7, etc.) has an impact on speed, it depends on the performance of the wheel.

Good abrasion resistance, good bounce,

 When choosing materials, it should be considered to be suitable for different ground roads, such as floor roads, cement roads, asphalt roads and so on. No matter what road you slide on, the wheel must be flexible, wear-resistant, and moderate in hardness. It must also ensure that the wheel has enough friction coefficient on the road surface.

 The first is hardness, and the skateboard wheel is usually a polished polyurethane. The proportion of polyurethane in the wheel is different, and the hardness of the wheel is also different. A wheel with a hardness of 85A(A refers to hardness) is relatively soft and suitable for rough pavement taxiing. The sound is minimal when taxiing. It is a good choice for friends who like to go shopping. However, the 85A wheel is relatively non-wearable because it is soft, and it is easy to break the interval layer when doing things such as side skid brakes. In general, today's skaters use 97A-103A wheels. This kind of hardness wheel is suitable for smooth marble and relatively flat roads, as well as U pools, platforms and other props. Wheels such as 85A at smooth leveling are also soundless. But in rough places and on the U pool, there will be a huge rumble(this sound often makes the racer boil). The transparent or translucent wheel does not use 103A. It is too hard and will burst. It is best to use only props made of all WOOD materials.

 Followed by the diameter, the 38-40 mm wheel is now used by very few people. This wheel starts and accelerates quickly, but the stamina is small, and it is only suitable for very flat roads. It is characterized by a fairly flexible movement. Friends who like small movements can try. The 45mm -50mm wheel is the most suitable wheel for the road type. 52-60mm wheels are more suitable for use on props. Because the action on the props requires strong power, the flat action hopes that the lighter the board is, and the weight on the props can sometimes bring more inertia and impact, making you taller and farther. In the wild, you can use more than 60mm of cross-country wheels. Professional mountain skateboards use large rubber wheels.

 And the rebound, the rebound of the wheel is very important. Although there are no parameters to refer to. However, the stronger the rebound, the stronger the ability to overcome obstacles. If you don't know how well your wheels bounce back, you can do a little experiment. Remove the bearings in the wheel, you throw the wheel hard on the ground, rebound the high wheel, the wheel will bounce to the ceiling, the bottom rebound wheel, will only jump on the ground two times. On the smooth ground, perhaps, the two wheels can run as fast, but in the slightest rough road, the advantage of high-rebounding wheels can be immediately demonstrated.

How to choose suitable PU wheels for your local market?

It is different for per consumer’s requirement. We are facing the times which time is money and safety is the first thing, which is a great era for someone who are seeking value of products. In this case, we developed several series of high performance for polyurethane wheels to meet customer’s will.

Customers fromAmericaand Europe need that performance of products is higher and higher. They pay more attention to excellent features than polyurethane wheel price.

In order to meet consumer’s requirement, we invested huge capitals to develop several series for PU wheels. All raw materials must be top grade. Our cost is two times as expensive as cheap raw materials price. Our technical team tested thousands of times for PU wheel with outstanding performance. At last, we succeed in high characteristics of polyurethane wheel industry.

I kindly ask for you to spend a little time to read following.

1)Wear proof type

Life of the PU wheel is very long, which is over one time longer than common one.

2)heavy-duty type

The polyurethane wheels can load more quantity than normal wheels, so consumer can save some work   time. Consumer only uses the wheel under some special condition.

3)Anti-cracking type

Consumer can use the PU wheel under cold weather.

4)Eco-friendly type

Raw materials of the polyurethane tire don’t contain any harmful component to keep air clean.

5)Comfortable type

The polyurethane wheel can reduce fatigue when consumer uses it.

Why do someone quote low price for PU foam wheels?

You can get 100 different price of polyurethane wheels if you inquiry 100 suppliers. Someone can quote very low price, and someone quote high price. Importers will be confused. How should I choose?

You must understand the point which raw materials of PU wheel is expensive. Some companies add calcium powder to raw materials to cut down production cost. They add weight of calcium powder according to quotation. In fact, buyer give any price, polyurethane wheel manufacturer can supply, but PU foam wheel quality is different.

Raw materials of PU wheels have A grade,B grade,C grade. Those very cheap PU wheel only use C grade and mix to calcium powder. Do you know calcium powder price is very cheap?

We produce only use A grade raw materials and special formula for high performance. Our company invested huge money for research of high performance PU wheel.

Do you know the standard of good PU wheel?

One of my customers said that rough surface is good. What do you think of the point? I think that most consumers don’t understand what is good for polyurethane wheel. As an expert of PU wheel, I would like to share some ideas.

Good PU foam wheel must bear features as followings:

1) smooth surface without small holes.

2) It can recover original shape under loading heavy weight.

3) Don’t crack under cold weather.

4) Long life under normal condition

If someone add some cheap materials to raw materials of PU wheel, they have no above characteristics. Do you dare to buy cheap PU foam wheel?

Do you know the best temperature for making PU wheels?

Polyurethane wheels which produce in Spring and Autumn are excellent PU wheel’s surface is smooth and pretty. It’s reasonable temperature’s range from 5 degree Celsius to 20 degree Celsius.

Why do PU wheels that produce in Summer and Winter is poor surface?

It contain more water in air in Summer, in same time, raw materials of polyurethane wheel also hold more water.

In very cold winter, foam temperature is too low, so foam effect is also poor.

I advise that customers place PU wheel order in Spring and Autumn.

If you have also other ideas, don’t hesitate to send me e-mail, then I require our technical team research and develop them to meet your personal requirement.
