Durometer Hardness Scale Skateboard Wheels

Inspiration Durometer Hardness Scale Skateboard Wheels, Durometer measures the skateboard wheels hardness.

Durometer hardness scale skateboard wheels. For example an 80b durometer is the same hardness as a 100a durometersuch skateboard wheels have a wider and more accurate hardness range. Any wheel in the 78a to 90a range is considered a soft wheel 90a to 98a is in the middle 99a is referred to as a hard wheel. Most manufacturers use the durometer a scale which is a 100 point scale that quantifies how hard a wheel is. As wheels hardened into the upper 90s on the a scale wheel companies used a modified a scale durometer to measure hardness.

These skateboard wheels have a wider and more accurate hardness range. Discover how skateboard wheels get their durometer values using testing devices. It is very similar to the a scale but reads 20 points lower allowing the useful scale to be extended by 20 points which covers the entire hardness range of skate wheels in one scale. The shore durometer is a device for measuring the hardness of a material typically of polymers elastomers and rubbers.

Durometer is basically the term for the instrument or scale used in determining the hardness of the wheel. Skateboard wheels are made from polyurethane pu and their hardness is measured in durometer. Most range between 75a to 104a. The durometer b scale is 20 points lower than the a scale and tends to be more accurate particularly for measuring harder skateboard wheels.

Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. It uses the same soft spring as the a gauge but the conical gauge needle of the d scale. Wheels manufactured throughout the 70s and 80s were much softer than the wheels ridden today so the a scale was appropriate. So when choosing skate wheels youll immediately know that an 95a wheel is harder than an 80a wheelhow the durometer scale relates to skate wheels.

As we mentioned earlier understanding the durometer scale makes it easy for you to choose skate wheels. Testing for shore or durometer is a way of measuring the hardness of a material. The a scale has been used to measure the hardness of the skateboard wheel since its inception. Another crucial factor that will defiantly have an impact on deciding the perfect skateboard wheels you need is the durometer or hardness of the wheel.

In other words a wheel marked 80b has the same hardness as one marked 100a. Skateboarding wheels use the a scale. Some brands will also experiment with dual durometer wheels for a more tailored skating experience.
