The Importance of Well Choosing a Tennis Ball

A tennis ball, He is constructed from two halves of rubber glued. During the manufacturing process or is placed plush felt also in two halves and seams are filled with liquid rubber. They have meet several technical requirements, how to maintain a minimum diameter of 6.35 and maximally 6.67 mm and a weight of 56.7 minimum and maximum of 58.5 grams.

If we talk about quality in balls of tennis, this will depend on the percentage of wool that has felt and the type of adhesive used for the union. Plush color is important, as it gives greater visibility both the player and the Viewer. In this case, it is the yellow optical of the ball.

Most of the tennis balls are suitable for all surfaces game, although some boats you will find certain surfaces. As happens with trend rackets and strings of tennis, the choice of the ball is something very personal, since we speak of feelings of each player. There will be players who prefer hard balls and players who prefer soft balls, also will depend on the level of the player, game type and runway surface. As a Council, must be taken into account that play in a regular way with worn tennis balls that have lost pressure so are most punctured either balls moist, can cause injury to the player. Therefore it is recommended to renew the often tennis balls.

Balls of tennis pressurized (duration approximately one month)

In this type of balls, the internal pressure is higher than outside pressure so there is internal pressure, this pressure is given just before gluing the two halves of the tennis ball when you add a small solid substance composed of several chemical materials that turns into gas, generating the internal pressure of the ball during the rest of the process.

We can see that over time the pressurized tennis ball loses its pressure, this affects the comfort of play, which decreases; for this reason, professional players change balls each 9 games.

Because it happens? This is because gas carrying inside evaporates little by little since the union rubber is not 100% watertight. To prevent that the tennis balls lose pressure while they’re still packaged, the boat is also pressurized. There is where the term comes pressurized tennis balls.

This type of balls are recommended for all types of players and MultiSurface are usually, it will be indicated on the packaging of the balls.

Pressureless tennis ball or ball training (duration 4 months approximately)

Here we are talking about the pressure inside of the tennis ball is equal to the external pressure, so there is no internal pressure that we found ourselves in the pressurized balls. In this way, tennis ball boot due to the own rubber since the composition of this is somewhat harder.

Advantages

Even being punctured, you can continue playing with pressureless tennis ball, since no “it loosens” after opening the package; Therefore, this does not come in pressurized pipes, but in boxes or plastic bags normally.

They have a useful life exceeding the ball pressurized, talking about 4-month comparable to the month long balls without pressurizing.

They tend to be more expensive than pressurized balls.

Disadvantages

Due to its more rigid rubber, these tennis ball are less comfortable than the pressurized tennis balls, eventually, plush wears away and the rubber hardens, making the tennis ball even more quickly. This is the signal that tells us when we have to change the ball without pressure.

This type of balls are recommended for players of initiation and that demand less comfort of play.

QUALITY OF THE FELT ON THE BALLS

Highest percentage of wool felt the ball will be more comfortable and better quality control and rebound, but must take into account that the durability of this will be lower.

Why I felt? Felt fibers make the ball in the air to follow a better path, since they overlap with the air and provide greater control, with a smooth surface the ball will fly and his career would vary by what subtract you control and comfort at the time both the beating and the flight of the ball.

MINI-TENNIS BALLS

Tennis balls have been achieved without pressure with a very low boat for young players. We found the mini tennis balls. For example the models:

-Artengo 600 ideal for the first contact with the sport in early ages.
-Artengo 700 conceived for beginners aged 5 to 8 children and adults who discover tennis.
-Artengo 710 conceived for children ages 7 to 11 and adults BEGINNERS.
-Artengo 720 conceived for children 8 to 15 years and adult BEGINNERS.

Do you see the tennis balls affected by altitude?

As you can imagine, Yes. Two are the factors that influence: the density and pressure of the air. As we go up in altitude, the air density is less up to almost 0 in space. In this way, the tennis ball moving in a less dense atmosphere has less resistance to air and moves faster.

Another factor is the atmospheric pressure. At sea level, the air that we have above our heads “heavy”. When we are at the top of a mountain, the thickness of atmosphere we have over us is lower, which “weighs less”. Thus, there is less pressure on the heights. A tennis ball is very sensitive to this change. If we take a house ball and take it back to the mountain to see how it hardens and is even slightly larger. If we take back at sea level, it becomes soft because the air that surrounds the “heavier” and crushes it. For this reason, balls at different pressures are already manufactured to compensate for atmospheric pressure.

Numbering in the tennis balls

Surely a same ball with a number printed on it and just the pot are seen from aside with another different to being the same model number. And you may have wondered what influence this on the ball? What lame, which puts the number 1 or 4? As well, that number does not affect for anything on the ball, is used to identify your tennis balls and know which are yours and which are the track of to the side.
