Chrome steel is the most common material used to produce the load carrying components in precision ball bearings, and it offers a cost-effective alternative to stainless steel. While less resistant to corrosion, chrome steel is durable and still resistant to corrosive factors in certain environments.

Welcome to Omni's multiplication calculator, where we'll study one of the four basic arithmetic operations: multiplication. In short, we use it whenever we want to add the same number several times. For instance, 161616 times 777 (written 16×716 \times 716×7) is the same as adding 161616 seven times, or, equivalently, adding 777 sixteen times. Conveniently, our tool works also as a multiplying decimals calculator. What is more, even if you have more than two numbers to multiply, you can still find their product with this calculator.

What are ball bearings made of? Ball bearing material features: Basically, ball bearing material features are made of steel balls, races, and a cage. With these three segments, ball bearings can reduce vibrate resistance while supporting a load.

Ball bearings are usually made of a kind of steel known as carbon chromium steel, which is mostly called chrome steel. There are also other steel materials that can be produced such as stainless steel, ceramics and plastic. However, each of its characteristics serve their purposes differently.

The neutral element (a.k.a. identity element) of multiplication is the number 1. This means that 1 is the (unique) number such that when we multiply any number by 1 then we obtain the same number we started with.

In essence, decimals are fractions. Therefore, one way of multiplying decimals is to convert them to regular fractions and then use the basic rule of numerator times numerator over denominator times denominator. For example,

After introducing what are ball bearings made of, now we will explain the three main components of ball bearings which are the most often heard: chrome steel, stainless steel, and ceramics. Thus, every ball bearing includes the main four parts: the outer race, inner race, balls and cage which each has its own use of purpose and characteristics.

However, it's not always that we deal with integers like 222, 181818, or 202020202020. We've learned how to multiply those and what, say, 161616 times 777 is, but how do we find the product of decimals? For example, what is 0.20.20.2 times 1.251.251.25? Is our multiplication calculator also a multiplying decimals calculator?

In this article, we will explore the significance of the ball bearing size chart and understand how to interpret and utilize it effectively.

It is commonly referred to as "bearing" in English, while in Taiwan, it is usually called "軸承". The fundamental principle of a bearing involves the placement of rolling elements, such as balls, needles, or rollers, between the inner and outer rings to facilitate smooth rotation of the shaft.

When multiplying decimals, say, 0.20.20.2 and 1.251.251.25, we can begin by forgetting the dots. That means that to find 0.2×1.250.2 \times 1.250.2×1.25, we start by finding 2×1252 \times 1252×125, which is 250250250. Then we count how many digits to the right of the dots we had in total in the numbers we started with (in this case, it's three: one in 0.20.20.2 and two in 1.251.251.25). We then write the dot that many digits from the right in what we obtained. For us, this translates to putting the dot to the left of 222, which gives 0.250=0.250.250 = 0.250.250=0.25 (we write 000 if we have no number in front of the dot).

However, say that you'd like to multiply the result further by 1.31.31.3 (remember that our tool also works as a multiplying decimals calculator).

Well, this multiply calculator sure saves a lot of time. Can you imagine writing two thousand twenty times the number 121212 like we did in the first section? We, for one, don't.

The two numbers we multiply together are called multiplicands and multipliers or just factors. The result of the multiplication is called the product. For instance, in the multiplication problem 3 × 5 = 15, the number 3 is the multiplicand, 5 is the multiplier, both 3 and 5 are the factors, and 15 is the product.

However, note that we can always invert the process of finding the product with multiplication. In other words, the 242424 times 555 can also mean adding 555 twenty-four times:

All in all, we've seen how to multiply decimals in three ways. To be perfectly honest, the first two were pretty much the same thing; it's just that the intermediate steps were in a different order. Nevertheless, this concludes the part about how to multiply without a calculator. Now let's describe in detail how to do it with one, and to be precise, with Omni's multiplication calculator.

When chrome steel is unprotected to moisture in the air, this will cause the steel itself to corrode damaging the rotation of the bearing.

Note: If you'd like to see step-by-step solutions to multiplying large numbers, check out Omni's long multiplication calculator or partial products calculator.

Of course, we could have also found easier equivalent fractions to the two given before multiplying. In this case, we could have said that 0.2=1/50.2 = 1/50.2=1/5 and 1.25=5/41.25 = 5/41.25=5/4, so

Also, our multiply calculator only deals with numbers, but mathematicians figured out how to multiply other objects. Below we list a few other multiplication calculators from Omni.

The inner and outer races and a set of balls. Both races contain a ring in its race with a groove where steel balls remain. Apparently, steel balls will be having a direct contact with each race at a single point. Inner races are found on the inside of the balls and on the other hand, outer races are found on the outside of the balls. The balls within a certain ball bearing are sandwiched between these two types of races. These two races also rotate in an opposite direction to maintain its rotation.

Stainless steel bearings provide several significant benefits when other materials cause problems because stainless steel particularly offers greater chemical and corrosion resistance, along with better stability in high temperature environments. It has the same deep raceway grooves and close conformity between raceways and balls as standard deep groove ball bearings made of carbon chromium (rolling bearing) steel.

It's always our choice how to multiply the numbers since the result is the same either way. In mathematical terms, this means that the product or multiplication is a commutative operation. Note that the same is true for addition. On the other hand, it does not hold for, say, subtraction.

Product is the result of carrying out multiplication: when we multiply two numbers (multiplicand and multiplier), we obtain their product.

Both answers are correct; it's always your choice how to multiply decimals. However, besides the two mentioned, there is another.

In contrast, Ceramic ball bearings are made of ceramic rather than steel. Full ceramic ball bearings constructed entirely of ceramic material. The inner and outer races and balls are both made of Silicon Nitride (Si3N4) or Zirconium Oxide (ZrO2). The main characteristics are it provides higher hardness and better elasticity compared to chrome steel bearings. Furthermore, this type of bearings can be run completely dry, with excellent corrosion resistance allows them to run in concentrated acids, and totally submerged in seawater without corroding. Also, it is more suitable for temperature changes, the life cycle of full ceramic bearings is much longer than steel bearings.

We could just clear out the fields and write the answer from above into one of the factors, i.e., input a1=24240a_1 = 24240a1​=24240 and a2=1.3a_2 = 1.3a2​=1.3. Alternatively, we can simply select many numbers under Multiply..., which lets us find the product of multiplication for more numbers. If we do so, we'll get the option to input a1a_1a1​, a2a_2a2​, a3a_3a3​ and so on up to a10a_{10}a10​ (note how initially only a1a_1a1​ and a2a_2a2​ are there, but more variables appear once you start filling the fields). It's then enough to input:

Product and multiplication refer to the same thing: the result from multiplying numbers (or other objects, for that matter). Fortunately, the process is very simple: it boils down to adding the value a suitable number of times. For instance, 242424 times 555 means that we add 242424 five times, i.e.:

A sleeve bearing (also known as a bushing bearing or plain bearing) is a straightforward and fundamental type of bearing. It primarily consists of an inner metal sleeve (known as the bushing) and an outer metal sleeve. Between these two sleeves lies a layer of special lubricating material, typically a sliding surface coated with grease or oil.
