There are 3 ways for the measurement of bearings. That is the Inside Diameter (ID), Outside Diameter (OD), and width (W).

Here’s something your car shouldn’t do: Shake. If your steering wheel is bouncing around like popcorn kernels in the microwave, you’ve got an issue. And that issue is a lot less fun than a bag of popcorn. Busted rear wheel bearings will sometimes make for a car that isn’t driving right, and some abnormal pressure and stress will head through the steering system, into your car’s cabin.

Bearingcodes and sizes

In the end, sealing indicates the type of shielding done in bearing. ZZ or 2Z is the type of metal bearing. And, 2RS, 2RS1, 2RSR are the types of rubber bearings. This demonstrates the entire bearing number nomenclature.

Bearingseries code

Clearance is the total distance between the inner rings to the outer ring. Such as, when one among the rings is rotating and the other is fixed. Bearing clearance is of 5 types normal clearance, standard clearance, C2, C3, and C4.

If you ignore everything in this article, then here’s what you’ll end up with: Three wheels. The rear wheel bearings will give you signs of aging as they start to die. Once they fully die, they’ll actually disintegrate, and then the wheel has no way of being supported. And at that point it will fly free.

It is easy to understand the bearing numbers. Bearing numbers shows the difference in shape, size, toughness, etc. It will help you in choosing and determining the required bearing precisely. Before that, it is essential to remember the codes as well as numbers. Follow the bearing number and size chart and identify your bearings.

Bearing numbers is essential in choosing the required bearing type. It contains the supplementary codes and basic numbers. The bearing number code can also be termed as the sub-divisions of bearing. The sub-division demonstrates the types of bearing with numbers, series, bore type, and sealing.

Among them, normal clearance and C3 are the main clearance. The normal clearance shows no suffix. Standard clearance has no suffix as well as the prefix. C3 delivers faster running speed and higher temperature with no failure. C2 is less than standard clearance. At last, C4 shows an outcome faster than C3.

So, here’s what will happen if one of your rear wheel bearing starts to kick the bucket. You’ll end up with one wheel not being used the right way, because it’s not supported properly. That means the car won’t drive right, and the wear will be uneven. One rear tire will likely be worn more than the other, and the pattern of the wear will certainly be different. It’s always a smart idea to pay attention to your tires. Give them a visual inspection every now and again, so that you can spot excess wearing, bubbles, low tire pressure, or uneven wear and tear. It can help you spot a big issue, like a rear wheel bearing failure.

Ever drive a car with three wheels? And no, that’s not a challenge. If you’re experiencing any of the symptoms above, it’s likely time to get your rear wheel bearing replaced.

In another case, the bearing number is 6305ZZ. That actively demonstrates that the third and the fourth digit is the bore size. Equally, 05 is the bore size. Therefore, 05 are equal to 25 mm of the bearing bore size.

Every bearing is composed of different codes and numbers. In the case of tapered bearing, the code is 32/ T. roller bearings and ball bearings are of several categories. Each category carries different codes as well as numbers. To know the codes of the bearing types, follow the given bearing specification chart below:

In the case of understanding the bearing size, it is necessary to learn the components precisely. Such as each bearing carries different codes which determine the type. The medium toughness of the bearing is observed by the bearing series. The bore no. describes the inner diameter of the bearing. The diameter is measured in millimetres.

In the case of Inch Bearing, the first digit must be ‘R’. ‘R’ also indicates the size of the bearing. That must be 1/6th of an inch. For example, R4-3RS is the bearing number. Here, R4 indicates the inch bearing. R4 also denotes the bore size of the bearing. Mainly, R4 is equal to 4/16 or 1/4th of an inch.

Following table 2, 03 is equal to 17mm bore size. ZZ is the type of metal shielding. That indicated that the bearing is shielded on both sides. In the end, C2 describes the clearance code that is less than standard.

Secondly, the bore size of the bearing. Bearing size is calculated by the relevant dimension. It is measured in millimetres. The third and fourth digit of the bearing number describes the bore size. The bore size varies from 0 to 3 which indicate 10 to 17 in mm. In this case, if there is no fourth digit in the bearing number, the third digit will denote the bore number. For example, the bearing size is 234. So, that actively demonstrates that 4(=4mm) is the bore size.

Well, this one should be obvious. If your car is making a funny noise, something is likely wrong. If your rear wheel bearings are starting to go, you could hear any number of noises, from growling, to groaning, to grinding and scraping. The important thing to note is that the noise will be coming from the rear wheels. That’s your clue that it may be the rear wheel bearings.

If you drive your car nearly everyday, you’re probably familiar with how it feels…and especially when it feels different. The handling in your car may start to shift if you have a dying rear wheel bearing. Your car will start to feel loose, which is really the feeling of your wheel starting to become disconnected and loose. Not a good thing. And not a good feeling. You’ll also likely feel your car pulling a little bit to the left or the right - depending on which rear wheel bearing is dying - when you’re trying to drive in a straight line.

Bearings provide major importance in various mechanicals. They are available in different sizes and measures. Bearings contain numbers as well. The numbers help in the process of identification. Bearing numbers are also termed pattern numbers. As a top bearing supplier in India, we feel the need to educate non-technical persons having requirements of bearings. Today, we will discuss the bearings and how to identify bearings by numbers?

Schedule a time that works best for you and we’ll come to your home or office to complete the repair. Or drop it off at one of our local shops.

The calculation of bearing size is easy to understand. For example, the bearing no. is 6203RS. Here, 6 signify the bearing type whereas 2, 03, and RS signify the bearing series, bore type, and sealing. The calculation of the bearing size undergoes several procedures:

Let’s know the procedures for the identification of the bearings. 6203ZZC2 is the bearing number. From ‘62’,’ 6’ describe the type of bearings. By following table 1, it indicates that it is a single-row deep groove ball bearing. ‘02’ indicates the bearing series. By following Table 4, it indicates that it has light toughness. Here, 03 describes the bore number.

Bearing calculation is the easy identification of the type of bearing. Mainly, in the case of supplementary codes. Consequently, the calculation is different for inch bearing.
