Bearingcode meaning
If you are looking for a proper bearing match or replacement, you will also need to pay attention to some other important aspects of the bearing number to find the correct bearing. The suffix can contain a few details about the bearing design and features:
Bearings are measured by their inner diameter, outer diameter, and width; the size of a bearing is normally listed as such: ID x OD x W. These measurements are normally taken in millimeters, but can be converted to inches. In fact, most manufacturers and suppliers offer bearing measurements in both imperial and metric systems.

Most of the time, wheel bearings fail when the seal protecting them breaks. This allows heat, water, dust, and other debris to enter the hub assembly, where it can contaminate the lubricant that keeps your bearings moving smoothly while you drive. This contamination can eventually cause the bearings to rust, which prevents them from moving smoothly against each other and creates friction within your hub assembly—putting strain on your driveshaft and ultimately your transmission.
As stated before, size depends on the shaft size and application requirements. Bearing size can greatly impact the performance and capabilities of a ball bearing; therefore different sizes are used in different industries.
We know all about wheel bearings, why they fail, and when they need to be replaced. Read on to learn about 8 common signs of wheel bearing problems so you can recognize a failing bearing in your own vehicle and order a high-quality replacement for it before it leads to other problems.

You may not think about the wheel bearings in your car often—but when there’s a problem with them, it’ll cause issues that make driving noticeably harder. Of course, figuring out exactly what issues come from worn-out wheel bearings can be difficult for people without a lot of mechanical experience. That’s why we’re here to help.
Each combination of these measurements corresponds to a series number, usually located directly on the bearing. Ball bearing size charts are widely available, and can be used to find the measurements of a specific bearing. Series 6200 and 6300 are the most commonly used, and typically range from 10 x 30 x 9 mm (.394 x 1.181 x .354 in) to 150 x 320 x 65 mm (5.906 x 12.598 x 2.559 in).
When bearings wear out or lose their lubrication, they can create a grinding noise. This noise is normally more noticeable when turning your vehicle to the side with the worn out bearing on it. If you hear grinding, loud humming, or rumbling coming from your vehicle during turns or while accelerating, there’s a good chance your bearings are due for replacement.
Enough wear and tear on your drive axle can eventually affect the way your vehicle steers. If you notice that your vehicle no longer handles as responsively when turning the wheel (especially if it’s more prominent on one side, since bearings on both sides of a vehicle rarely wear out at the same time), have the bearings in your car checked by a professional mechanic ASAP.
That wobbling we just mentioned will probably first be noticeable in your steering wheel. You might not feel as though it’s much of an issue at first—but if you don’t replace the bearings soon, the friction will increase and can cause your entire car or truck to vibrate. In these cases, it’s best to replace the bearing ASAP to prevent unnecessary friction on your driveshaft and the rest of your transmission.

When the wheel bearings on one side of your car begin to fail, they’ll cause more friction in the hub assembly of the wheels they’re attached to. As a result, that wheel won’t turn as fast as the one on the other side of your vehicle—which means the tires won’t wear evenly on both sides.
If you suspect a problem with your wheel bearings, one good rule of thumb is to take a closer look at the rubber on your vehicle. If the tires are balding on one side and have plenty of tread on the other, a worn-out bearing is likely the culprit.
In many newer cars and trucks, wheel hub assemblies also contain the sensor for the anti-lock braking system. When the bearings inside the hub assembly fail, the ABS sensor on your dashboard may turn on.

One of the first signs of worn out wheel bearings you should look out for is what feels like a reduction in your car’s power. Worn out bearings often create significant wobbling in vehicles, which can make your car unsteady above certain speeds and create friction that prevents them from accelerating properly.
You might think this is just an annoying light on the dash you can ignore while driving, but we strongly recommend against doing so (or driving while any of your dashboard’s warning lights are on). The ABS sensor determines when your anti-lock braking system engages—and if it detects significantly more friction on one side of your vehicle than the other, it may turn ABS on when you’re not expecting it, creating a serious safety hazard.
When wheel bearings wear down and stop moving smoothly, they may produce a clunking or banging sound. Often, this is only noticeable when a bearing has experienced significant wear and tear—although it can also be apparent when travelling over surfaces with uneven patches.
Generally, smaller ball bearings have more limited load capacities. They are used in applications where space-efficiency is more important than load capacity. Miniature bearings, often constructed as precision ball bearings, are used for extremely small applications, such as medical instrumentation, robotics, or semiconductor equipment. On the other hand, larger bearings have greater load capacities. They are used for heavy-duty industries such as agriculture machinery, mining and drilling equipment, or heavy power tools. Many manufacturers also offer custom bearing size options for very specific applications that have unique requirements.
Ball bearings are available in all different sizes, depending on the shaft size and requirements of the application. As they are used in all types of industries, they are needed for a large variety of application sizes, from skateboard wheels to oil drills. How are these bearing sizes determined?
Wheel bearings just aren’t meant to last forever. In general, it’s a good idea to replace them every 85,000–100,000 miles (roughly 136,000–160,000 kms). Of course, the lifespan of your wheel bearings also depends on the quality of the products you buy—our high-quality aftermarket replacement wheel bearings are designed to last significantly longer than the cheapest options you’ll find online.
It is not uncommon that the bearing identification number may be illegible or worn completely after long term use, requiring a bearing to be measured manually. This can easily be done using a vernier caliper to easily provide accurate measurements. If this tool is not available, measurements can be taken carefully using a ruler.
Each manufacturer may use unique suffix codes; it is best to look up a suffix guide to find the correct bearing match or replacement.
Even in cars without ABS, driving with worn-out bearings can cause major handling problems. Enough friction on one side of the car can result in your vehicle pulling to one side. This can make turning in one direction much more difficult than the other, reducing your ability to manoeuvre in potentially dangerous situations. It can also cause you to drift to one side while driving in a straight line unless you’re constantly applying pressure in the opposite direction—which can cause you to become fatigued more quickly, making longer drives less comfortable and much less safe.
