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.

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.

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.

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.

Railway Axle Bearings are subject to radial impact loads caused by rail joints, switches and sometimes wheel flats, as well as to the static and dynamic radial loads of vehicle weight. They are also liable to receive axial loads generated by lateral movement as trains run on curved rails or in a snaking motion. All of these loads together form complex combinations that act on axle bearings.Axle bearings must therefore be designed on the basis of not only dimensional requirements of the axle journal and bearing box geometry, but also these complex load conditions. Additionally, as axle bearings play a critical role in the safety of railroad operation, they are periodically disassembled for inspection.Roller bearings, including tapered roller bearings, spherical roller bearings and cylindrical roller bearings, are increasingly being selected to replace plane bearings in rolling stock axles based on the particular merits of each type.

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.

The LL (labyrinth-lip) seal design is based on a low-friction rubber seal principle that is applied to TBU and CTBU designs. The main features are a combination of labyrinth, lip and flinger elements and improved protection against contaminants to extend bearing service life. The frictional moment can be reduced by up to 75%, compared to a garter seal arrangement. As a consequence, the bearing operating temperature is reduced by 20 ℃, which contributes to longer grease life and energy savings. Results from the seal test, which evaluates water and dust exclusion, confirmed that the design is very effective in excluding contaminants. Long-term endurance tests have successfully been conducted under very severe operating conditions.

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.

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.

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.

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.

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.

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.

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.

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.

Garter seal as mentioned, the first tapered roller bearing units were designed to replace plain bearings. These inch size TBU designs had to match the existing relatively long journal dimension. This design enables the integration of a seal wear ring on both sides where the garter seals are riding. AAR has standardized these garter seals and seal wear rings, which are interchangeable with components from different bearing manufacturers. TEDRAIL can offer SKF seals according to AAR Manual of Standards and Recommended Practices Section H-Ⅱ[S723]-Roller Bearing Manual .TEDRAIL can also provide special LL seal designs for inch size TBUs that generate much lower friction
