What are the common failures of spherical roller bearings

Alright, folks! As a supplier of spherical roller bearings, I've seen my fair share of issues with these little mechanical marvels. In this blog, I'm gonna talk about the common failures of spherical roller bearings.

 

Let's start with one of the most prevalent problems: lubrication issues. You see, proper lubrication is like the life - blood of spherical roller bearing. If there's not enough lubricant, it can lead to a whole bunch of headaches. Without sufficient lubrication, there's increased friction between the rolling elements and the raceways. This friction generates a ton of heat, which can cause the bearing material to expand and distort. Over time, this can result in premature wear of the bearing surface. You might end up seeing things like pitting, where small holes start to form on the raceways or the rollers. And let me tell you, once pitting sets in, it's a slippery slope towards complete bearing failure.

Moreover, if the lubricant is contaminated, that's also a big no - no. Dirt, dust, and metal particles can get into the lubricant. These contaminants act like little abrasives, scratching and wearing down the bearing surfaces. You can check out The Bearings CA to learn more about how to prevent lubrication - related problems in these bearings.

 

Another common culprit is misalignment. Spherical roller bearings are designed to handle some degree of misalignment, but there's a limit. When the shaft and the housing are not properly aligned, it puts uneven stress on the bearing. One side of the bearing might be taking on more load than the other. This uneven stress can cause the rollers to skew, and they won't roll smoothly along the raceways. As a result, you'll notice increased wear on one side of the bearing, and the bearing's lifespan will be significantly reduced.

In extreme cases of misalignment, the rollers can even start to skid instead of rolling. This skidding causes heat build - up and can lead to surface damage. If you're dealing with a situation where misalignment is a concern, you might want to look at Spherical Roller Bearing CC. It has some features that can better tolerate certain levels of misalignment.

 

Overloading is yet another major failure mode. Sometimes, the application requires a bearing to carry a load that's beyond its rated capacity. When this happens, the bearing is under a lot of pressure. The rolling elements and the raceways can start to deform. You might see flattening of the rollers or indentations on the raceways. This deformation disrupts the smooth operation of the bearing and increases friction.

Over time, the overloaded bearing will experience accelerated wear and tear. Eventually, it can lead to a breakdown. It's crucial to accurately calculate the load requirements of your application and choose the right bearing. Our Spherical Roller Bearing MB Type is engineered to handle specific load ranges, so you might want to take a look at it for more suitable options.

 

 

Let's also talk about corrosion. If the bearings are exposed to a corrosive environment, such as high humidity, water, or chemicals, it can spell disaster. Corrosion starts to attack the metal surface of the bearing. It can cause rust spots to form, and these rust spots can grow and spread. As the corrosion progresses, it weakens the bearing material. The rollers and the raceways can lose their smooth finish, and this leads to increased friction and reduced performance.

Preventing corrosion often involves proper sealing and using bearings with corrosion - resistant materials. We offer a variety of solutions to deal with corrosive environments, so don't hesitate to reach out if you have such requirements.

 

Another issue that can sneak up on you is fatigue failure. Spherical roller bearings are subject to cyclic loading during their operation. As time goes on, the repeated stress can cause small cracks to form on the bearing surface. These cracks start out tiny, but they can propagate over time. Once the cracks get big enough, pieces of the material can break off, leading to spalling. Spalling is a sign that the bearing is on its last legs.

Manufacturing defects can also contribute to bearing failures. Sometimes, there might be issues with the material quality, such as impurities in the steel. Or there could be problems during the machining process, like incorrect dimensions or poor surface finish. These defects can weaken the bearing and make it more prone to failure.

 

First of all, proper installation is key. Make sure the bearing is installed correctly, with the right amount of interference fit and proper alignment. Regular maintenance is also crucial. Check the lubrication levels, look for signs of wear, and monitor the operating temperature of the bearing.
