When the rolling elements of a bearing run on damaged on un-lubricated raceways, this will result in excessive friction. This friction generates energy which causes the temperature of the bearing to elevate. The more significant the damage, the higher the temperature will become due to the levels of friction present.

I often build things (3D printers, skateboard wheels, bicycle parts) that use off-the-shelf ball-bearings. These ball bearings are available in nominal mm sizes, and to the limit of my measuring tools, tend to be ground exactly to size. For example, a bearing with 15mm ID and 24mm OD will have ID and OD of exactly 15 and 24mm, to my ability to measure.

The impact of bearing failure can range from mildly inconvenient to completely catastrophic, causing irreparable damage to surrounding machinery. No business wants to foot the costs of failure if it can be avoided. That’s why it’s important to be able to recognise the warning signs of bearing failure so that you can quickly identify it and schedule in repairs before the failure occurs.

Regularly checking the temperature of your bearings can alert you to a bearing failure which needs to be dealt with as soon as possible.

It's also easy to buy linear or rotary shafts ground to nominal diameters. For example, I can buy 15mm ground rotary shafts. These are usually ground to a +/- tolerance which means half of them won't fit the bearings, or the more precise ones are ground to an upper spec of 15mm and very small tolerance smaller. Usually, even with the 15mm upper spec, the size is too close to 15mm for a bearing to slide on. I have to polish the shaft down with sandpaper (destroying the nice finish) in order to get an bearing that can be assembled by sliding, such as for a bicycle hub axle.

Obviously there is in-depth engineering that goes into setting the standards and the resultant specs, but no engineering knowledge is necessary to use the guides. The skillset for installation is a mechanic's, not an engineer's.

With 36% of bearing failures attributed to issues with lubrication, it’s well known that using the wrong type or quantity of lubricant can lead to bearing failure. Contamination can also occur during relubrication when foreign particles become stuck to the end of the grease gun, entering the bearing.

A further 14% of bearing failures are caused by contamination. It could be that high-pressured washdowns have emulsified the grease, rendering it ineffective. This leads to metal-to-metal contact within the bearing, generating heat and friction.

Adding grease to a bearing which is suffering from issues due to lubrication problems may seem like a good fix. In fact, it’s only masking the issue. You’ll need to determine the severity of the problem using data such as temperature and vibration and replace the bearing before it leads to catastrophic failure.

If your bearing is suddenly noisy during operation, you’re looking at a bearing failure. This excess noise is created when the raceways of the bearing have become damaged, causing the rolling elements to bounce or rattle during rotation.

Condition monitoring systems are a great way to continuously monitor the health of your machinery during operation, alerting you to potential issues. This can give you time to remedy the problem, preventing failure from occurring.

Shafts and bearings usually use interference or transition fits - they shouldn't slide and for installation you should use force - some kind of press or clamping tool would be best, eventually if such tools are not available - few gentle hits with a hammer (you shouldn't hit the bearing directly to avoid damage, use something, for example piece of wood, to spread the force onto the whole bearing). Alternatively, you can heat/cool one of the parts to make use of thermal expansion.

At ACORN, we supply the SKF range of condition monitoring equipment, from stroboscopes and vibration sensors to full condition monitoring systems which integrate seamlessly with your machinery for remote monitoring.

It’s important not to just replace a bearing but to look for the root cause of the failure. Performing effective root cause analysis can allow you to put mitigating measures in place to avoid future bearings meeting the same fate, further downtime and additional costs to your business.

How to tellwhich wheel bearing isbadwhile driving

Typically you want an interference fit on a bearing ID since the shaft is usually the element that's rotating and whatever the bearing OD goes into will have a looser fit. If your shaft is rotating and has a loose fit with the bearing ID it can start to score and cause a whole bunch of issues. You can typically find undersized dowels which could work in your instance.

Here are the five warning signs that you should look out for which indicate that it may be time to replace your bearings before failure occurs.

A sure sign that your bearing has failed is vibration. If the raceway surface of the bearing becomes damaged by abrasion, the rolling elements (the balls or rollers) will bounce around on the raceway surface during operation, causing high levels of vibration.

To get a bearing and a shaft which fit each other with a close sliding fit, is it more normal to use an undersize shaft or an oversize bearing? If the former, why does it seem so hard to find shafts commonly available to fit nominal bearing sizes?

In cases where you want a bearing to have a close sliding fit on a shaft, it seems two things are possible: Either you could buy special ball bearings with slightly over-nominal size (i.e. 15.15mm ID), or you could buy shafts with slightly under nominal size (14.85mm). However, there doesn't seem to be a common "standard undersize" shaft or "standard oversize" bearings for each nominal mm size; neither thing seems to be common. This leaves a world of 15mm shafts and 15mm bearings which don't fit each other except by interference fit.

Inefficient seals can also lead to particle contamination, spoiling the grease. This particle contamination may also be abrasive, causing damage to the surface of the bearing raceways.

If you become aware that the wrong type of grease has been applied to a bearing, it’s likely that failure may have already occurred. Similarly, if the bearing has been running dry due to lack of lubrication or grease has leaked through the seal due over-lubrication, it’s likely that the damage has already been done.

As for the undersize/oversize I suggest you to read some basic information about engineering tolerances. The nominal size is obviously only theory, so we use tolerances to describe the allowed variation in the actual dimenisions. Depending on the type of tolerance we allow them to be for example only higher than nominal, only lower, always higher by certain number, either lower or higher etc. And when we assemble 2 parts that have certain tolerances we have engineering fit.

If you notice your bearing suddenly vibrating during operation, it’s time to replace it. If not, you could find that catastrophic failure is not far away, causing you excessive downtime and high costs.

If you are aware that contamination has occurred within your bearing, it’s wise to replace the bearing as soon as possible. The chances are, failure has already occurred and it’s only a matter of time before this leads to further issues within your machinery.

If you notice your bearing making excessive noise while it’s running, you’ll need to replace it as soon as possible. The failure has already occurred within the bearing and machine breakdown could happen at any moment.

Standard practice is to heat the bearing with a bearing heater, or cool the shaft, prior to assembly. The thermal expansion (or contraction) allows just enough clearance for assembly. Shaft fits are also dependent on the load and application of the bearing, usually based on ISO clearances. This is a useful resource from a reputable manufacturer. For a 15 mm bearing with line to line fit or a little tighter you may be able to just use an arbor press and some elbow grease.

Bearing manufacturers will give values for interference based on the application. This does not involve buying shafts off the shelf. It involves setting the spec and having a machinist create the right sized shaft. Pump and motor manufacturers make their shafts to the right specification, which is most certainly not by buying them off the shelf. We are talking micrometers as the measurement accuracy required. All the major bearing manufacturers have guides for this (SKF, FAG, etc.). A millwright's handbook provides guidance on installation procedures. Not all bearings can be put on in a press, so field techniques also exist (yes, hammers are involved).
