Designed with grooves in the outer ring to offer more protection (than our L-type seal) against contamination and direct spray liquids. Liquid gets pushed out through outer grooves when in rotation.

To grease a bearing with PTFE, the surface needs to be cleaned with a non-residual solvent, a compatible preservative put on the bearing surfaces and the specialty grease properly applied. This will ensure good lubrication adhesion to the precision bearing surfaces, which will in turn provide a long application life.

Normal wear and tear over time can result in bearing noise.  Additionally, damage due to inadequate handling, shock loading, or operating conditions beyond the bearing's limits can also lead to sudden noise issues.

A wild card in choosing a ball bearing lubrication is dry lubrication. This category can include hard coatings, malleable coatings, or even precious metals.

Bearing misalignment occurs when the bearing's internal and external components are not correctly aligned with each other or with the shaft.  Misalignment puts excessive stress on the bearing, leading to increased friction and noise generation.

Overloading refers to subjecting the bearing to loads beyond its designed capacity.  Excessive loads cause increased stress and can lead to bearing noise, deformation, and premature failure.

In looking at an internal combustion engine for vehicles or stand by generators, the bearings within the starter pulley are most likely grease lubricated. These bearings are relatively open to the atmosphere and creating the oil circulating system would be very difficult. Conversely, most turbochargers on these engines already have oil circulation for both the bearings and cooling effects.

Regularly check and maintain proper lubrication levels in bearings according to the manufacturer's guidelines.  Use the recommended lubricant type and ensure that it is applied correctly to all necessary points.  Implementing a proactive lubrication maintenance program can help prevent noise-related issues.

Some common materials are Molybdum DiSulfide, Tungston DiSulfide, Dicronite, Gold, and Silver. The cost for these lubrications can be quite expensive and not all bearing companies have the equipment and/or experience to apply them properly.

Choose from our selection of 6901-2RS bearings, including ball bearings, roller bearings, and more. In stock and ready to ship.

During installation or maintenance, ensure proper alignment of the bearing with its mating components and the shaft.  Use alignment tools and techniques recommended by the equipment manufacturer to minimize misalignment issues.  Regularly monitor the alignment and take corrective action if misalignment is detected.

A downside to these lubrications is minimum application life. Generally, one should expect less than 1000 hours of lubrication life, much less if the application is high RPM. Dry lubricants are used quite often for touch down bearings, some space applications, and commonly in environments with high levels of exposure to chemicals – such as refrigerants.

One of the primary reasons for sudden bearing noise is a lack of proper lubrication.  Bearings require adequate lubrication to reduce friction and prevent metal-to-metal contact.  When bearings are not sufficiently lubricated, the friction between the rolling elements and raceways increases, leading to noise generation.  Additionally, insufficient lubrication can result in overheating, accelerated wear, and premature failure of the bearing.

Regularly inspect bearings for signs of wear, such as pitting, scoring, or discoloration.  Replace worn or damaged bearings promptly to avoid further complications.  Implement proper handling and maintenance practices to minimize the risk of damage.

A proper greased bearing break in procedure will ensure the right amount of grease remains in the raceways, a good grease collar is formed, and temperatures are stabilized. There is a good precision ball bearing break in procedure here.

Verify that the bearing is appropriately sized for the intended load and operating conditions.  Consult bearing manufacturers' catalogs and engineering guidelines to determine the correct bearing type and size.  If overloading is suspected, consider upgrading to a bearing with a higher load capacity or reassess the equipment's design.

Many bearings that are used in space have a grease lubricant because of the low temperature and no-maintenance requirements. Greases designed for space applications have a very low viscosity even at low temperatures to keep efficiencies as high as possible.

Both oils and greases have capabilities for extremely low and high temperatures. The differences will be in viscosity, overall temperature usage range, chemical compatibilities, chemical resistances, and maintenance cycle and bearing life requirements.

Bearings play a crucial role in various mechanical applications by reducing friction and enabling smooth rotational motion.  However, occasionally, bearings can develop noise-related issues, causing concern for equipment operators and maintenance personnel.  Understanding the reasons behind sudden bearing noise can help identify potential problems and take appropriate measures to address them.  In this article, we will explore the common causes of sudden bearing noise and discuss potential solutions.

A sleeve bearing (also known as a bushing bearing or plain bearing) is a straightforward and fundamental type of bearing. It primarily consists of an inner metal sleeve (known as the bushing) and an outer metal sleeve. Between these two sleeves lies a layer of special lubricating material, typically a sliding surface coated with grease or oil.

Sudden bearing noise can be indicative of underlying issues that, if left unaddressed, can lead to severe damage and equipment failure.  By understanding the common causes of bearing noise and implementing appropriate solutions, operators and maintenance personnel can ensure smooth and reliable operation of machinery.  Regular maintenance, proper lubrication, contamination control, alignment checks, load considerations, and early detection of wear or damage are crucial in preventing sudden bearing noise and maximizing the lifespan of bearings in mechanical systems.

Now that you have potentially chosen the type of lubrication for your application, the next task is figuring out which is best. Commonly companies will have a few ‘go-to’ lubrication options that are used internally, this is a great starting point. Other aspects to take in to account of application/bearing temperatures, n*dm speed factor (RPM * diameter of balls, provided in catalog here), time before usage, cost, availability, etc.

Another common cause of sudden bearing noise is the presence of contaminants, such as dirt, dust, or water, within the bearing assembly.  Contamination interferes with the smooth operation of the bearing by causing abrasive wear and creating irregularities in the rolling surfaces.

Take preventive measures to minimize the ingress of contaminants into the bearing assembly.  Implement effective sealing mechanisms to protect the bearing from external elements.  Regularly inspect the working environment and take necessary actions to reduce contamination risks.  If contamination is suspected, clean the bearing thoroughly following appropriate procedures and replace the lubricant.

First, bearings are either delivered pre-greased from the factory or with a preservative oil lubrication film. If you are greasing the bearing yourself instead of a bearing industry professional, you need to be positive that the grease being utilized is compatible with the oil preservative from the factory. If it is not compatible, the grease will not have proper adhesion to the bearing surfaces and will slide out of the bearing causing premature failure. This is common with PTFE and other specialty greases that are not compatible with many preservative oils.

Another interesting application is CNC spindles. Metalworking spindles traditionally use oil lubrication with set feed rates, return lines, and a reservoir for cooling the oil. These high duty cycle metal working spindles sometimes require the added cooling effect on the bearings that this oil circulation provides.
