How Do Miniature Bearings Compare?

Friday, September 23rd, 2016

Miniature ball bearings, also commonly known as Instrument bearings, play a role in an extensive range of applications.

In general, bearings are in the types of devices that allow for specific parts to move in relation to each other in a controlled fashion. The motion can be in rotation or linear. One prominent type of bearing is roller bearing.

Bearings in Agricultural Applications

Friday, September 25th, 2015

Agriculture has been at the heart of civilization since it dawned on our ancestors that food security is critical to our livelihood.

Once it was determined that a place had good food security, we began settling and growing villages. And with the growing responsibility to feed a larger community, agricultural technology began to advance as well.

Fast forward to today. There is still food scarcity present in countries all over the world. The machinery used in agricultural endeavors plays a vital role in producing efficient and stable yields so that we can continue to feed our growing communities.

Tractors

Tractors have become a primary asset in crop production and handling. And, depending on the size of the operation, they can be quite large beasts of burden.

A tractor needs to be able to operate efficiently in all types of weather and ground conditions. This can mean ensuring resistance against seal contamination from foreign debris, operating in excess mud and water, and a high potential for misalignment.

To continue to be economical, it’s also important that the tractor and its parts endure a long life, even through such harsh operating conditions.

Bearings are used in many components, including the engine, transmission, and wheel hubs of a tractor. Operating successfully, these bearings help pull and power the tractor by getting more horsepower to the ground.

Balers

Idle for most of their life, balers can be subjected to other harsh conditions during downtime, such as humidity.  This is problematic for its inner workings, especially since farmers rely on their machines to be top-notch when called on for their part.

At work, balers must operate constantly through a storm of dust. Its bearings are supporting pulleys and must continue to be reliable. Effective sealing is critical to bearing life when it comes to this machine. With proper sealing, contamination is less likely and will be less harmful.

Combines

The combine operates in the greatest extremes of all farm equipment. It lays idle for most of the year and then is called upon to be heavily operated for only a short amount of time. The wear and tear endured during operation, coupled with the amount of downtime this machine experiences puts unique strain on the bearings and other inner workings.

Like all other agricultural equipment, combines need to be utterly dependable. Unexpected maintenance and downtime can be costly not only to the farmer’s pocket, but also to the community they feed.

Combines also operate in dusty, muddy, and harsh weather and grounds conditions. Bearing designs must keep up, and seals must be ultra-reliable for these machines to do their part in the harvest.

Products and Solutions

Everything you need in agricultural applications can likely be found through NSK, Timken, and NTN. These powerhouse companies have the capability of specializing in multiple industries, and agriculture certainly is one of the largest.

There are new and innovative specialized bearings, lubricants, seals, and sensors being introduced to the market with each passing year.

Lubrication of Bearings

Friday, January 24th, 2014

When a bearing is required to run under demanding conditions, the choice of lubricant is vital. Lubrication has a big impact on lifespan, torque, speed, noise, grease migration out gassing, temperature, and rust prevention of the bearing.

Proper lubrication paves the way for smooth running of equipment, with only mild wear, and without unnecessary stresses at bearings. When lubrication fails, metal or other components tend to rub destructively over one another, leading to destructive damage, heat, and failure.

Synthetic Industrial Grease

Friday, November 15th, 2013

Synthetic industrial grease is created for a wide array of applications, whether for industrial, construction, agriculture or automotive purposes. As much as you can, you should choose one that can withstand extreme-pressure and one that has anti-wear additives and corrosion inhibitors.

Synthetic greases are particularly ideal for wet-end paper machine bearings, press-section bearings, and felt-roll and calendar bearings. Generally speaking, they also work well with calcium, calcium 12-OH stearate, calcium sulfonate, lithium and lithium-complex thickened greases.

An important note: see to it that you always comply with equipment manufacturer’s recommendations regarding lubrication frequencies. Otherwise, premature equipment failure is imminent.

Before changing greases we suggest that all previous grease be removed from the application. Then cut the lubrication interval in half for the first lubrication cycle prior to continuing the normal lubrication interval. This will help ensure that there are no compatibility issues and that your change is most effective.

You can apply synthetic industrial grease from ambient temperatures of -40° F to +356° F (-40° C to +180° C), depending on the lubrication system design as well as method of application. The operating temperature range is very close to this range as well.

Like almost anything else, synthetic industrial grease should have proper handling and storage. It should be kept in a dry area avoiding heat and open flame.

In terms of shipping and disposal of synthetic grease, you should always adhere to governmental regulations. Also, never reuse a container for something else.

Is synthetic oil lubrication recommended for tapered roller bearings?

Friday, July 19th, 2013

Q: Do you recommend synthetic oil lubrication for tapered roller bearings? 

A: The usage of synthetic lubricants with tapered roller bearings is generally OK, assuming the lubrication has the right additives for your specific application requirements. There are cases wherein synthetic greases are superior to petroleum-based oils when it comes to their capacity to fight breakdown from mechanical and thermal conditions.

Nevertheless, it is good advice to always consult the original equipment manufacturer in regards to any change from a lubricant that is specified by them. Before you opt for synthetic oil grease for your application, touch base with your sales or service engineer so you can rest assured it is acceptable in your application.

About Bearing Lubrication

Monday, July 8th, 2013

When a bearing runs under extreme conditions, the lubricant selection is vital. Lubrication will have a huge impact on life, torque, speed, noise, grease migration, out-gassing, temperature and rust prevention of the bearing.

The two main types of lubricants are oil and grease. Oil is the main lubricant used for ball bearings. In the past, the majority of lubricating oil was refined from petroleum. In this day and age, synthetic oils like diesters, silicone polymers, and fluorinated compounds have become commonplace.

On the other hand, grease is an oil where a thickener has been added to in order to keep oil from migrating away from the lubrication site. It is utilized in cases where frequent replenishment of the lubricant is impossible or undesirable. The operative properties of grease rely heavily upon the base oil. Other elements being identical, grease usage instead of oil yields higher starting and running torque and can limit the bearing to lower speeds.

Petroleum Mineral Lubricants

Petroleum lubricants are known for their outstanding load carrying abilities and are excellent against corrosion. However, they are useable only at moderate temperature ranges (-25º to 250 ºF). They’re suggested for use at moderate temperatures, light to heavy loads and moderate to high speeds.

Super-Refined Petroleum Lubricants

This type of lubricants may be usable at higher temperatures as compared to petroleum oils (-65 º to 350 ºF), but they still display the same excellent load carrying capacity.

Synthetic Lubricants

The esters, diesters and poly-a-olefins are among the most widely used synthetic lubricants. They may not have the film strength of a petroleum product, but they have a wide temperature range (-65º to 350 ºF) and are oxidation resistant.

Silicone Lubricants

Silicone products are typically used over a much wider temperature range (-100 º to 400 ºF), but they happen to not have the load carrying capacity of the petroleum types and other synthetics.

Perfluorinated Polyether (PFPE)

These types of oils and greases are widely used where stability at extremely high temperatures and/or chemical inertness is deemed necessary. This specialty lubricant possesses remarkable load carrying capacities. However, its inertness makes it less compatible to additives, and less corrosion resistant.
