The Different Types of Thin Section Bearings

The Different Types of Thin Section Bearings

March 25, 2019

While small in width, thin section bearings can come in a variety of styles. Each type of thin section bearing boasts various advantages and disadvantages, which makes it important to know which style is best suited for your needs. To help, here’s a quick breakdown of the different styles of thin section bearings and the types of jobs they’re meant to handle.

Thin Section Radial Ball Bearings

As the name would suggest, thin section radial ball bearings are used for demanding applications with predominantly radial loads. These bearings come in multiple styles and cross sections, such as open and sealed variants. While they’re best suited for radial loads, they can also accept very minimal axial, reversing, and moment loads.

Thin Section Angular Contact Bearings

While radial thin section bearings are designed to handle radial loads, angular contact thin section bearings are best served for higher thrust and axial loads. However, they can also accept some radial and combined loads. Angular contact thin section bearings are commonly paired depending on the needs of an application, which can result in any of the following duplex pairs:

  • Back-to-back duplex pair
  • Face-to-face duplex pair
  • Tandem duplex pair

Thin Section Four-Point Contact Bearings

Four-point contact thin section bearings feature a special raceway – also known as a “gothic archway” – that creates four points of contact. This design allows these bearings to do an excellent job of handling moment and reversing loads, plus additional thrust loads. However, four-point contact thin section bearings are not recommended for with in applications with radial and combined loads.

Build Your Own Custom Thin Section Bearing

While you may know your application inside and out, it can be difficult to find just the right bearing solution for your needs – and that’s if what you need is even readily available. Instead, design your own custom parts with our online thin section bearing builder.

All you need to do is plug in certain criteria like bearing type, part quantity, and other details that you need for your parts. Once you submit your customized bearing, SSB will submit your request and send you a quote.

If you’re not sure exactly what you need for your applications, SSB can still help you find the right parts. Contact us today to talk to one of our experts about your bearing needs and we can get to work on a solution.

Warning: Using the Wrong Lubrication Could Destroy Your Bearings

Warning: Using the Wrong Lubrication Could Destroy Your Bearings

June 30, 2017

A bad choice of lubrication can even make the best parts go bad. How? Incorrect lubrication can lead to serious issues like overheating and excessive wear, both of which can lead to bearing failure. Not only can these problems force you to repair each affected part, it can lead to additional costs related to downtime and repair. Fortunately, there are lubrication best practices for bearings that can help you ensure that your applications aren't negatively impacted.

How to Prevent the Use of the Wrong Bearing Lubricant

The first thing you'll want to do is to make sure you are using the right type and amount of lubricant for your specific bearings. It may seem obvious, but a simple misreading and misuse will lead to a lot of trouble in the future, especially for when you have to relubricate bearings in the future.

Of course, it's not always obvious which lubricant is the correct for for your parts. You'll also need to consider how much lubrication is necessary. Most fill rates sit between 25 and 35 percent of the available space in the bearing, but some parts may differ. Not sure where to start? Here are some common lubricants and their traditional applications.

Types of Bearing Lubrication

General grease (NLGI #2)

The most common lubricant for bearings.Standard bearings come with Polyrex EX grease. Greases are designed for a wide temperature range, which makes them a good option for motor applications.

Synthetic grease

A wide variety of these greases fit application parameters, including low torque requirements or extreme temperatures. These greases are a natural fit for aerospace applications.

Solid lubricants & oils

These options give you a way of carrying oils while releasing the proper amount over time. Solid lubricants are usable in many wash down applications. In addition, a variety of solid lubricants are FDA rated H1 or H2, making them great for food and beverage applications.

Graphite (dry or solid) lubricant

Graphite offers lubrication at higher temperatures than typical liquid and oil-based options. It's also ideal for extreme low torque considerations, such as high speed applications.

Specialized plating

Features the FENCR Process, in which a diffused layer of carbon rich iron nitride is applied to the bearings so that the product will not chip or spall. This is ideal for product that needs to be corrosion resistant, such as those in extreme moisture environments. Specialized plating is not FDA rated.

While there are many lubrication options you can choose from, it may be difficult to select the right one for your applications. If you aren't sure which lubrication is the best choice, the bearing experts at Slim Section Bearings can can help you narrow down your options. Contact SSB today to talk to our experts about your bearing needs.
