Product description

The wave spring is a precision flat wire compression spring, which is suitable for installation in parts where other springs cannot meet the requirements and the space is limited. It can save 50% of space compared with general spiral springs.

Wave spring is also called wave spring. It is an elastic element with several peaks and valleys on a metal thin ring. It is usually used in occasions where the load and deformation are small and axial prestress needs to be applied.

Wave springs are particularly suitable for applications that require weight reduction and are limited by smaller installation spaces. Typical application areas include: aerospace, precision machinery, hydraulic seals, and high-end motors.

Preloading a Bearing: What is Preloading, How to Preload, Why Should You Preload a Bearing?

Content provided by Smalley

What do we mean when we say “preload”?

A bearing is designed to move freely and has multiple moving parts that work together as one unit. Tolerance stack up from both manufacturing and assembly can quickly cause issues.

This is where preloading a bearing comes in. Preloading a bearing involves providing a sustained axial load to the bearing.

How Do I Preload a Bearing? Are There Different Types of Preload?

There are two main methods to preload a bearing. The first is solid preload, which is achieved by holding inner and outer races in place with a locking mechanism.

The more common, simpler, and less expensive method is spring preload, which is achieved by using a spring to apply a constant axial load on one side. A Smalley single-turn wave spring provides the necessary preload force between the inner or outer races while also compensating for any tolerance stack-ups or thermal misalignments. Play is reduced both axially and radially, as depicted in the image below.

So what’s the big deal, why do we preload bearings?

Controlling play is necessary to maintain bearing functionality and longevity. Preloading a bearing provides constant contact between the bearing type (ball, needle, etc.) and bearing races. The sustained load provided by the spring eliminates axial and radial play, among other benefits. The overall goal of preloading is to prolong bearing life, and therefore, your application.

Advantages of Spring Preload

Properly preloading a bearing will prolong the bearing’s life. Using a spring for preload is critical for high-precision or high-speed applications, as it essentially eliminates the need for holding tighter tolerances and helps withstand high operating speeds.

1. Axial and radial play control
   Ball complement and bearing races mate reliably and take up dimensional variation.
    
2. Less wear on the bearing
   Greater load sharing between bearings due to wave design. 
    
3. Vibration and noise reduction
   Quieter assemblies, even in high-vibration applications.
    
4. Eliminate ball skidding
   Constant force is applied for smooth movement.
    
5. Precise shaft positioning
   Wave spring keeps shaft centered for optimal centrifugal distribution.

What type of spring should I use to preload a bearing?

Every application is unique, which makes selecting the proper wave spring very important.

It’s important to consider overall tolerances, as placing too much preload on the bearing can reduce longevity, while too little can cause higher noise output in high-vibration systems.

Smalley’s bearing preload wave spring SSB series is carefully designed with the application in mind. The two types of single-turn wave springs we offer are gap and overlap.

While the gap type splits its ends, the overlap type overlaps its ends. Both end configurations can move freely around the circumference as the spring compresses, providing an advantage over traditional wave washers. Wave washers can bind, or become rigid, if pushed into the cavity too much, causing the spring load to become unpredictable.

We have over 300+ standard parts available in carbon steel and stainless steel to match popular bearing sizes. Find your size by checking out the bearing cross-reference table. A Nested spring is another type of spring we offer that can accommodate higher preload requirements. A three-turn Nested spring is pictured in the bearing application below.
