Application Spotlight: Wave Springs for Bearing Preload
What is bearing preload?
When assembling individual bearing components, the outer race, inner race, balls, and retainer all work together so that there is a controlled amount of internal clearance between the rings and balls. This radial play is necessary for proper operation, however, in most applications, it is also necessary to help reduce or eliminate the internal clearance to maintain...Read More>> |

Top 5 Reasons to Use a Crest-to-Crest Wave Spring
1. Reduced Work Height
In applications with tight space constraints, Crest-to-Crest® Wave Springs can take up to 50% space than a traditional coil spring. This space saving is made possible with the sinusoidal waves formed in the flat wire. This results in a more compact spring that takes less material to produce and can reduce the overall weight of the spring and assembly.
Figure 1. Crest-to-...Read More>> |
