SmalleyCorrugated springs SSR
Single-turn corrugated springs, also known as bearing preload compression springs, eliminate play and reduce bearing noise, as the constant light or medium pressure they apply eliminates play between ball bearings and inner and outer races.
Similarly, preloading reduces vibration and premature bearing wear through less impact and friction.
Corrugated springs offer many advantages over stamped products.
Firstly, they allow radial expansion, or an increase in diameter without the locking or snagging normally associated with stamped corrugated washers.
In addition to this main advantage, they are also more precise, with a stiffness tolerance 50% greater than that of stamped parts.
Manufactured from pre-tempered materials, they also present no risk of deformation during any hardening heat treatment. By comparison, the manufacturing processes for corrugated stamped washers can lead to problems such as fatigue cracking and less precise, less even loading between springs.
Corrugated springs are available in two types: Gap and Overlap.
The Gap type is open to maintain free space between the ends, while the Overlap type has overlapping ends. As a result, the ends can move in an arc as the outer diameter of the spring increases during compression.
They are designed to match the most common metric bearing sizes. They are available in carbon steel or 17-7 stainless steel.
SSR corrugated spring stiffness is measured in lb/in.
1 pound = 4.448N
1 inch = 25.4 mm
As the spring is compressed, the external and internal diameter increase until the external diameter enters into contact with the bore.
Wave springs are available in carbon steel and stainless steel, in diameters from 1/2” to 16”.
