Spring Washers

The single turn spring washer is characterized by its ability to provide elastic deformation in a small space, while having a high load capacity and fatigue life. It can effectively absorb shock and vibration, and play the role of buffering and damping. Read more...

Finger Springs are used to preload ball bearings and to reduce vibration in precision hard drive assemblies and other applications where light to medium loads are needed in a small space. Can be used at high speeds. Finger springs reduce noise and end play and do not increase in diameter during loading.

Contact points are equal to the number of fingers. Finger height is app... Read more...

We are often asked about securing bolted connections where parts have painted surfaces, something relevant to many applications and industries. The answer depends on the type of coating used and how it’s applied, though in general there are a few practical challenges to overcome. Read more...

Curved Springs may be used to reduce axial end play. They exert light thrust loads relative to their dimensions and have a nearly linear rate between 10% and 80% of available deflection (deflection should not exceed 80%). Curved Springs have two contact points and Outside Diameter expands under load. Curved Springs are often a solution in situations where Belleville Disc Springs would ha... Read more...

Gardner Curved Springs

Curved Disc Springs exert relatively light thrust loads and can be used to absorb axial endplay.

Gardner has significantly expanded its stock line of Curved Springs in both High Carbon Steel and 301 Stainless Steel.

Curved Springs have two contact points and Outside Diameter expands under load. Curved Springs are often a solution... Read more...

Ball Bearing Bellevilles are used to pre-load ball bearings to reduce noise and vibration, and are ideal for absorbing axial end play. These parts can be used to pre-load either the inner or outer ring of ball bearings, and are manufactured in sizes complimentary to a range of standard ball bearing sizes. Read more...

Different types of disc springs have different ranges of deflections as do different designs within categories. General deflection ranges, grouped by category, are as follows:

• Belleville Disc Springs: up to 75% of available deflection
• Curved Disc Springs: between 10% – 80% of avail. defl.
• Wave Disc Springs: between 20% – 80% of avail. def...

Disc springs are conically-shaped, washer-type components designed to be axially loaded. What makes disc springs unique is that based on the standardized calculations of DIN EN 16984 (formerly DIN 2092), the deflection for a given load is predictable and the minimum life cycle can be determined Read more...

SPIROL is pleased to announce that they now offer pre-stacked Disc Springs (greased or ungreased) in custom configurations packaged in shrink wrap with a perforated tab for ease of insertion into the application. Read more...
