StepLess® Ear Clamps 117 & 167

StepLess® Ear Clamps 117 & 167 - Image 2

Narrow band: concentrates transmission of clamping force, less weight
Stepless over 360°: uniform compression or uniform surface pressure
Clamp ear: compensates for component tolerances, adjustable surface pressure
Dimple: increases clamping force, spring-effect compensates for changes in diameter due to thermal expansion
Burr-free strip edges: reduced risk of damage to parts being clamped

FEATURES

Material thickness

Stepless® Ear Clamps are produced in nominal widths and thicknesses. The selected material dimensions for a specific application are based on the stress required to obtain an adequate seal or load.

Clamp ear (closing element)

Using tools designed or endorsed by Oetiker, the clamp is closed by drawing together the lower radii of the “ear”. The maximum diameter reduction is proportionate to the open “ear” width (s).

The theoretical maximum reduction in diameter is given by the formula: Max. diameter reduction = Ear width (s) / π
