Kalsi Seals

In support of the equipment design activities of our rotary shaft seal customers, Kalsi engineering offers an O-ring gland design calculator and a coil spring design calculator. These calculators were originally developed to support our own design activities.

Design Software

O-Ring Analyst™ Rev. 2.1a (Download Here)

Our O-Ring Analyst software generates “standard” static O-Ring gland dimensions, and presents them in an editable format so the user can optimize them for function, manufacturability, ease of assembly, etc. Compression results take into account cross-sectional reduction due to installation stretch. Compression and extrusion gap results are given for nominal and worst case sizes, and for concentric and eccentric conditions. Nominal running friction is also estimated.

Helical Spring Rev. 7.0 (Download Here)

Our Helical Spring software is used to design round wire helical compression springs. The software consists of two modules. The “Auto Generator” module generates a series of spring geometries covering an index of 4 to 16 that are based on a user-defined solid load and stress. The user can then refine the most appropriate diameter spring using the “Spring Design” module, which presents results in an editable format.

Viscocity Calculator Rev. 0 (Download Here)

Our Viscosity-Calculator software is used to predict the kinematic viscosity of an ISO lubricant at specified temperatures. The viscosity predictions are based on Walther’s equation which is the basis for ASTM D341 charts.
