Coneflex Couplings

Coneflex Couplings have a unique concal design principle which provide maximum bearing area and more evenly distributed loads when operating in misaligned conditions.

Pressure surfaces of jaws are accurately die cast to form a cone segment.

Coupling jaws and inserts maintain their relative position even under misaligned conditions. This allows uniform compression that results in longer life.

Oil resistant high grade synthetic rubber inserts have similar pressure surfaces that conform to the die cast jaws. This provides an equalized and cushioned transfer of power.

Coupling halves are manufactured from high tensile zinc so rust problems are eliminated.

Coupling Halves

All Coneflex Coupling Halves are furnished with standard keyways and setscrews. Non standard Bore Sizes and keyways are available upon request. Couplings No. 1, No. 2, & No. 4 are available by Quotation.

 To Select the correct Coneflex coupling:

1. Determine the horsepower rating of the supplying motor or engine and it’s maximum rpm.

2. Determine the applications service factor number from the Service Factor Chart.

3. Multiply the supplied horsepower by the service factor number. The result is the application rating number.

4. From the Applications Ratings Chart, select the coupling that has a higher rating number than that calculated in step 3 above, at the specified rpm.
