Coneflex Couplings have a unique concave design principle which provides 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. Stocked on many popular bore sizes and application ratings. 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. Click here for quote
