Tradelink Services offers Spring Couplings with Speeds up to 20,000 rpm. Tradelink Services supplies various mechanical power transmission engineering components. The Spring Couplings with Speeds up to 20,000 rpm is a rotation - elastic transmission element that consists of a spring assembly with 3 layers, with each layer comprising 3 single springs with square cross section. This spring assembly is linked by hubs / flanges - according to standard sizes. Compact with high torque transmission, spring couplings offer lower inertia. Higher speeds are also possible. Standard models [completely in steel] can be used between -40 to +100 Degree C. Special couplings cater to temperature up to +300 Degree C. The torque capability ranges from 2.5Nm to 900 Nm, speeds up to 20,000 rpm and bore range from 4mm to 75mm can be supplied in Stainless Steel, also.
