helicoil , Iran
Rigid couplings are manufactured from forged C45 steel with heat treatment and 700 MPa tensile strength. These couplings are designed for shafts with diameters from 10 to 200 mm. Shaft bore tolerance precision follows ISO H7 standard for backlash-free connection. Gear couplings utilize helical gear teeth with a 20-degree pressure angle. This design accommodates angular misalignment up to 1.5 degrees. Torque transmission capacity ranges from 50 to 20,000 Newton meters. Disc couplings are produced from 316 stainless steel with 0.5 to 3 mm thickness. These couplings can absorb up to 95% of torsional vibrations.
Elastomeric coupling structures consist of two metal flanges and a rubber element. The rubber elements torsional hardness is adjustable between 40 to 90 Shore A. These couplings withstand operating temperatures from -30 to +120 degrees Celsius. Hydraulic couplings are filled with silicone oil of ISO VG 32 viscosity grade. They feature a shock absorption coefficient up to 250% of rated torque. Maximum rotational speed varies between 3,000 to 20,000 RPM across types. Hot-dip galvanized coating with 80-micron thickness guarantees corrosion resistance. Service life under nominal load exceeds 50,000 hours of continuous operation.You can order and buy helicoil from Iran by contacting us through whatsaap and email.

Key Considerations for Purchasing and Pricing Couplings
The price of a coupling depends on its type, size, material of construction, and manufacturing precision. Rigid couplings typically have a lower cost but require precise shaft alignment. Flexible couplings are more expensive due to their complex elastomeric or metallic components. The material grade, such as carbon steel, stainless steel, or special alloys, impacts both price and corrosion resistance. The maximum rated torque and maximum rotational speed must match the system requirements. The degree of misalignment compensation angular, parallel, axial is a key selection factor. Environmental conditions like temperature, humidity, and chemical exposure influence the choice of material and coupling type. Quality certifications ISO 9001 and industrial standards AGMA, DIN are criteria for ensuring quality. The maintenance cost and service life of high-quality couplings with available spare parts are more economical in the long run. Consulting with a mechanical engineer for precise selection based on dynamic and static calculations is recommended.
