High Torque Transmission and Load Distribution
Our Splined Couplings are engineered for strength, precision, and durability, ensuring efficient torque transfer between shafts in agricultural, industrial, and mechanical systems. Manufactured to the highest standards, our couplings provide secure, long-lasting connections for even the most demanding applications.
Types of Splined Couplings We Offer
We supply a complete range of splined connection solutions, including:
-
Splined Half Couplings
-
Splined Bars and Couplings
-
Chain Couplings
All our couplings are built from heat-treated steel UNI 16 CrNi4/P6, ensuring high resistance to wear, durability, and reliable power transmission.
Premium Half Couplings with Nitriding Treatment
Half couplings marked with (*) are manufactured from hardened and tempered steel UNI 38 NiCrMo4/Fb. These are subjected to a nitriding process to increase surface hardness and wear resistance, achieving a mechanical resistance rating of R = 95 to 105 Kg/mm². This ensures outstanding performance under heavy loads and extended service life.
