Disc Couplings


EP takes great pride in being able to offer a wide variety of superior disc coupling products in models designed to meet the application needs of today’s worldwide power transmission market.

Using advanced design techniques, implementation of Finite Element Analysis, and extensive testing of materials, EP has developed an innovative disc pack profile design revolutionary to traditional disc pack designs found in the market. This disc pack can accommodate 1/2° to 1-1/2° of angular misalignment, and is used in all EP disc coupling products.

EP disc packs are manufactured using high grade stainless steel (AISI-301), ensuring high strength, high endurance to fatigue, and resistance to most environmental conditions.

EP disc couplings utilize unitized disc packs with 4, 6 or 8 bolt designs. As the 8 bolt style can transmit better torque compared to the 6 or 4 bolt style, it is not in a position to accommodate as very much angular misalignment.

EP couplings may also be fitted with overload bushings to safeguard the disk pack during momentary torsional overloads.
