    Using advanced design techniques, implementation of Finite Element Analysis, and extensive testing of materials, Lovejoy 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 Lovejoy disc coupling products.

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

    Lovejoy disc couplings utilize unitized disc packs with 4, 6 or 8 bolt designs. While the 8 bolt design can transmit greater torque than the 6 or 4 bolt design, it is not able to accommodate as much angular misalignment.
