Eliminates the need for lubrication and coupling maintenance
Coupling can be inspected without disassembly
Condition of disc packs can be inspected with a strobe light while the machine is running
(Note: It is not recommended that couplings be operated without coupling guards.)
Easy to assess equipment misalignment
Torsionally rigid without any backlash
No wearing parts
Resistance to harsh environments
Long life when properly sized and aligned
High power density (higher torque for a given outside diameter)
Lovejoy supports the API-610 Standard up to 3,800 RPM
Unitized disc packs ensure repeatability necessary for meeting the balance and piloting requirements as mandated by API-610
ATEX Certified for SU, SX, DI, SXC, SXCS, SXCST, DIR, DILR, DIRA and DIRLA product lines
The disc pack can accomodate 1/2 ° to 1-1 / 2 ° of angular misalignment, and is used in all disc couplings products.
Disc packs are manufactured using high grade stainless steel (AISI-301), ensuring high strength, high endurance to fatigue, and resistance to most environmental conditions. 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. Couplings can also be fitted with overload bushings to protect the disc pack during momentary torsional overloads.
