Flexible coupling: zero backlash disc coupling
SU, SX, DI series Lovejoy

Disc Couplings

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
