Part Number 68514413923, UF Type / RRU Drop Out


UF Type - Flange-to-Flange
    This coupling is actually the center dropout section of the RRU Type, but it can be purchased separately for direct flange-to-flange mounting of the driving unit to the driven. The UF Type coupling compensates for high misalignment to protect connected equipment, yet it is also well-suited for applications which require negligible backlash or windup and reliability under high temperature conditions. Stock flange sizes are shown in the Dimensional Data table below, but other sizes can be provided to meet special mounting requirements.
    This flange-to-flange type is designed to connect flange mounted equipment to another flange while compensating for misalignment. It is also the center drop out section of the RRU Type.
    Note: The UF Type Drop Out does not come with assembly hardware. Assembly hardware must be purchased separately.

Coupling Design
Flexible Spring Type Coupling with Exclusive Triple Wound Spring Design
    The Uniflex Coupling is an all steel, single piece coupling that solves a variety of application concerns including: high misalignment, space limitations, high temperature, and exceptionally low backlash/windup. The unique flexing center of the Uniflex consists of three opposingly wound square wire springs for forward or reverse operation. Two steel hubs are then brazed to the steel spring pack to create a durable one-piece flexible coupling.




Notes

Notes 
  • OAL Tolerance + .19 inch.
