SUNGIL SRG / SRGL Rigid Coupling, Aluminum (OD 16-53 mm)

SUNGIL SRG / SRGL Rigid Coupling, Aluminum (OD 16-53 mm)

One-piece aluminum rigid coupling with no backlash or loss of motion. Shafts must be aligned accurately as it does not absorb misalignment; SRGL is the long side-clamp type.

Key features

  • One-piece body, zero backlash and no lost motion
  • Very high torsional stiffness for precision positioning
  • Set-screw (SRG), side-clamp (SRG-C) and long side-clamp (SRGL-C)
  • Hub split (CW) available on side-clamp types
  • Keyway machining available

Specifications

Body material High strength aluminum alloy, anodized
Screws SCM435, black oxide
Clamping Set-screw / side-clamp (C) / hub split (CW)
Misalignment Not absorbed; align shafts accurately
Shaft tolerance h7 recommended
