MBC - Metric Clamp Bellows Coupling

Metric Clamp Bellows Coupling

Features

  • High torque
  • Balanced for high RPM
  • Low Inertia
  • No maintenance
  • High torsional stiffness
  • Constant velocity
  • Long life
  • Zero backlash
  • Bore tolerance: +.025mm/-.000mm
  • Maximum speed: 10,000 RPM
  • Temperature Range: -40°F to 200°F

Notes

  • Aluminum hubs are standard
  • Hubs also available in stainless steel
  • Inch and metric hubs (set screw or clamp) can be combined into a single coupling as long as they have the same outside diameter (OD)

Note 1 Static torque ratings are at maximum misalignment. To obtain dynamic rating, static ratings should be divided by 2 for non-reversing applications and by 4 for reversing applications.
Note 2 Performance ratings are for guidance only. The user must determine suitability for a particular application.
Note 3 Our standard couplings are supplied with black anodized aluminum hubs. Stainless steel hubs are available upon request.
Note 4 Torque ratings for the couplings are based on the physical limitations/failure point of the metal bellows. Under normal/typical conditions the hubs are capable of holding up to the rated torque of the metal bellows. In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the rated torque of the metal bellows. Keyways are available to provide additional torque capacity in the shaft/hub connection when required. Please consult technical support for more assistance.
