When the application requires a direct and solid shaft connection and that  shaft misalignments during operation are minimal, then the ABR solid or rigid type couplings can be used. To suit shafts from 6mm up to 50mm in diameter as standard.

A solid compression-type coupling or rigid coupling as it is sometimes termed has no flexibility but can effectively be used to connect two shafts to make a permanent joint. The solid coupling is usually designed to be capable of transmitting the full torque load capacity of the shaft.

By precisely aligning the two shafts and holding them firmly in place, rigid couplings help to maximize performance and increase the expected life of the machine. These rigid couplings are available in two basic designs to fit the needs of different applications. Sleeve-style couplings are the most affordable and easiest to use, whilst clamped or compression rigid couplings come in two parts and fit together around the shafts to form a sleeve. Both types are available from Abssac  suiting shaft sizes from 6mm up to 50mm in diameter.

One and Two piece ABR rigid couplings - Two distinct designs are available. The one and two piece series couplers have superior holding power and maintain alignment. The single piece versions are supplied with four clamping screws. The two piece split version couplers can be installed and removed without machine dis-assembly. Supplied with eight clamping screws, they provide reliable holding power and maintain alignment.

Miniature Precision Solid Couplings

Miniature Precision Solid CouplingsPrecision Rigid couplings are available as standard in aluminium alloy and  stainless steel.  For smaller shaft sizes the new SC series  clamping method that ensures the concentricity of the clamped shaft. Suited to  shaft sizes from 3mm to 15mm diameter, including imperial and custom formats, make the new SC series ideal for applications where high torque and exceptional torsional stiffness are required.

  • Exceptional torsional stiffness
  • High torque capacity
  • Metric and Imperial bore formats
  • Integral clamp shaft attachment
