When the application takes a direct and solid shaft connection and that shaft misalignments during operation are minimal, then the ABR solid or rigid type couplings may be used. To suit shafts from 6mm up to 50mm in size as standard.
A solid compression-type coupling or rigid coupling since it is sometimes termed has no flexibility but can effectively be used for connecting two shafts to make a permanent joint. The solid coupling is usually designed to be capable of transmitting the entire torque load capability of the shaft.
Ever-power stocks a wide selection of solid (muff) design shaft coupling for fast easy shaft connection. Perfect for 6mm to 50mm diameter shafts, the anodised metal construction is made for arduous use. Just release the clamp design design by detatching the four bolts, suit the coupling and reapply the bolts to a set torque to attain reliable shaft connection. Holding tight tolerances to the concentricity on the bore, makes the Ever-power rigid coupling a perfect emergency fix or prototype connection.
By precisely aligning the two shafts and keeping them firmly set up, rigid couplings help to maximize performance and raise the expected lifestyle of the machine. These rigid couplings are available in two basic styles to fit the desires of different applications. Sleeve-style couplings are the most affordable and easiest to make use of, whilst clamped or compression rigid couplings come in two parts and match jointly around the shafts to form a sleeve. Both types can be found from Ever-power suiting shaft sizes from 6mm up to 50mm in diameter.
A single and Two piece ABR rigid couplings – Two distinct designs are available. The main one and two piece series couplers have got superior holding power and keep maintaining alignment. The single piece versions are given four clamping screws. The two piece split edition couplers can be installed and removed without machine dis-assembly. Supplied with eight clamping screws, they provide dependable holding power and maintain alignment.
Precision Rigid couplings are available as coupling China standard in aluminium alloy and stainless steel. For smaller sized shaft sizes the brand new SC series clamping method that ensures the concentricity of the clamped shaft. Suited to shaft sizes from 3mm to 15mm size, including imperial and custom formats, make the new SC series perfect for applications where high torque and excellent torsional stiffness are required.

In the event that you require further complex information, please usually do not hesitate to contact our sales engineers who’ll be more than pleased to help you with your selection.

Ever-power’s Rigid couplings are ribbed-type compression couplings that are recommended for emergency and regular program on heavily loaded shafts. These couplings are bored accurate to shaft size, and the halves are separated during the boring operation to permit for clamping when the halves are drawn together.
