When the application requires a direct and solid shaft connection and that shaft misalignments during procedure are minimal, then the ABR solid or rigid type couplings may be used. To match 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 versatility but can effectively be used to connect two shafts to make a long term joint. The solid coupling is normally designed to be capable of transmitting the full torque load capacity of the shaft.
Ever-power stocks a wide variety of solid (muff) design shaft coupling for fast easy shaft connection. Perfect for 6mm to 50mm diameter shafts, the anodised steel construction is designed for arduous use. Simply release the clamp style design by detatching the four bolts, match the coupling and then reapply the bolts to a set torque to attain reliable shaft connection. Keeping tight tolerances to the concentricity on the bore, makes the Ever-power rigid coupling an ideal emergency repair or prototype connection.
By precisely aligning both shafts and holding them firmly in place, rigid couplings help maximize performance and raise the expected life of the device. These rigid couplings are available in two basic styles to fit the requires of different applications. Sleeve-style couplings will be the most affordable and easiest to use, whilst clamped or compression rigid couplings come in two parts and suit together 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.
1 and Two piece ABR rigid couplings – Two distinct designs are available. The one and two piece series couplers have got superior holding power and keep maintaining alignment. The single piece versions are supplied with four clamping screws. Both piece split version couplers could be installed and removed without machine dis-assembly. Given eight clamping screws, they provide reliable holding power and maintain alignment.
Precision Rigid couplings can be found as regular in aluminium alloy and stainless steel. For smaller shaft sizes the brand new SC series clamping method that ensures the concentricity of the clamped shaft. Suitable for shaft sizes from 3mm to 15mm size, including imperial and custom made formats, make the brand new SC series ideal for applications where high torque and exceptional torsional stiffness are needed.

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 true to shaft size, and the halves are separated through the boring coupling China operation to allow for clamping when the halves are drawn collectively.
