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 match shafts from 6mm up to 50mm in diameter as standard.
A good compression-type coupling or rigid coupling since it is occasionally termed has no versatility but can effectively be used to connect two shafts to produce a long lasting joint. The solid coupling is normally designed to be capable of transmitting the full torque load capability of the shaft.
Ever-power stocks an array of solid (muff) design shaft coupling for fast easy shaft connection. Perfect for 6mm to 50mm diameter shafts, the anodised steel construction is made for arduous use. Basically release the clamp style design by coupling China removing the four bolts, match the coupling and reapply the bolts to a fixed torque to achieve 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 holding them firmly in place, rigid couplings help maximize performance and boost the expected lifestyle of the machine. These rigid couplings can be found in two basic styles to fit the demands of different applications. Sleeve-style couplings are the least expensive and easiest to make use of, whilst clamped or compression rigid couplings come in two parts and suit jointly around the shafts to create a sleeve. Both types can be found from Ever-power suiting shaft sizes from 6mm up to 50mm in diameter.
One and Two piece ABR rigid couplings – Two distinct styles are available. The main 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 could be installed and eliminated without machine dis-assembly. Given eight clamping screws, they provide dependable holding power and keep maintaining alignment.
Precision Rigid couplings are available as regular 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 size, including imperial and custom formats, make the new SC series ideal for applications where high torque and excellent torsional stiffness are required.

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