Rigid coupling

When the application takes 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 suit shafts from 6mm up to 50mm in size as standard.
A good compression-type coupling or rigid coupling as it is sometimes termed has no versatility but can effectively be used for connecting two shafts to produce a long term joint. The solid coupling is generally designed to manage to transmitting the entire torque load capability of the shaft.
Ever-power stocks an array of solid (muff) style shaft coupling for fast easy shaft connection. Ideal for 6mm to 50mm diameter shafts, the anodised metal construction is made for arduous use. Merely release the clamp design design by detatching the four bolts, fit the coupling and then reapply the bolts to a set torque to achieve reliable shaft connection. Holding 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 keeping them firmly set up, rigid couplings help to maximize performance and boost the expected life of the machine. These rigid couplings can be found in two basic styles to fit the needs of different applications. Sleeve-style couplings will be the least expensive and easiest to use, whilst clamped or compression rigid couplings can be found in two parts and match jointly around the shafts to form a sleeve. Both types are available from Ever-power suiting shaft sizes from 6mm up to 50mm in size.
One and Two piece ABR rigid couplings – Two distinct designs are available. The main one and two piece series couplers have superior holding power and keep maintaining alignment. The single piece versions are given four clamping screws. The two piece split edition couplers could be installed and taken out without machine dis-assembly. Supplied with eight clamping screws, they offer reliable holding power and keep maintaining alignment.
Precision Rigid couplings are available as standard in aluminium alloy and stainless steel. For smaller shaft sizes the brand new SC series clamping technique that ensures the concentricity of the clamped shaft. Suited to shaft sizes from 3mm to 15mm diameter, including imperial and custom formats, make the brand new SC series perfect for applications where high torque and outstanding torsional stiffness are required.

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 jointly.
