Rigid coupling

When the application takes a direct and solid shaft connection and that shaft misalignments during operation are minimal, then your 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 as 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 normally designed to be capable of transmitting the entire torque load capacity of the shaft.
Ever-power stocks an array of solid (muff) style shaft coupling for fast easy shaft connection. Ideal for 6mm to 50mm size shafts, the anodised steel construction is made for arduous use. Basically release the clamp style design by removing the four bolts, suit the coupling and then reapply the bolts to a fixed torque to accomplish reliable shaft connection. Keeping tight tolerances to the concentricity on the bore, makes the Ever-power rigid coupling an ideal emergency fix or prototype connection.
By precisely aligning both shafts and keeping them firmly in place, rigid couplings help maximize performance and raise the expected existence of the device. These rigid couplings are available in two basic styles to fit the needs 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 match together around the shafts to create a sleeve. Both types are available from Ever-power suiting shaft sizes from 6mm up to 50mm in size.
One particular and Two piece ABR rigid couplings – Two distinct styles are available. The main one and two piece series couplers have superior holding power and keep maintaining alignment. The one piece versions are given four coupling China clamping screws. Both piece split version couplers can be installed and taken out 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. For smaller shaft sizes the new SC series clamping method that ensures the concentricity of the clamped shaft. Suitable for shaft sizes from 3mm to 15mm diameter, including imperial and custom formats, make the new SC series well suited 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 assistance in heavily loaded shafts. These couplings are bored accurate to shaft size, and the halves are separated through the boring operation to allow for clamping when the halves are drawn together.
