What’s pin bush coupling?
Industrial Pin Bush Coupling
The function of a flexible coupling is to transmit torque from on shaft to another where limited mis alignment might occur and also to absorb shock loads.
We are among the prominent corporations engaged in providing Pinbush Coupling which has highly developed rubberized compounds for use in bushes to absorb shock, tensional vibrations and small misalignments. These couplings happen to be flexible in type and are generally of the cushioned travel type that is used for transmitting the torque through the best possible tensile steel bolts to the device input. Moreover, they are simple and small in construction which makes these capable of transmitting great torques at optimum speeds. These types of couplings generally permit travel in either direction and require neither lubrication, nor 
adjustment after fitting.

Ever-ability pin and bush coupling
Ever-power couplings consist of a couple of resilient BARREL Shaped bushes with pins & nuts and two flanged hubs of graded cast iron.
The special BARREL shaped bushes permit the MISALIGNMENT EVERYWHERE and present extra torsional flexibility when compared with plain bushes.
These couplings are ideal for general engineering application requiring reliable power transmitting even within conditions of shaft misalignments which are generally unavoidable.
Description
Ever-power couplings are being used when flexible compensating couplings in every applications requiring a reliable tranny of torque under harsh operating conditions. The conical chairs of the buffer pins facilitate mounting and guarantee maintenance-free procedure. The optimized condition of the barrelled buffers permits straightforward plug-in assembly and low circumferential backlash. Many type variants can be found, e. g. with brake disk, axial play limiting device, or brake electric motor couplings.

Pin & Bush Couplings
Simple and virtually indestructible, the pin and bush design and style is suitable for applications that involve safe practices, such as elevator drives or fire pumps. The fail-safe aspect of the design permits the coupling to become serviced at easy intervals, should the elastomer become damaged.
The elastomer elements decrease vibration and dampen impact loads, and accommodate misalignment up to 0.5 degrees. The initial bushing is definitely a neoprene elastomer with a graphite impregnated bronze sleeve. These are still available, in addition to a contemporary version of the concept: urethane bushings.
Ever-ability also manufactures many custom variations of the coupling including brake drum and shear pin type couplings.
Damping shaft coupling that can be utilised universally to compensate for shaft misalignment
Nominal torque range between TKN = 19 Nm up to 62,000 Nm with 23 sizes
Temperature range: from -50 °C to +100 °C

Robust and verified a million times
Due to their torsional overall flexibility, Ever-power couplings can move critical torsional vibrations away from the operating area of mechanical equipment in such a way that no unwanted effects on the travel train should be expected. Ever-electric power couplings are created from high-top quality cast iron. The flexible elements made of synthetic rubber (Buna-N) are available in different degrees of hardness for many applications. Steel pins and flexible components are designed so that no dress in occurs when they are properly fitted.

Did you know?
Original Ever-power elastomers ensure the optimal operation of your system. The flexible components of the Ever-electrical power coupling are at the mercy of compression. If the flexible elements are irreparably destroyed, the hub parts touch metal. This “emergency operation capability” is necessary, e.g., regarding fire pump drives.
