What is pin bush coupling?
Industrial Pin Bush Coupling
The function of a flexible coupling is to transmit torque from on shaft to some other where limited mis alignment might occur and also to absorb shock loads.
We are one of the prominent corporations engaged in providing Pinbush Coupling which has highly developed rubberized compounds for use in bushes to absorb shock, tensional vibrations and slight misalignments. These couplings will be flexible in type and are generally of the cushioned drive type that can be used for transmitting the torque through the best tensile steel bolts to the machine input. Moreover, they are simple and small in construction that makes these capable of transmitting huge torques at maximum speeds. These types of couplings generally permit drive in either path and need neither lubrication, nor adjustment after fitting.

Ever-electricity pin and bush coupling
Ever-power couplings contain a set 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 in comparison with plain bushes.
These couplings are well suited for standard engineering application requiring reliable power transmitting even beneath conditions of shaft misalignments which are often unavoidable.
Description
Ever-power couplings are being used as flexible compensating couplings in all applications requiring a reliable transmitting of torque under harsh operating circumstances. The conical chairs of the buffer pins facilitate installation and guarantee maintenance-free operation. The optimized form of the barrelled buffers allows straightforward plug-in assembly and low circumferential backlash. A large number of type variants can be found, e. g. with brake disk, axial play limiting unit, or brake electric motor couplings.

Pin & Bush Couplings
Simple and virtually indestructible, the pin and bush design and style is perfect for applications that involve safe practices, such as elevator drives or fire pumps. The fail-safe aspect of the design allows the coupling to end up being serviced at comfortable intervals, should the elastomer become damaged.
The elastomer elements reduce vibration and dampen impact loads, and also accommodate misalignment up to 0.5 degrees. The initial bushing can be a neoprene elastomer with a graphite impregnated bronze sleeve. These are still available, as well as a contemporary version of the concept: urethane bushings.
Ever-electrical power also manufactures many custom variations of this coupling including brake drum and shear pin type couplings.
Damping shaft coupling that can be utilized universally to pay for shaft misalignment
Nominal torque range from TKN = 19 Nm up to 62,000 Nm with 23 sizes
Temperature range: from -50 °C to +100 °C
Robust and proven a million times
Due to their torsional flexibility, Ever-power couplings can maneuver critical torsional vibrations from the operating spot of mechanical equipment in such a way that no unwanted effects on the travel train should be expected. Ever-power couplings are made of high-top quality cast iron. The versatile elements manufactured from synthetic rubber (Buna-N) can be found in different degrees of hardness for most applications. Steel pins and flexible components are designed in order that no wear 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-electric power coupling are subject to compression. If the versatile elements are irreparably harmed, the hub parts come into contact with metal. This “emergency operation capability” is required, e.g., regarding fire pump drives.
