What’s pin bush coupling?
Industrial Pin Bush Coupling
The function of a flexible coupling is to transmit torque from on shaft to some other in cases where limited mis alignment might occur and to absorb shock loads.
We are one of the prominent institutions engaged in providing Pinbush Coupling which has highly developed rubber substances for use in bushes to absorb shock, tensional vibrations and slight misalignments. These couplings are flexible in type and are generally of the cushioned travel type that is employed for transmitting the torque through maximum tensile metal bolts to the device input. Moreover, they are simple and compact in construction that makes these capable of transmitting high torques at optimum speeds. These kind of couplings generally permit travel in either path and require neither lubrication, nor adjustment after fitting.

Ever-electrical power pin and bush coupling
Ever-power couplings contain 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 as compared to plain bushes.
These couplings are well suited for general engineering application requiring reliable power transmitting even within conditions of shaft misalignments which are often unavoidable.
Description
Ever-power couplings are being used because flexible compensating couplings in all applications requiring a reliable tranny of torque under harsh operating circumstances. The conical seats of the buffer pins facilitate installation and guarantee maintenance-free procedure. The optimized form of the barrelled buffers permits simple plug-in assembly and low circumferential backlash. Many type variants can be found, e. g. with brake disk, axial play limiting unit, or brake motor couplings.

Benefits of the product
Flexible fail-safe pin and bush coupling for moderate up to high torques
Compact design; low weights and mass moments of inertia
Independent of way of rotation (ideal for reversing operation)
Suitable for plug-in assembly (blind assembly, bell housing installation)
Torque range of the typical series between 200 Nm and 1,300,000 Nm

Pin & Bush Couplings
Simple and virtually indestructible, the pin and bush style is perfect for applications that involve basic safety, such as elevator drives or perhaps fire pumps. The fail-safe aspect of the design permits the coupling to end up being serviced at hassle-free intervals, should the elastomer become damaged.
The elastomer elements lessen vibration and dampen impact loads, and also accommodate misalignment up to 0.5 degrees. The original bushing is certainly a neoprene elastomer with a graphite impregnated bronze sleeve. They are still available, as well as a contemporary version of the concept: urethane bushings.
Ever-power also manufactures many custom variations of the coupling including brake drum and shear pin type couplings.
Damping shaft coupling that works extremely well 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 
tested a million times
Due to their torsional overall flexibility, Ever-power couplings can move critical torsional vibrations from the operating region of mechanical equipment in such a way that no negative effects on the travel train are to be expected. Ever-vitality couplings are constructed with high-top quality cast iron. The adaptable elements manufactured from synthetic rubber (Buna-N) are available in different degrees of hardness for most applications. Steel pins and flexible factors are designed in order that no use occurs when they are properly fitted.

Did you know?
Original Ever-power elastomers ensure the perfect operation of one’s body. The flexible components of the Ever-vitality coupling are subject to compression. If the flexible elements are irreparably harmed, the hub parts touch metal. This “emergency operation capability” is necessary, e.g., regarding fire pump drives.
