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

Ever-power 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 let the MISALIGNMENT IN ALL DIRECTIONS and give extra torsional flexibility as compared to plain bushes.
These couplings are ideal for general engineering application requiring reliable power transmission even underneath conditions of shaft misalignments which are generally unavoidable.
Description
Ever-power couplings are used while flexible compensating couplings in every applications requiring a trusted transmission of torque under harsh operating conditions. The conical seats of the buffer pins facilitate mounting and guarantee maintenance-free procedure. The optimized condition of the barrelled buffers permits basic plug-in assembly and low circumferential backlash. Many type variants are offered, electronic. g. with brake disk, axial play limiting device, or brake motor couplings.

Pin & Bush Couplings
Simple and almost indestructible, the pin and bush design is well suited for applications that involve security, such as for example elevator drives or perhaps fire pumps. The fail-safe facet of the design permits the coupling to be serviced at easy intervals, if the elastomer become damaged.
The elastomer elements decrease vibration and dampen impact loads, and accommodate misalignment up to 0.5 degrees. The original bushing is 
a neoprene elastomer with a graphite impregnated bronze sleeve. They are still available, in addition to a contemporary version of this concept: urethane bushings.
Ever-electric power also manufactures many customized 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 from TKN = 19 Nm up to 62,000 Nm with 23 sizes
Temperature range: from -50 °C to +100 °C
Robust and confirmed a million times
Due to their torsional versatility, Ever-power couplings can move critical torsional vibrations away from the operating region of mechanical equipment so that no negative effects on the drive train are to be expected. Ever-electrical power couplings are made from high-quality cast iron. The versatile elements made of synthetic rubber (Buna-N) can be found in different levels of hardness for many applications. Metal pins and flexible components are designed to ensure that no put on occurs if they are properly fitted.

Original Ever-power elastomers ensure the perfect operation of one’s body. The flexible factors of the Ever-vitality coupling are at the mercy of compression. If the flexible elements are irreparably ruined, the hub parts come into contact with metal. This “emergency procedure capability” is necessary, e.g., in the case of fire pump drives.
