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 to absorb shock loads.
We are one of the prominent corporations engaged in providing Pinbush Coupling that has highly developed rubber substances for use in bushes to absorb shock, tensional vibrations and small misalignments. These couplings will be flexible in type and tend to be of the cushioned drive type that can be used for transmitting the torque through maximum tensile metal bolts to the machine input. Moreover, these are simple and compact in construction which makes these capable of transmitting large torques at maximum speeds. These types of couplings generally permit travel in either route and require neither lubrication, nor adjustment after fitting.
Pin and Bush Couplings
Progressive torsion spring properties due to primarily pressurised bushings
Fail-safe in case of the failing of the bushings
Easy replacement of bushings without disassembly of the coupling halves
Maintenance free, no lubrication necessary
Declaration of conformity relative to ATEX 2014/34/EU possible

Ever-electrical 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 permit the MISALIGNMENT EVERYWHERE and give extra torsional flexibility as compared to plain bushes.
These couplings are suitable for general engineering application requiring reliable power tranny even underneath conditions of shaft misalignments which are generally unavoidable.
Ever-power couplings are used seeing that flexible compensating couplings in every applications requiring a reliable transmission of torque under harsh operating conditions. The conical chairs of the buffer pins facilitate mounting and guarantee maintenance-free procedure. The optimized form of the barrelled buffers allows straightforward 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 virtually indestructible, the pin and bush style is ideal for applications that involve protection, such as elevator drives or fire pumps. The fail-safe facet 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, as well as accommodate misalignment up to 0.5 degrees. The initial bushing can be a neoprene elastomer with a graphite impregnated bronze sleeve. They are still available, as well as a contemporary version of this concept: urethane bushings.
Ever-ability also manufactures many customized variations of the coupling including brake drum and shear pin type couplings.
Damping shaft coupling that can be utilized 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 proven a million times
Due to their torsional overall flexibility, Ever-power couplings can move critical torsional vibrations away from the operating location of mechanical equipment in such a way that no negative effects on the drive train are to be expected. Ever-electrical power couplings are made of high-top quality cast iron. The flexible elements manufactured from synthetic rubber (Buna-N) can be found in different degrees of hardness for many applications. Metallic pins and flexible elements are designed so that no use occurs if they are properly fitted.

Did you know?
Original Ever-power elastomers ensure the optimal operation of one’s body. The flexible factors of the Ever-ability coupling are at the mercy of compression. If the flexible elements are irreparably broken, the hub parts touch metal. This “emergency procedure capability” is necessary, e.g., in the case of fire pump drives.
