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 organizations engaged in providing Pinbush Coupling which has highly developed rubber compounds for use in bushes to absorb shock, tensional vibrations and slight 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 ideal tensile steel bolts to the device input. Moreover, they are simple and compact in construction that makes these capable of transmitting substantial torques at optimum speeds. These kind of couplings generally permit drive in either direction and require neither lubrication, nor adjustment after fitting.

Ever-vitality 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 IN ALL DIRECTIONS and give extra torsional flexibility when compared with plain bushes.
These couplings are well suited for standard engineering application requiring reliable power tranny even under 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 tranny of torque under harsh operating conditions. The conical seats of the buffer pins facilitate installation and guarantee maintenance-free procedure. The optimized form of the barrelled buffers enables straightforward plug-in assembly and low circumferential backlash. Many type variants can be found, e. g. with 
brake disk, axial play limiting product, or brake motor couplings.

Pin & Bush Couplings
Simple and virtually indestructible, the pin and bush design and style is well suited for applications that involve protection, such as elevator drives or perhaps fire pumps. The fail-safe facet of the design permits the coupling to become serviced at hassle-free intervals, should the elastomer become damaged.
The elastomer elements reduce vibration and dampen impact loads, along with accommodate misalignment up to 0.5 degrees. The original bushing is usually a neoprene elastomer with a graphite impregnated bronze sleeve. These are still available, in addition to a contemporary version of this 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 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 proven a million times
Because of their torsional overall flexibility, Ever-power couplings can maneuver critical torsional vibrations away from the operating place of mechanical equipment in such a way that no negative effects on the travel train should be expected. Ever-electric power couplings are made from high-quality cast iron. The flexible 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 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-power coupling are subject to compression. If the flexible elements are irreparably destroyed, the hub parts touch metal. This “emergency procedure capability” is necessary, e.g., regarding fire pump drives.
