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 may occur and also to absorb shock loads.
We are one of the prominent companies engaged in providing Pinbush Coupling that 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 travel type that is utilized for transmitting the torque through the best possible tensile steel bolts to the machine input. Moreover, these are simple and compact in construction which makes these with the capacity of transmitting huge torques at optimum speeds. These kind of couplings generally permit travel in either way and need neither lubrication, nor adjustment after fitting.

Ever-electrical power 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 as compared to plain bushes.
These couplings are suited to standard engineering application requiring reliable power transmission even below conditions of shaft misalignments which are generally unavoidable.

Description
Ever-power couplings are being used seeing that flexible compensating couplings in all applications requiring a trusted tranny of torque under harsh operating conditions. The conical chairs 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. Various type variants can be found, electronic. g. with brake disk, axial play limiting device, or brake motor couplings.

Pin & Bush Couplings
Simple and almost indestructible, the pin and bush style is ideal for applications that involve security, such as elevator drives or fire pumps. The fail-safe aspect of the design permits the coupling to always be serviced at comfortable intervals, if the elastomer become damaged.
The elastomer elements lessen vibration and dampen impact loads, and 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, as well as a contemporary version of the concept: urethane bushings.

Ever-vitality also manufactures many customized variations of this coupling including brake drum and shear pin type couplings.
Damping shaft coupling that can be used 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 versatility, Ever-power couplings can move critical torsional vibrations from the operating region of mechanical equipment so that no unwanted effects on the drive train are to be expected. Ever-ability couplings are made from high-top quality cast iron. The flexible elements manufactured from synthetic rubber (Buna-N) can be found in different examples of hardness for many applications. Metal pins and flexible elements are designed to ensure that no wear occurs if they are properly fitted.

Did you know?
Original Ever-power elastomers ensure the optimal operation of your system. The flexible elements of the Ever-electrical power coupling are subject to compression. If the flexible elements are irreparably damaged, the hub parts come into contact with metal. This “emergency procedure capability” is required, e.g., in the case of fire pump drives.
