B-Flex couplings consist of 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 as compared to plain bushes.
These couplings are suitable for general engineering application requiring reliable power transmission even under conditions of shaft misalignments which are often unavoidable.

REVOLEX are torsionally flexible, fail-safe pin & bush couplings that are mainly used in applications with high torques and drives subjected to shocks. They are specifically solid, fail-safe, compensate for any kind of shaft displacement while transmitting the torque reliably. The REVOLEX pin & bush couplings can be plugged in axially and are characterized by short dimensions. These pin & bush couplings are generally equipped with hydraulically dismountable pins which means that special tools are not required for disassembly. The coupling components of the REVOLEX® pin & bush couplings are maintenance-free and allow for a smooth disassembly of elastomer rings along with pins in mounted condition.

REVOLEX® pin & bush couplings are usually provided with 80 ShA NBR elastomer rings with the standard material being a true all-rounder. NR elastomers are available for low temperature applications. Apart from that backlash-free, electrically insulating NBR elastomers (coloured in blue) are available which are mainly used in cableway drives.

Cone-Flex couplings consists of sets of resilient “ Cone-Flex” rings with pins & nuts and two flanged hubs of graded cast iron. These “ Cone-Flex” rings are specially shaped to permit the rubber to deflect in all directions and give over four times torsional flexibility as compared to a plain bush.

The function of a flexible coupling is to transmit torque from on shaft to another in cases where limited mis alignment may occur and also to absorb shock loads.

The Fenner Bush Type Flexible Coupling of the cushioned drive type, transmits the torque through high tensile steel bolts to the machine input shaft. Highly developed rubber compounds are used in bushes to absorb shock loads, torsional vibrations and slight misalignments.

Simple and compact in construction, the Fenner Coupling is capable of transmitting high torques at maxium speeds The Flanges are manufactured with cast iron, grade 20 of IS.210. This type of coupling permits drive in either direction and requires neither lubrication nor adjustment after fitting. The flexible bushes remain unaffected by water, dust and atmospheric conditions.

Machines which are to be coupled by flexible couplings should first be aligned with all possible accuracy. The capacity of the coupling will the deal with misalignments which occur by reason of temperature variations or heavy shaft loading. Setting of machine foundations or bearing wear will also cause extra loading to be imposed on the coupling. Any, or all of these conditions can occur once the machines have been coupled.

Flanges are bored to suit requirements and are keywayed to British Standard Specification, Unless otherwise stated. They also be supplied with the listed minium bore to permit machining on site.

Power requirements for the standard coupling range from 0.81Kw to 249Kw at 100RPM and sizes from BC1 to NBC11
