Seals are incorporated into a mechanical assembly containing fluids to prevent their leakage at the points where different parts of the assembly meet. An O-ring seal is one of the most widely used seal. It is also known as toroidal seal. An O-ring seal is used in applications, ranging from garden hose couplings to aerospace or oil and gas duties as it is a simple, space saving and cost effective design. In view of this, information about construction, working, properties of elastomeric (rubber) compounds, design considerations, size (dimensions) standards, quality acceptance criteria, installation guidelines, storage, and maintenance (failure analysis) of O-rings is given in the following booklet.

Keyless shaft locking devices/assemblies/elements/bushings (also called friction locks or shaft to hub connections) are standard machine elements used to connect shafts and hubs. They are capable of transmitting torque, radial forces, axial forces and bending moments. They also have many advantages over traditional methods. In view of this, information about construction, working and installation of keyless shaft locking devices is given in the following article.

Fluid couplings or hydraulic couplings work on the hydrodynamic principle. Fluid couplings are often used to drive large inertia machines in combination with squirrel cage motors. They permit a load free acceleration of the motor and consequently with increasing oil fill, provide a soft/gentle quasi steady state start-up of the machine. They are used in drives for conveyor systems and in heavy industry. Information about construction, working, installation, operation and maintenance of a fluid coupling is given in the following article.

Freewheels are “overrunning” clutches, i.e., they will drive in one direction but overrun (freewheel) in the other direction. They are used as backstops, overrunning clutches and indexing freewheels. Freewheels are widely used as backstops. A backstop when mounted on an inclined conveyor head shaft is commonly called holdback. Information about construction, working and installation of freewheels is given in the following article.

Electro hydraulic thruster drum brake is a device used to retard the speed of moving machinery and to stop it accurately to the desired position. Thruster operated drum brakes are spring applied and electrically released. These brakes are mainly used in material lifting and handling equipment in the field of applications like ports, steel and metallurgy, mining, etc. mainly because of their “smooth” braking and 'fail-to-safety' designs to ensure safety to men and machines. In view of this, information about construction, working, installation and maintenance of electro hydraulic thruster drum brakes and thrusters is given in the following article.

V-belt drive systems (also called friction drives) are an economical option for transmitting power in industrial, automotive, commercial, agricultural and home appliance applications. To derive maximum benefit from a well-designed V-belt drive, it is important that the simple installation and maintenance procedures are closely followed. In view of this, information about construction, installation and maintenance of power transmission V-belt drives is given in the following booklet.

Pivoted motor bases are widely used to automatically control the belt’s tension to minimize maintenance and maximize belt life. In view of this, information about construction and working of pivoted motor bases, also called reactive torque motor bases for belt drives is given in the following article.
