A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. A coupling can be rigid or, more normally, it can be flexible allowing relative radial, axial or angular movement of the two shafts. The coupling transmission is not designed to engage-disengage as a normal operation. Couplings do not normally allow disconnection of shafts during operation, though there do exist torque limiting couplings which can slip or disconnect when some torque limit is exceeded.
The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. By careful selection, installation and maintenance of couplings, substantial savings can be made in reduced maintenance costs and downtime.

| RAPID DRIVES Roller chain Flexible Couplings are compact, all steel, long lasting flexible couplings, capable of transmitting relatively high torques with minimum of space consumption. Consequently, they provide a most economical means of positive transmission of power from one shaft to another.
The simple design and construction of these couplings make them extremely easy to install and disconnect, providing additional economy of operation.
The sprockets are identical in construction, thus providing a balanced unit in operation and reducing effects of vibration. In addition, the flexibility of roller chain plus clearance between the chain rollers and sprocket teeth allow for slight misalignment and shaft end float.
Coupling sizes will usually meet most power transmission requirements. However when necessary special couplings can be furnished on a made to order basis to suit a particular application. In such cases, complete information should be given when requesting a recommendation or quotation. This includes horsepower and RPM requirements, hub dimensions, bore and keyway sizes, and general operating conditions.

| Muff couplings are long cylindrical coupling bored and keyed to fit over both shafts. These are split axially and clamped over both shafts with recessed bolts. Muff couplings consist of a hollow cylinder whose inner diameter is the same as that of the shaft. These are fitted over the ends of the two shafts by means of a gib-head key. The power is transmitted from one shaft to the other shaft by means of a key and a sleeve. It is, therefore, necessary that all the elements must be strong enough to transmit the torque. Muff couplings are the simplest type of rigid coupling for transmitting high torques at high speeds where misalignment is neither present nor desired. Our muff couplings are made from the best quality materials such as cast iron, stainless steel, alloy steel and many more materials and are available in various sizes. We also customize muff couplings as per our clients' requirements and specifications. Various features that we offer in our muff couplings are as follows: Our muff couplings undergo stringent quality tests before being dispatched to our clients. |

| | Rigid couplings are used when precise shaft alignment is required; shaft misalignment will affect the coupling's performance as well as its life. These couplings connect rotating members such as shafts so that these couplings secure onto both members and provide transmission of torque and motion. Rigid couplings are used where the axes of the shafts are directly in line. A rigid coupling is suitable for shafts in close alignment or held in alignment without inducing destructive forces in shafts or bearings. Our rigid couplings are available in one and two-piece designs, with and without key-ways, in aluminum, carbon steel, alloy steel, stainless steel and many more materials. A large number of standard sizes are available in straight and step bore combinations to fit shafts of various dimensions. Extra steps are taken in the manufacturing of our rigid couplings to provide important performance benefits. These rigid couplings are corrosion and abrasion resistant and fail-safe since stringent quality standards are followed while manufacturing these couplings. Our rigid couplings are also very economical in prices. Various features of our rigid couplings are as follows: |
