Power Transmission Products


A belt is a ring of flexible material used to mechanically connect two or more rotating shafts, often in parallel. Belts can be used as a source of motion to efficiently transfer power or monitor relative motion.


The machine elements that transfer the energy from the motor shaft to the rotated shaft with the help of one or more belts are called pulleys. Pulley models, which are generally made of cast iron or aluminum, are preferred because they offer the advantage of robust and long-lasting use. A pulley generally consists of three main parts:

  • Spoke: The part of the circle that the belt contacts. Hub: It is the part that allows the pulley to be attached to the shaft. Body: It is the part that connects the spoke and the hub.

There are many different types of pulleys available. The main ones are v-belt pulleys, timing pulleys and poly-v pulleys. Pulleys are preferred because they are advantageous in terms of cost. They are quiet-running elements and offer a high efficiency value. They do not need extra maintenance such as lubrication.

Tapered Bushes

Conical bushings ensure that the pulley or gear systems to be used in the transmission elements are attached to the shaft in a serial and run-out manner. It is produced in different shaft diameters and standard wedge sizes according to its dimensions. Thus, it also saves gears or pulleys from operations such as internal machining keyway opening.

Conical Locks

Conical Lock systems are systems that transmit torque through the tension created as a result of the radial force applied to the shaft and hub by tightening the bolts on it. Conical Lock systems increase productivity by reducing material, machining and operational waste.


Gears are mechanical transmission elements used to transfer motion and power between machine components. Gears, working in pairs, engage their teeth with the teeth of another corresponding gear or gear component, which prevents slippage during transmission operation.


A sprocket is a cogwheel or wheel with teeth designed to transfer motion to a chain, track, or other holed or recessed material. The name 'sprocket' generally describes any wheel where its radial protrusions engage a chain that runs over it. Compared to smooth rollers, sprockets have ridges that allow them to mate with the chain or track. Unlike sprockets, sprockets are not directly coupled to each other. Sprockets are used in bicycles, motorcycles, cars, tracked vehicles and other machinery to transmit rotational motion between two shafts where the sprockets are not suitable, or to a part, track, etc. Used to apply linear motion.
