Main Products
Sprockets
Sprockets
A sprocket, sprocket-wheel or chainwheel is a profiled wheel with teeth that mesh with a chain, track or other perforated or indented material.The name ‘sprocket’ applies generally to any wheel upon which radial projections engage a chain passing over it. It is different from a gear in that sprockets are never meshed together directly, and differs from a pulley in that sprockets have teeth and pulleys are smooth except for timing pulleys used with toothed belts.
Transmission Chains
Transmission Chains
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.Chains are mechanical components that are used to transmit power and motion between different parts of a machine. Chains are typically made of metal and consist of a series of interlocking links that allow the chain to transmit power from a driving component to a driven component, such as a wheel or conveyor.Chains are commonly used in various industrial applications, including in manufacturing, mining, construction, and agriculture. Chains are also used in transportation equipment, such as bicycles and motorcycles, as well as in lifting equipment, such as cranes and hoists.There are many different types of chains available, each with its own specific design and applications. Some common types of chains include:Roller chains: Roller chains are the most commonly used type of chain and consist of a series of interlocking rollers and pins. Roller chains are known for their high strength and durability and are used for applications such as powering conveyor belts and driving heavy machinery.Leaf chains: Leaf chains are narrower and longer than roller chains and are designed to handle heavy loads while maintaining their tensile strength. Leaf chains are commonly used in applications such as lifting equipment.Silent chains: Silent chains are designed to operate quietly and smoothly and are commonly used in applications such as printing presses and automotive engines.Agricultural chains: Agricultural chains are designed for use in farming and agricultural applications, such as powering irrigation systems and supporting equipment for planting and harvesting.Proper maintenance of chains is important to ensure their longevity and reliable performance. This includes regular cleaning and lubrication to prevent rust and corrosion and to ensure smooth motion between the links.In summary, chains are mechanical components used in various industrial and transportation applications to transmit power and motion between different parts of a machine. Chains come in different designs and configurations to accommodate specific applications and must be properly maintained to ensure reliable performance.
Gearboxes&Reducers
Gearboxes&Reducers
Gearboxes and reducers are mechanical components used in power transmission to reduce the speed of a motor or engine while increasing the torque to provide more power to an output device. They are commonly used in machinery and equipment to transfer power from one rotating component to another.A gearbox is a mechanical device of a transmission system that transmits power from one rotating component to another, as well as changing the speed, direction, and torque of the power source. It uses multiple gears of different sizes and configurations, such as spur, helical, bevel, and worm gears, to adjust the speed and torque of the output shaft relative to the input shaft. Gearboxes are essential components in many types of industrial equipment such as cars, heavy machinery, and processing equipment, where it is important to control the speed and torque ratio of the power transmitted.
Gears & Racks
Gears & Rack
a toothed wheel that engages with another toothed wheel or with a rack in order to change the speed or direction of transmitted motion.A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called cogs), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque, creating a mechanical advantage, through their gear ratio, and thus may be considered a simple machine. The rotational speeds, and the torques, of two meshing gears differ in proportion to their diameters. The teeth on the two meshing gears all have the same shape
Power Lock
Power Lock & Locking assembly
A power lock is a mechanical device used to connect two rotating shafts together to transmit power from one shaft to another. It is designed to provide a secure and strong connection that allows the transmitted power to be transferred without slipping or coming loose.Power locks are commonly used in industrial applications where high torque is required and in environments where equipment operates under high vibrations or shock loads. They consist of two halves that are bolted together around a shaft, creating a rigid connection that prevents relative movement between the two shafts.

This type of pulley is designed with a toothed profile around its rim to mesh with teeth on the belt.The timing pulley and timing belt work together to provide accurate power transmission in machines and equipment. The toothed profile on the pulley and belt ensures that the rotation of the output shaft is synchronized with the rotation of the input shaft, which is important for precision positioning and timing in applications that require high accuracy.
Universal Joint
Universal Joint
A universal joint (U-joint) is a mechanical component used in power transmission systems to allow for rotational movement between two shafts that are not aligned in a straight line. It consists of a cross-shaped element that connects two yokes, with bearings at each end of the cross. The bearings allow a degree of angular misalignment between the two shafts while transmitting torque and rotary motion between them.
Tensioner
Tensioner
A tensioner is a mechanical component used in power transmission systems to maintain the proper tension of a belt, chain, or other flexible power transmission element.
