Power transmission

The power transmission system is the heart of many machines – it is responsible for the efficient, controlled, and effective transmission of torque. Our offer includes a complete selection of components for building and modernizing drive systems, ranging from belts and chains to taper bushes and clamping rings. This allows you to design systems tailored to both lightweight and extremely heavy-duty applications.

The range of components available in our offer:

Drive belts – ensure quiet and flexible operation, ideal for high-speed machinery.
Pulleys – guarantee optimal power transmission and stable engagement with belts.
Drive chains – enable the transmission of high loads without any loss of precision.
Sprockets – ensure secure meshing and smooth chain travel.
Taper bushes – facilitate quick, backlash-free mounting and dismounting of rotating components.
Hubs – stabilize the system, ensuring perfect seating of wheels on shafts.
Couplings – compensate for misalignment and protect the drive from overload.
Keyless clamping elements – enable secure mounting of components without the need for shaft machining.
Drive mounting accessories – allow you to adjust and build a system with the exact parameters required by your application.

Sprockets

Sprockets are a crucial link in chain-based power transmission systems – they are responsible for stable meshing and uniform movement of the entire system. Our offer includes both pilot bore sprockets with hubs and models adapted for taper bushes, allowing you to match the configuration to specific working conditions. The variety of diameters and tooth counts enables the creation of systems ranging from compact setups to heavy industrial ones. Here you will find:

sprockets with hubs – quick to install and ready for operation without additional parts;
taper bore sprockets – allow for multiple reuse and efficient servicing;
single and multi-strand sprockets – let you adapt the drive to the required load capacity and speed;
sprockets in small and large pitches – offer the possibility to build systems of various scales and gear ratios.

Pulleys

Pulleys are responsible for power transmission in systems utilizing V-belts, timing belts, or multi-ribbed belts. Their correct selection directly affects the operational smoothness and service life of the entire system. Thanks to a wide choice of variants, you can easily configure a drive tailored to your specific requirements. What will you find in this section?

SPZ, SPA, SPB, SPC pulleys – proven solutions for high-speed belt drive systems.
Timing pulleys – ensuring precise motion synchronization.
Taper lock pulleys – enhance servicing options and reduce replacement downtime.
Single and multi-groove pulleys – providing the capability to build systems with various power ratings.

Taper bushes

Taper bushes are indispensable wherever stable mounting and easy component replacement on a shaft are required. Thanks to their conical design, they guarantee a backlash-free connection while allowing quick removal of a pulley or hub without affecting the shaft. In our offer, both small bushes and models for heavy-duty mechanics are available off the shelf. At Marat, we have:

bushes in standard sizes from TB1008 to TB5040 – enabling mounting on virtually any shaft;
versions with various bore diameters – allowing connection of drive components with many types of axes;
heavy-duty models – ensuring safety even during intensive operation;
easy-to-service bushes – saving time during the disassembly of drive systems.

Chains and links

Drive chains are among the most robust components used in power transmission systems. Due to their design, they effectively transmit force under harsh conditions, such as heavy loads or contamination. We also offer roller links, offset links, and connecting links that allow you to adjust the chain length and structure. Our product range includes:

single and multi-strand chains – stretch-resistant, ensuring a long service life;
connecting links – accelerate assembly and enable quick replacement of a damaged section;
offset links – help perfectly match the chain length to the system;
chains in one-meter packaging – convenient for creating drives with non-standard dimensions.

Belts

Belts are an excellent choice for systems requiring low noise, smooth operation, and slip resistance. In our offer, you will find various types of belts: V-belts, timing belts, and specialized variants, allowing you to perfectly match them to the required power and rotational speed. What sets our product range apart?

SPZ, SPA, SPB, SPC V-belts – perform exceptionally well in fast systems with variable loads.
Timing belts – provide full synchronization without the risk of slippage.
Reinforced belts – maintain durability even when operating in harsh environments.
Belts in many lengths – allow you to adjust gear ratios without additional machining.

Hubs

Hubs form the foundation for stable mounting of drive wheels, especially in systems requiring high seating accuracy. Their simple design and material resistance ensure secure power transmission and long-term operation. In this category of our store, we offer:

taper bore hubs – allow you to connect a shaft with a wheel without mechanical machining;
high-resistance steel hubs – guarantee safety at high speeds;
universal versions – perform well in many machines and power transmission systems;
hubs for precision applications – reduce runout and improve motion smoothness.

Keyless clamping elements

Keyless clamping elements enable the mounting of wheels and discs on shafts without keys and keyways, eliminating the need for additional machining. They create a strong, self-locking connection that works exceptionally well under variable loads. This category includes:

clamping rings – ensure quick and secure mounting on shafts of various diameters;
locking assemblies – stably seat components inside hubs and sleeves;
compact versions – ideal for devices with limited mounting space;
high-strength rings – withstand vibrations and mechanical shocks well.

Couplings

Couplings are damping and protective elements that safeguard the drive system against vibrations, overload, or shaft misalignment. They ensure a longer service life for the entire system and more stable machine operation. We offer the following couplings:

flexible couplings – dampen vibrations and protect gearboxes;
jaw couplings – transmit high torques with minimal wear;
torsional couplings – increase operational smoothness under variable loads;
precision couplings – ideal for applications requiring accurate positioning.

Who did we prepare the products in this category for? Among others, for:

design engineers developing power transmission systems who require a wide selection of compatible components.
maintenance departments that need immediate access to belts, chains, taper bushes, and coupling elements.
machine manufacturers and system modernizers looking for parts with proven durability and fast delivery times.

A rich selection of power transmission components allows you to create high-efficiency and reliable systems under all operating conditions. The offered products – from belts to couplings – enable precise adjustment of drive parameters to specific applications. Thanks to constant availability and fast deliveries, you can carry out your projects without unnecessary downtime.
