Coupling - Import export

Chrome-coated air couplers are designed to provide a durable and corrosion-resistant connection between air hoses and tools. The chrome plating helps to prevent rust and corrosion, ensuring a longer lifespan for the coupler. These couplers work by connecting to the end of an air hose, while the other end is attached to an air tool or accessory. The coupler allows air to flow through the system, providing power to the tool or equipment. Ronix 40SM is such a coupler that offers all of these benefits and so much more

Air couplers are essential tools used in pneumatic systems that are used to connect various air tools and hoses. They provide a secure and airtight seal between the air hose and the tool, creating a transfer corridor for compressed air to move in. Air couplers are beneficial to those who work in industries that utilize air tools, such as construction, automotive, and manufacturing. Armed with a large body that features a chrome coating, Ronix 20SP is such a tool and is ready to help you create or maintain your pneumatic system.

Air couplers are essential components in pneumatic systems that provide a safe and reliable connection between various air tools and hoses. They work by allowing compressed air to flow through different components of the system, enabling the tools to function efficiently. Anyone who uses pneumatic tools regularly, such as mechanics, construction workers, or DIY enthusiasts, will undoubtedly need air couplers to keep their system running. Keeping this importance in mind, we have designed and manufactured the Ronix 20SM air coupler with a chrome-coated body and an operating pressure of 10kgf/cm².

Air couplers are small connectors used to join two hoses or tubes in an air system. They offer a quick and secure connection between two parts of an air system, allowing the flow of compressed air from one tool to another. From enabling air-powered tools such as air nailers and staplers to transferring compressed air from an air compressor to the other side of a workshop, air couplers can be used in a variety of industries. Ronix 20SF is such a coupler that combines a large body with a chrome coating to offer long-lasting excellent performance.

Air couplers which are also known as air fittings are mechanical devices that connect air hoses to air tools or pneumatic equipment. They work by allowing the flow of compressed air from an air compressor or air tank to the air tool or equipment, which is used to power them. Our 20SH model is such an air coupler that can be used to deliver and transfer high pressure from an air compressor to its destination. Made with a larger body compared to its competitors in addition to its chrome-coated exterior, Ronix 20SH will be the last air coupler you will ever buy

Air couplers, also known as air fittings, are essential components in pneumatic systems used to connect various air tools to an air compressor or air hose. They work by using a simple push-and-pull mechanism that allows for quick and easy connection and disconnection of air hoses and tools. Those who work in the automotive, construction, and manufacturing industries, as well as DIY enthusiasts and any other individual that uses compressed air to any extent, may find air couplers beneficial. They are useful for powering various pneumatic tools, such as impact wrenches, spray guns, and sanders. Air couplers are also handy for inflating tires, powering pneumatic nailers, and staplers, and cleaning dusty or dirty surfaces. Featuring a chrome coating and a large body, Ronix 20PP is such an air coupler that can be used in any situation that needs the transfer of compressed air.

2-way air couplers are devices used for connecting two hoses or other pneumatic tools to a single source. They work by having two female connectors that attach to the ends of the hoses, and a male connector in the center that can be inserted into an air compressor or other air-powered tools. When attached, these connectors allow for compressed air to flow through both hoses simultaneously. 2-way air couplers are particularly beneficial for those who need to use multiple pneumatic tools at once, as they can increase efficiency and save time and space. For example, in automotive repair shops, these couplers can be used to connect two air-powered tools such as a pneumatic impact wrench and a pneumatic ratchet to a single air compressor, allowing mechanics to switch between tools without having to disconnect and reconnect air hoses.

RINGFEDER® Flange Couplings are the better alternative to press fits. Neither additional components such as keyways or wedges, nor a warming of the outer section and cooling of the inner section are required. The flange coupling is simply pushed onto the shaft and fastened so it is frictionally engaged by tightening the screws in the shrink disc. They transfer torque and bending moments as well as axial and radial forces.

Shaft Couplings RfN 5071 Standard series – this range is the most popular, being used in most applications. Characteristics Shrink discs are the modern method for creating a mechanical shrink fit. The shrink disc consists of either one or two thrust rings with tapered bores and a mating tapered inner ring. By tightening locking screws the thrust rings are drawn together compressing the inner ring and applying pressure to the outside of the hub clamping it to the shaft. Being positioned around the hub there is only one interface transmitting the loads giving the shrink disc method distinct advantages such as offering the possibility of very concentric and well balanced connections that are suited to high speed applications. Traditional shrink fits require complicated calculations, close machining tolerances and fine surface finishes, they also need considerable effort with mounting and removal. The Shrink Disc connection has none of these disadvantages and is better than any of...
