How to quote RENOLD chains, couplings, sprockets and variators

RENOLD is a brand of power transmission components that MR sells. We work with chains, couplings, gears and speed variators. Each line has specific applications in production and maintenance equipment.

In Argentina, maintenance managers usually ask for these products by code or by size. We quote based on that data. A photo or an engraved number is enough to get started.

To get a quote, it is best to identify the product line correctly. A roller chain is not the same as a flexible coupling. Each one has its own nomenclature and reference codes. If you are unsure, send us a photo of the part and we will help you identify it.

RENOLD transmission chains are used to transmit motion between shafts in industrial machines. They are common in conveyors, elevators, agricultural machinery and process equipment. They are manufactured in different pitches and standards, such as ANSI or BS. The choice depends on load, speed and working environment.

To order a chain, the most practical thing is to indicate the pitch and the number of strands. For example, a 1/2 inch pitch chain, single or double. You can also quote by the code engraved on the links. If the chain is very worn, measure the pitch between pins and count the strands.

A common mistake is confusing transmission chain with conveyor chain. The former transmit power; the latter drag material. They are ordered differently. If you are unsure, send a photo of the equipment and the chain section. We will quote the correct option.

RENOLD couplings connect two shafts and compensate for misalignment. They are used between motors and pumps, compressors, gearboxes and other rotating equipment. There are rigid, flexible, jaw and gear models. Each type absorbs different levels of angular, radial or axial misalignment.

To quote a coupling, you need the shaft diameter and the distance between ends. The catalog code also works if you have it. Many couplings have an elastic element that is replaced over time. That spare part is ordered separately depending on the model.

A frequent mistake is choosing a coupling only by shaft diameter. Torque and rotation speed must also be considered. If you do not have that data, send us the motor nameplate and the equipment description. We will help you select the right coupling.

Sprockets are used with chains and gears in gear transmissions. Sprockets are mounted on shafts and work together with chains. Gears are used in gearboxes, speed reducers and precision mechanisms. They are manufactured in different modules, numbers of teeth and materials.

To order a sprocket, indicate the chain pitch, the number of teeth and the bore diameter. If it is a gear, you need the module, the number of teeth and the face width. Many parts have the code engraved or stamped. With that data the quote is faster.

A common mistake is ordering a sprocket without checking the hub type. It can be with a pilot bore, with a keyway or with a tapered bushing. You also need to confirm whether it is for single, double or triple chain. If you have the old part, take a photo of the front and side. With that we will quote the replacement.

RENOLD mechanical variators allow you to change the output speed of equipment without electronics. They are used in conveyors, mixers, feeders and machine tools. Adjustment is done manually or with an actuator. They are robust and suitable for environments where electronic variators are not convenient.

To quote a variator, you need the motor power and the desired speed range. The equipment code also works if it is visible. Many variators are installed between the motor and the gearbox. In those cases, you must verify the mounting type and the direction of rotation.

A common mistake is confusing a mechanical variator with a frequency inverter. The former changes the transmission ratio; the latter changes the electrical frequency. If your application requires changing speed without electronics, tell us about the equipment and we will look into it.

Most RENOLD products have an engraved identification or a label. On chains, the code is usually on the links or on the connector. On couplings and gears, it may be on the hub or on the face. If the part is very worn, sometimes the code is erased.

When there is no code, it can be identified by measurements. For chains, measure the pitch and the inner width. For sprockets, count the teeth and measure the outer diameter. For couplings, measure the shaft diameter and the distance between flanges. With that data, we will quote the replacement.

A photo of the part next to a ruler or caliper also works. That way we can estimate the dimensions and compare with the catalog. If you have the equipment manual, even better. Send all the information you have and we will reply shortly.

To quote any RENOLD product, write to us on WhatsApp or by email. Tell us what line you need and send us the code, the size or a photo. If it is a spare part for a specific equipment, indicate the machine brand and model. With that we prepare the quote.

You do not need to know the exact code. If you have the old part, take photos from different angles. If it is a chain, measure the pitch and count the strands. If it is a coupling, measure the shafts. We take care of identifying the correct product.

Once we have the data, we will quote the RENOLD product you need. We advise you on the selection. Send your inquiry and we will reply shortly.
