MR Power transmission

The MR simplex sprocket is a single-strand sprocket, machined to mesh with roller chains of 3/8", 1/2", 5/8" or 3/4" pitch. It is used to transmit motion between parallel shafts in machines and equipment. MR manufactures it in SAE 1045 steel, with a hub for mounting on the shaft. It is a key part in low- and medium-speed chain drives.

The designation of the simplex sprocket is read as pitch and number of teeth. For example, Simplex sprocket 1/2" Z8 indicates 1/2" pitch and 8 teeth. The pitch is the distance between centers of two consecutive chain pins; for the same pitch, more teeth give a larger pitch diameter and a lower transmission ratio. The Z suffix is the number of teeth. MR manufactures these sprockets in 3/8", 1/2", 5/8" and 3/4" pitches, with different numbers of teeth as needed.

They are used in chain drives of agricultural machinery, conveyors, elevators, mixers, conveyor belts and industrial equipment in general. Also in the food, chemical and metallurgical sectors. In Argentina, they are common in the oilseed and meatpacking industries and in animal feed plants. MR Accesorios Industriales manufactures them in SAE 1045 steel, which gives them good wear and fatigue resistance.

To select a sprocket, take into account the chain pitch, the number of teeth, the shaft diameter and the mounting type. Check that the sprocket and chain have the same pitch. Proper lubrication and shaft alignment extend service life. If the sprocket has a hub, you can secure it with a key or a set screw. Check chain play and tension periodically.

MR sprockets are interchangeable with those from other brands that follow the same standards for pitch and number of teeth. However, always check the hub dimensions and the bore diameter before replacing. If you need an equivalent, ask us with the original part number and we'll advise you.

The double sprocket is a sprocket with two rows of teeth cut into a single piece, mounted on a hub that makes it easier to secure to the shaft. It is used to transmit motion between chains arranged in parallel or to duplicate the output of a gear reducer. MR Accesorios Industriales manufactures it in SAE 1045 steel and offers it in four standard pitches, with different numbers of teeth to suit each transmission ratio.

The designation of these sprockets is read directly: pitch and number of teeth. For example, Double sprocket 1/2" Z10 indicates a 1/2 inch pitch and 10 teeth per row. The pitch is the distance between the centers of two consecutive teeth and defines the compatible chain; the teeth determine the transmission ratio and the tangential speed. The series covers pitches of 3/8", 1/2", 5/8" and 3/4", always with two rows and a hub. There are no additional suffixes in this line: the code is completed with the pitch and the number of teeth.

They are used in low- and medium-speed chain drives, especially where an output needs to be duplicated or the direction of rotation reversed. They appear in belt conveyors, bucket elevators, food industry machines, packaging lines and material handling equipment. They are also found in the agricultural sector, in seeders and harvesters, and in metalworking shops that assemble their own machines. Domestic manufacturing makes it possible to adapt the sprocket to the specific needs of each plant.

To select correctly, take into account the chain pitch, the number of teeth in each row and the shaft diameter where it is mounted. The hub allows fastening with a key or set screw, depending on the equipment design. Check the alignment between sprocket and chain to avoid premature wear. Proper lubrication and backlash control are key for a long service life. If the environment has dust or moisture, consider additional protection.

Regarding equivalences, standard-pitch sprockets can be interchanged between different manufacturers as long as pitch, number of teeth and hub type match. Not all brands use the same tolerances or the same material, so it is advisable to check the pitch diameter and the bore. For replacements, the safest approach is to compare the complete designation and the critical dimensions. MR manufactures this line in SAE 1045 steel, which ensures adequate strength for most industrial applications.

If you need a double sprocket for your equipment, send us the complete code or the pitch, number of teeth and shaft diameter data via WhatsApp. At MR Accesorios Industriales we advise you so you can choose the right option and we will send you a quote promptly.

Plate sprockets with 1/2" pitch are hubless sprockets designed to transmit motion in roller chains. They are mounted directly on shafts or bushings and secured with set screws or keys. They are used in power transmissions where a specific speed ratio is required. MR Accesorios Industriales manufactures them in SAE 1045 steel, with different numbers of teeth to suit each application.

The designation of these sprockets follows a simple format: Plate indicates that it is a hubless sprocket, the measurement in inches corresponds to the chain pitch, and Z followed by a number indicates the number of teeth. For example, Plate 1/2" Z8 is a sprocket with 1/2" pitch and 8 teeth. The numerical suffixes range from Z8 to Z40, covering a wide range of transmission ratios. The 1/2" pitch is one of the most common in roller chains, and the number of teeth determines the speed and torque that can be transmitted.

These sprockets are used in a wide variety of industries in Argentina, such as food, metallurgy, agriculture and logistics. They are found in belt and roller conveyors, packaging machines, bucket elevators, conveyor belts and transmission systems in general. Their hubless design allows them to be mounted on shafts of different diameters, provided the appropriate bushing or adapter is used. They are ideal for applications where a compact and easy-to-mount sprocket is needed.

To select the correct sprocket, take into account the chain pitch, the number of teeth, the shaft diameter and the type of fastening. SAE 1045 material offers good wear resistance and toughness, although it is not heat treated in this version. It is important to verify the alignment between sprocket and chain to avoid premature wear. Proper lubrication and correct chain tensioning extend the service life of the assembly. If the sprocket is mounted on a shaft without a key, it is recommended to use set screws or fastening screws.

Regarding equivalences and interchangeability, 1/2" pitch sprockets are standard and can replace those of other brands as long as the pitch, number of teeth and outside diameter match. However, verify the hub dimensions and the fastening system, as they may vary between manufacturers. MR manufactures these sprockets with controlled tolerances to ensure smooth engagement with 1/2" pitch chains. If you need advice, our technical team can help you choose the correct option.
