TSUBAKI CR series couplings are roller chain couplings that transmit torque between two shafts flexibly. They absorb angular, parallel and axial misalignment, and dampen vibration and shock. They are used in equipment where a strong, low-maintenance connection is needed, with good tolerance to weather and load. MR Accesorios Industriales supplies them in Buenos Aires, Argentina, and advises you on choosing the model for your application.
The CR series designation is read in steps: the letters CR identify the roller chain coupling family, and the numbers that follow indicate the size and number of teeth on the hubs. For example, CR3812H corresponds to a coupling with a 38-tooth hub and a 12-tooth hub, while CR4014H combines 40 and 14 teeth. The H suffix indicates the hub configuration with a special finish. These data define the permissible shaft diameter and torque capacity.
In Argentine industry, TSUBAKI CR series couplings appear in conveyors, mills, mixers, pumps, fans and machine tools. They are chosen when there is misalignment between shafts or when a robust transmission is required to withstand starts under load. They are also used in mining, food and process plant equipment, where the environment may be dusty or humid. Their metal construction makes them suitable for continuous service under demanding conditions.
To select a CR coupling, take into account the nominal torque, rotation speed, shaft diameters and permissible misalignment. Installation requires aligning the hubs as precisely as possible, lubricating the chain according to the duty cycle and checking tension. Proper sealing and periodic lubrication extend service life. If the equipment operates with reversing or pulsating loads, it is advisable to oversize the coupling.
Roller chain couplings are interchangeable between brands in terms of dimensions and capacities, provided the pitch, number of teeth and shaft diameter match. Do not invent part numbers: compare standardized dimensions and consult a specialist. At MR Accesorios Industriales we can guide you on equivalence with other brands and verify compatibility with your equipment.
If you already have the part number of the TSUBAKI CR series coupling you need, send it by WhatsApp to MR Accesorios Industriales and we'll quote you shortly. We can also help you identify the model if you send us the shaft dimensions and the power to be transmitted. More than 80 years of experience in industrial distribution back us in advising you on selection and installation.

Frequently Asked Questions
- What does the designation CR3812H mean?
- CR indicates a roller chain coupling. The numbers 38 and 12 correspond to the number of teeth on each hub, and the final H identifies a hub configuration with a special finish. These data define the size and torque capacity of the coupling.
- How do I choose the right coupling for my machine?
- You need to know the torque, speed, shaft diameters and expected misalignment. These data are used to select the CR model that meets the requirements. If you don't have them, send the dimensions by WhatsApp and we'll help you identify it.
- Are TSUBAKI CR series couplings interchangeable with other brands?
- Yes, roller chain couplings are generally interchangeable if the pitch, number of teeth and shaft diameter match. Don't rely on the part number alone: verify the standardized dimensions. At MR we advise you to find the equivalent.
