TSUBAKI chain coupling selection requires distinguishing the transmission connection from its constituent parts. In this line, a final letter can change the scope of the catalog record, so do not shorten the request before identification. State whether you need a coupling, body or casing. This distinction relates the replacement to the existing mounting and avoids treating every subcategory item as a complete assembly.

CR3812 is named a chain coupling, CR3812H a chain coupling body and CR3812K a chain coupling casing. The catalog names clearly distinguish the assembly from its components. All share CR3812, but H and K remain because they identify different components. Digits are not split here into tooth counts or dimensions. Confirm geometry and contents using the record or parts drawing for the requested reference.
At the connection between transmission sections, inspect shaft ends and coupling position relative to supports. For a replacement body, document bores and connections on both sides. For a casing, show its relationship to the enclosed assembly and its fastenings. A closed exterior photograph does not necessarily identify the parts inside, so add a parts drawing or photographs taken during maintenance.
For a quote from MR Accesorios Industriales, send the full designation, shaft or component dimensions, photographs and application. Add quantity and mark the required part on an assembly drawing. State which parts remain. This preserves the distinction between replacing one component and requesting the coupling identified in the catalog.
No. It is recorded as a chain coupling body; H must remain to define the requested part.
In these codes K identifies the casing, a component distinct from the body and coupling without a final letter.
Copy the readable marking, photograph the entire part and explain its installed location. Do not add H or K by assumption; geometry is used to review identification.

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 sells them in Buenos Aires, Argentina, and advises you on choosing the model for your application.
Just the manufacturer part number is enough: we will quote it and provide dimensions and equivalents via WhatsApp or email.
