Flexible Couplings
JSP Grid Coupling with Brake Disc
JSP Grid Coupling with Brake Disc with model-specific technical data, engineering context and assembly drawing for preliminary selection.
Product Overview
JSP combines a grid coupling with a brake disc. Its table separates braking torque from permissible speed and adds maximum bores, intermediate length, disc diameter/width, clearances, mass and an unverified final field. The disc interface and grid element must be checked as one rotating assembly. The published model tables contain 19 size rows and provide the model-specific dimensional fields requiring confirmation. Use those values for preliminary comparison only; final materials, current standards, manufacturing details and operating suitability require confirmation from RONGXING DRIVE.
Key Features
- Grid coupling with brake-disc interface
- Braking torque and disc dimensions are explicit fields
- One unconfirmed field is withheld from the public table
- The model table provides the model-specific dimensional fields requiring confirmation for a traceable preliminary comparison.
Typical Selection Context
- Brake-equipped motor, hoist and conveyor connections
- Drive lines requiring a disc interface with a flexible grid element
Technical Data Availability
Detailed technical information for this model requires confirmation from RONGXING DRIVE before size selection or ordering.
Engineering Context
This model is best understood from its own construction: Grid coupling with brake-disc interface; Braking torque and disc dimensions are explicit fields; One unconfirmed field is withheld from the public table Industry selection practice checks torque and speed together with the movement, shaft interface, installation envelope and maintenance conditions allowed by that construction.
Technical Notes
- Model symbols, units and empty or placeholder cells are shown as published.
- Dimension letters must be interpreted with the relevant assembly drawing.
- Published values support preliminary review and do not replace final engineering confirmation.
Assembly Drawing

Technical confirmation required. Some model-specific details require confirmation from RONGXING DRIVE before size selection or ordering.
Information Required for Selection
- Provide braking torque, disc diameter/width, bore, speed and clearance
- Confirm grid lubrication, intermediate length, mass basis and guard arrangement
- Send the exact model row, assembly drawing and actual duty data with the inquiry.
Product FAQ
What distinguishes JSP from JSL?
JSP uses a brake disc and lists disc dimensions; JSL uses a brake drum and a different bore layout.
Why is a source field not shown?
Its label is technically unverified, so it is not presented as a reliable specification.
Are the published values final ordering values?
No. They are preliminary engineering data; confirm the selected model, drawing, dimensions, materials, standard and suitability with RONGXING DRIVE.
Technical data is provided for preliminary selection. Confirm the final model, dimensions, materials, applicable standard and operating suitability with RONGXING DRIVE before quotation, manufacture or installation.
