Flexible Couplings
JSB Grid Coupling
JSB Grid Coupling with model-specific technical data, engineering context and assembly drawing for preliminary selection.
Product Overview
JSB is a grid coupling with an explicit lubricant-quantity field. Its model table gives nominal torque, speed, bore, bore length, overall length, D, clearance C, mass and lubricant quantity. The grid element and lubrication arrangement should be considered together: maintenance access and a suitable cover are part of the installation decision. The published model tables contain 16 size rows and provide torque values spanning 45–63000 N·m, permissible-speed values spanning 1600–6000 r/min, bore values spanning 18–260 mm. Use those values for preliminary comparison only; final materials, current standards, manufacturing details and operating suitability require confirmation from RONGXING DRIVE.
Key Features
- Grid element with model-specific clearance
- Lubricant quantity listed for each size
- Bore, overall length, D and mass data
- The model data provides torque values spanning 45–63000 N·m, permissible-speed values spanning 1600–6000 r/min, bore values spanning 18–260 mm for a traceable preliminary comparison.
Typical Selection Context
- Motor, pump and fan drives using a lubricated grid element
- General machinery where grid replacement and guard access can be planned

Engineering Context
This model is best understood from its own construction: Grid element with model-specific clearance; Lubricant quantity listed for each size; Bore, overall length, D and mass data 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
Information Required for Selection
- Confirm bore, overall length, clearance C and grid access
- Match torque and speed, then verify lubricant quantity, cover and maintenance space
- Send the exact model row, assembly drawing and actual duty data with the inquiry.
Product FAQ
Why is lubricant quantity listed for JSB?
The grid element depends on the specified lubrication amount and service access.
Should a cover be included in the inquiry?
Confirm the required guarding and whether speed or maintenance conditions call for a cover.
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.
