Gear Couplings
CL Gear Coupling
CL Gear Coupling with model-specific technical data, engineering context and assembly drawing for preliminary selection.
Product Overview
CL is a conventional gear coupling with separate hub and sleeve dimensions in the model table. The published rows pair nominal torque and permissible speed with two bore arrangements, bore length, flange dimensions, inertia and mass. This makes CL a useful reference when a straightforward gear-coupling envelope is required and lubrication access can be planned. The published model tables contain 19 size rows and provide torque values spanning 0.71–1000 N·m, permissible-speed values spanning 300–3780 r/min, bore values spanning 18–560 mm. Use those values for preliminary comparison only; final materials, current standards, manufacturing details and operating suitability require confirmation from RONGXING DRIVE.
Key Features
- Conventional gear-coupling sleeve and hub geometry
- Two bore arrangements are carried through the table
- Inertia and mass are supplied for rotating-equipment checks
- The model data provides torque values spanning 0.71–1000 N·m, permissible-speed values spanning 300–3780 r/min, bore values spanning 18–560 mm for a traceable preliminary comparison.
Typical Selection Context
- General industrial gear-unit and motor shaft connections
- High-torque lines where a conventional sleeve envelope is acceptable

Product FAQ
What differentiates CL from CLZ?
The two families use different bore and sleeve dimension arrangements; compare their drawings and rows.
Why include inertia in the comparison?
Inertia affects acceleration, braking and torsional response of the connected drive.
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.
