Gear Couplings
WGCI Crowned Gear Coupling
WGCI Crowned Gear Coupling with model-specific technical data, engineering context and assembly drawing for preliminary selection.
Product Overview
WGCI is a crowned gear coupling with paired bore dimensions and a balanced set of D, B and C clearances. The model rows include torque, speed, mass and inertia, allowing the coupling to be compared with the driven machine’s rotating envelope. Use the drawing to distinguish hub, sleeve and shaft-end clearances. The published model tables contain 14 size rows and provide torque values spanning 0.71–160 N·m, permissible-speed values spanning 2300–7500 r/min, bore values spanning 12–260 mm. Use those values for preliminary comparison only; final materials, current standards, manufacturing details and operating suitability require confirmation from RONGXING DRIVE.
Key Features
- Paired-bore WGCI crowned-gear layout
- D/B/C dimensions support envelope matching
- Mass and inertia are listed for rotating assembly review
- The model data provides torque values spanning 0.71–160 N·m, permissible-speed values spanning 2300–7500 r/min, bore values spanning 12–260 mm for a traceable preliminary comparison.
Typical Selection Context
- Industrial drives with two specified shaft bores
- Gear-unit connections where dimensional and inertia checks matter

Engineering Context
This model is best understood from its own construction: Paired-bore WGCI crowned-gear layout; D/B/C dimensions support envelope matching; Mass and inertia are listed for rotating assembly review 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
- Match both bores, bore lengths, D/B/C clearances and shaft ends
- Check speed, torque, lubrication, inertia and guard access
- Send the exact model row, assembly drawing and actual duty data with the inquiry.
Product FAQ
Why are two bore dimensions shown?
The two coupling halves may use different shaft interfaces; both must be matched to the machine.
What does the C dimension control?
Use the drawing to identify the relevant clearance or installation reference before ordering.
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.
