Gear Couplings
NGCLZ Crowned Gear Coupling with Brake Drum
NGCLZ Crowned Gear Coupling with Brake Drum with model-specific technical data, engineering context and assembly drawing for preliminary selection.
Product Overview
NGCLZ is the Z-form crowned gear coupling with a brake drum. Its table retains the Z-form bore and D3 geometry while adding drum dimensions, torque, speed, inertia and mass. Select it as a complete coupling-and-brake interface: the bore, tooth-space lubrication, drum clearance and brake duty all need to agree with the machine drawing. The published model tables contain 15 size rows and provide torque values spanning 355–100000 N·m, permissible-speed values spanning 950–4000 r/min, bore values spanning 20–250 mm. Use those values for preliminary comparison only; final materials, current standards, manufacturing details and operating suitability require confirmation from RONGXING DRIVE.
Key Features

Engineering Context
This model is best understood from its own construction: Z-form crowned gear geometry with brake drum; Drum and D3 dimensions distinguish the variant; Torque, speed, inertia and mass support full 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

Product FAQ
Why is NGCLZ not interchangeable with NGCL?
The Z-form bore and dimension arrangement changes the shaft and drum interface.
What should be sent for a brake-equipped inquiry?
Send coupling torque, brake torque, speed, bore, drum clearance and the complete mounting drawing.
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.
