Flexible Couplings
HTLA H-Type Flexible Coupling
HTLA H-Type Flexible Coupling with model-specific technical data, engineering context and assembly drawing for preliminary selection.
Product Overview
HTLA is an H-type flexible coupling with three bore options in the model table. It provides nominal torque, permissible speed, bore length, b/b1, D, D1, S, mass and inertia, allowing a compact H-profile connection to be checked against the shaft extensions. The first column is not used as a specification. The published model tables contain 13 size rows and provide torque values spanning 18–4000 N·m, permissible-speed values spanning 2000–5000 r/min, bore values spanning 12–110 mm. Use those values for preliminary comparison only; final materials, current standards, manufacturing details and operating suitability require confirmation from RONGXING DRIVE.
Key Features
- H-type flexible coupling profile
- Three-bore and bore-length choices by model
- b/b1 and S dimensions define the compact envelope
- The model data provides torque values spanning 18–4000 N·m, permissible-speed values spanning 2000–5000 r/min, bore values spanning 12–110 mm for a traceable preliminary comparison.
Typical Selection Context
- Compact motor and gearbox interfaces with H-profile hubs
- Industrial drives where bore choice and axial space are constrained

Engineering Context
This model is best understood from its own construction: H-type flexible coupling profile; Three-bore and bore-length choices by model; b/b1 and S dimensions define the compact envelope 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 which of the three bore positions is required
- Check torque, speed, b/b1, D/D1, S, inertia and shaft extension
- Send the exact model row, assembly drawing and actual duty data with the inquiry.
Product FAQ
Why are multiple bore positions shown?
The H-type hub can be configured for different shaft interfaces; the drawing identifies the selected position.
What does the blank table column mean?
It is not a published specification; rely on the named dimensions and 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.
