RFQ Checklist
- Provide incumbent model code (e.g., Flender H3SH12)
- Specify motor power, input speed, and exact required ratio
- Define output shaft type (e.g., hollow shaft with shrink disc)
- List required accessories (fan, heater, PT100, backstop)
Heavy-duty parallel shaft helical gear units designed for extreme continuous industrial loads, perfectly mirroring Flender H-Series dimensional and thermal standards.
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Nominal Torque Range | 3,300 to 1,400,000 Nm | Provides the sheer mechanical strength required to drive multi-ton industrial loads continuously. |
| Ratio Range | i = 1.25 to 450 | Covers everything from high-speed pump drives to ultra-slow kiln rotations. |
Public Selection Matrix
Use this matrix to identify the right engineering review path before requesting model-specific CAD, drawings, or a drop-in replacement check.
| Subseries | Scope | Public Specs to Check | Buyer Use |
|---|---|---|---|
| H parallel shaft helical gearbox | Heavy parallel-shaft helical reducers for conveyors, mixers, crushers, and large process equipment. |
| Use this family when the drive train needs a Flender or SEW-style horizontal parallel-shaft replacement. |
| Heavy conveyor and hoist package | Drive packages with backstop, brake, fan, cooler, and shaft accessory review. |
| Use this family when accessories and duty cycle determine whether a replacement is reliable. |
| Custom shaft arrangement | Solid shaft, hollow shaft, shrink-disc, and foot/flange mounting adaptations for legacy equipment. |
| Use this family when the gearbox must match an existing foundation and connected machine shaft. |
RGB-H
Engineering confirms shaft arrangement, mounting position, service factor, and accessory needs before sending files.
Product-family brief and RFQ worksheet are public.
Released after shaft and ratio configuration review.
STEP, IGES, SolidWorks, 2D PDF or DXF on request
Use the no-login worksheets before sending drawings or requesting model-specific CAD. They help engineering confirm torque, backlash, interface, inspection, and replacement assumptions for H-Series Parallel Shaft Helical Gearbox.
Yes. Center heights, shaft diameters, bolt hole patterns, and torque ratings are designed for direct drop-in replacement.
Yes, we can supply the gearbox mounted on a base frame, complete with motor, fluid coupling, and safety brakes.
