The F family uses parallel shafts in a helical gear train. It is designed for installations where a low-profile, offset output path helps the gearbox fit alongside a conveyor, process line or other machine structure without placing motor and output on the same axis.
Select the structure before the designation
Confirm the available side space, output-shaft direction, support arrangement and the driven-machine load profile. Parallel-shaft geometry changes the installation conversation, so a model designation must be followed by a mounting and shaft review.
Typical machine context
Typical inquiries include conveyor lines, material-handling drives, packaging systems and process equipment where an offset output layout is useful. The machine-side load, starts and stops, operating environment and access for installation remain part of the selection discussion. If the application has a current reducer, a clear nameplate photo and overall mounting photo are the fastest way to establish the right review path.
- F
- Standard form.
- FA
- Shaft-mounted form.
- FAF
- Flange-mounted form.
- FF
- Flange-oriented variant.

Variant forms
F is the standard form; FA is shaft-mounted; FAF is flange-mounted; FF is the flange-oriented variant. The final mounting form is confirmed against the actual machine interface and not inferred from the family code alone.
Catalogue selection tables by frame
The tables below are generated from the confirmed rows of the HaoRan RSKF catalogue. Each frame section is collapsed by default. Use the power filter to reduce the visible rows inside any open table; it does not alter the catalogue source or make a compatibility decision.
No catalogue rows match these filters. Clear filters to review all captured rows.

Combined units
These rows have a recorded ratio of 300 or higher. They are achieved by combining two gear reducers; they are shown separately so the high-ratio envelope is not represented as a single-unit claim.
No confirmed catalogue rows in this ratio group for this frame.
How the data should be used
How the data should be used
The values are catalogue envelopes and selection rows, not a promise that every configuration will fit every machine. The model designation, mounting form, output shaft, flange, service condition and installed dimensions must be reviewed together. Send the nameplate and installation photos of the existing unit with the driven-machine application before order confirmation.
Request a frame and mounting review
Request a frame and mounting review
Send your nameplate and include the frame designation, driven equipment, operating condition and available mounting information. HaoRan Transmission will confirm the required mounting dimensions before you order.
