The S family combines a helical input stage with a worm stage to turn the drive through a right angle. Its structure is useful where the motor cannot sit in line with the driven shaft and where the gearbox layout must turn the transmission path within the machine envelope.
Select the structure before the designation
A worm-stage application needs more than a designation match: the duty cycle, heat conditions, starting load and any back-driving or holding requirement need review with the driven equipment. The inherent self-locking tendency of a worm arrangement is application dependent and is not a substitute for confirming a separate holding or brake requirement.
Variant forms
S is the standard foot-mounted arrangement. SA is shaft-mounted, SAF is flange-mounted, and SF is the flange-oriented arrangement used for the applicable installation. The installation form must be checked with the customer’s equipment drawing.
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.

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.

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.
Typical machine context
Typical inquiries include conveyors, material-handling auxiliaries, compact process machinery and equipment that needs a right-angle motor position. 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.
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.
