The K family uses a helical-bevel gear train to transfer power through a right angle. The bevel stage makes it suited to machines that need a perpendicular motor-to-output layout while retaining the character of a hardened-tooth helical transmission.
Select the structure before the designation
Selection begins with the perpendicular shaft arrangement, output direction, driven load and mounting support. The designation establishes the product family, but shaft, flange and housing dimensions require a drawing or installed-unit review before a replacement is confirmed.
Typical machine context
Typical inquiries include conveyors, bucket elevators, mixers, hoists and heavier process drives that require a right-angle arrangement. 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.

Variant forms
K is the standard arrangement; KA identifies shaft-mounted use; KAF and KF cover flange-oriented variants; KH identifies the hollow-shaft form. These names are an enquiry starting point, not a dimensional interchangeability claim.
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.

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.
