®Gearbox Comparison
Side-by-side comparisons between the R, F, K and S modular geared motor series and other common gearbox topologies. Use these references to narrow the selection before requesting a quote.
Helical-Bevel vs Helical-Worm Gearbox
Helical-bevel and helical-worm gearboxes can both provide right-angle output, but they should not be treated as interchangeable architectures.
Read comparison →How to Choose Between R, F, K and S Gearboxes
R, F, K and S are best understood as four mechanical layout families rather than four levels of the same gearbox.
Read comparison →Inline vs Parallel-Shaft vs Right-Angle Gearboxes
The most efficient way to narrow an industrial gear unit family is to start with shaft arrangement: inline, parallel-shaft or right-angle.
Read comparison →K Series vs S Series Gearbox
K and S are both right-angle families, but they use different transmission architectures. K uses a helical-bevel layout and extends into a much higher reference torque range.
Read comparison →R Series vs F Series Gearbox
R and F both use helical gearing, but the machine layout is different. R is intended for inline or near-inline arrangements, while F is designed around a parallel-shaft layout.
Read comparison →R Series vs K Series Gearbox
R and K solve different shaft-layout problems. R is an inline/near-inline helical unit; K is a right-angle helical-bevel unit.
