Boston Gear F842B-28K-B5 Speed Reducer

Boston Gear F842B-28K-B5-M1 is an inline helical speed reducer from the 800 Series that packs a 28:1 reduction into a compact 56C frame with a C-face flange, designed for direct coupling to standard 56C motors and flexible installation in space‑constrained automation setups. This variant is commonly cataloged as F842B-28K-B5-M1 and is rated for up to 1 hp input, capable of delivering up to 994 in-lb of output torque, with an approximate output speed near 62 RPM when driven from a typical 1,800 RPM motor. The mounting and orientation are versatile thanks to the C-face flange and 56C frame, with documentation across retailers verifying the M1 suffix and confirming installation options including any‑angle mounting. As part of Boston Gear’s inline helical gear drives, the F842B-28K-B5-M1 family emphasizes smooth operation and a compact footprint for a range of industrial applications requiring reliable torque reduction.
