Dimensional continuity
Legacy reducer footprints are cross-checked against mounting base, shaft height, and seal orientation to reduce field rework during replacement programs.
AGMA-rated reducer engineering
Boston Gear reducers for ISO 6336 load cases and AGMA Q10 gearing
0.5-200 HP · AGMA Q10 · ISO 9001:2015 · stocked reducer families
Boston Gear supports OEM and MRO teams with right-angle worm reducers, helical-bevel units, open gearing, couplings, and motorized packages built around traceable engineering documentation rather than generic catalog copy.
Specification map
Reducer families documented by ratio, service factor, and mounting envelope
| Power envelope | 0.5-200 HP application screening with service factor review |
|---|---|
| Ratio review | Common low-speed ratios documented with input rpm, thermal rating, and mounting position |
| Gear quality anchor | AGMA Q10 inspection language for cut gear components and open gearing support |
Spur, helical, bevel, and miter gear requests are organized by bore, face width, pitch, material callout, and inspection level so drawings can be checked before machining or replacement sourcing.
Engineering support checks NEMA frame fit, shaft diameter, keyway, expected radial load, bearing L10 target, and VFD duty where reducers are paired with industrial motors.
Why engineers keep the catalog open
Practical details that shorten reducer selection
Stock-aware support
Warehouse availability is considered with thermal rating and service factor, helping maintenance teams avoid selecting a stocked part that fails the duty cycle.
AGMA language
Gear quality, backlash, and lubrication notes are written in terms that purchasing, plant engineering, and outside machine builders can all verify.
Application notes
Conveyor starts per hour, washdown exposure, shock loading, and motor control method are documented before a quote becomes a build instruction.

Engineering FAQ
Answers before the first RFQ
Can Boston Gear reducers replace older field units?
Yes, but the review starts with nameplate, ratio, mounting base, shaft size, service factor, oil type, and duty cycle. A direct dimensional fit still needs thermal and radial load confirmation.
What data is needed for gear component quotes?
Submit pitch, pressure angle, tooth count, bore, keyway, material, heat treatment, face width, and the AGMA or ISO quality class required by the assembly drawing.
How are motorized reducer packages screened?
The team checks NEMA frame, hp or kW, input rpm, VFD duty, enclosure, expected starts per hour, and ambient temperature before recommending a package.
Do stocked units still need an engineer review?
For plant-down replacement, stock is useful. For OEM build programs, Boston Gear still reviews ratio, SF, L10 bearing expectation, and lubrication interval before release.
Need a reducer selection checked against torque, rpm, and duty cycle?
Send your application note and the engineering desk will respond with a datasheet path, CAD request option, and the next question needed for a reliable quote.
