Boston Gear 309A-30-C Industrial Gear Reducer

Boston Gear 309A-30-C Industrial Gear Reducer is a compact worm-gear speed reducer in Boston Gear’s 309A/309B sub-fractional horsepower family, designed for light-to-moderate industrial drives. It accepts 1750 RPM input and provides a 30:1 reduction, yielding an output speed of roughly 58 RPM at full speed, with a modest 0.100 HP input rating. Available in A-base or B-base configurations, these units support multiple mounting options to suit space-constrained installations. They are pre-lubricated for life with Klubersynth UH1 synthetic oil and rated for ambient temperatures from -30°F to 225°F (-34°C to 107°C), making them suitable for typical shop-floor environments. The 309A family is produced in standard and variant catalog numbers to match specific shaft, base, and mounting configurations, offering reliable torque multiplication in compact footprints for conveyors, packaging lines, and automation assemblies where precise speed control and compact size matter. Exact torque, shaft styles, and mounting details vary by catalog number, so consult the official Boston Gear product literature for the precise specification for your chosen configuration.
