BOSTON

Boston Gear is a manufacturer of mechanical power transmission components with a history dating back to the late 19th century. The brand is known for standardized inch and metric gears, speed reducers, bearings, and related drive elements used across industrial machinery. 3G Electric supplies the Boston line globally, with stock including gear racks, miter gears, spur gears, and other power transmission parts. The product families most relevant to plant engineers and maintenance teams include rectangular and square inch gear racks, spiral miter gears, and a broad range of stock gears and assemblies. These components are used to convert rotary motion to linear motion, change shaft direction, and transmit torque in applications such as CNC equipment, packaging lines, conveyors, and valve actuation. Technical buyers will find that Boston gear racks are commonly specified with a 14.5° pressure angle and teeth-per-inch values ranging from 1.91 to 3.82, in steel construction. Available cross-sections include 1/2 in × 3/4 in, 3/4 in × 3/4 in, 5/8 in × 1 in, 3/4 in × 1 1/4 in, 1 1/4 in × 1 1/4 in, and 1 1/2 in × 1 1/2 in, with standard 6 ft lengths. Spiral miter gears in the Boston range include 25-tooth configurations with right-hand and left-hand spirals, intended for right-angle power transmission between intersecting shafts. These miter gears are manufactured to inch-size tooth profiles, which allows for smooth engagement and load distribution in confined spaces. 3G Electric supports the Boston line by maintaining inventory of common part numbers, providing specification data for each SKU, and coordinating logistics for international shipments. The company serves procurement specialists who need to match existing Boston components or specify replacements for aging equipment. Because Boston products are standardized, cross-referencing is often straightforward when original part numbers are available. For engineers evaluating gear racks, the key selection variables are pressure angle, teeth per inch, cross-section, and length. Boston racks are typically supplied in steel, which can be machined or heat-treated depending on the application. Miter gears are selected based on tooth count, spiral direction, and shaft angle. 3G Electric provides access to these specifications so buyers can confirm fit and function before ordering. The Boston brand is not tied to a single industry; its components appear in food processing, material handling, automotive assembly, and energy production. 3G Electric ships Boston products worldwide, with documentation and logistics support for cross-border transactions. For maintenance managers, having a reliable source for standard power transmission parts reduces downtime when a gear or rack fails. The combination of Boston's catalog breadth and 3G Electric's distribution reach allows buyers to source individual components or small batches without minimum-order complications. This profile covers the Boston product families currently listed by 3G Electric, with emphasis on gear racks and miter gears. Additional Boston items such as spur gears, worm gears, and bearings may be available on request. Buyers should refer to specific SKU data for dimensions, pressure angles, and material specifications.

Common Applications

  • CNC and linear motion systems — Boston rectangular gear racks (e.g., L514-6, L515-6) convert rotary motion to precise linear movement.
  • Right-angle drive assemblies — Boston spiral miter gears (HLSK104Y R/L) change shaft direction in compact industrial machinery.
  • Material handling and conveyors — Boston gear racks and pinions provide linear actuation for indexing and positioning mechanisms.
  • Packaging equipment — Boston miter gears transmit torque between intersecting shafts in synchronized drive trains.
  • Valve and damper actuation — Boston gear racks offer manual or motorized linear stroke for flow control devices.
  • Food processing machinery — Boston steel gear racks and miter gears are used in washdown-adjacent drive systems where corrosion resistance is managed through material selection and lubrication.

Frequently asked questions

Common questions about BOSTON from 3G Electric.

What pressure angle do Boston gear racks use?

The Boston gear racks listed by 3G Electric are manufactured with a 14.5° pressure angle. This is a standard inch-system pressure angle used in many industrial linear motion applications. Teeth-per-inch values vary by model, with common options including 1.91, 2.55, 3.18, and 3.82 TPI. The pressure angle affects the shape of the gear tooth and how it meshes with a mating pinion. When replacing a rack, the pressure angle must match the existing pinion to ensure proper contact and load distribution. Buyers should confirm the pressure angle on both the rack and pinion before ordering.

What sizes of Boston rectangular gear racks does 3G Electric supply?

3G Electric supplies Boston rectangular gear racks in several cross-sections, including 1/2 in × 3/4 in, 3/4 in × 3/4 in, 5/8 in × 1 in, 3/4 in × 1 1/4 in, 1 1/4 in × 1 1/4 in, and 1 1/2 in × 1 1/2 in. Standard length for these racks is 6 ft. Teeth-per-inch options range from 1.91 to 3.82. The racks are made of steel. Model numbers include L514-6, L515-6, L516-6, L518-6, L519-6, and L521-6. Availability can vary, so confirm current stock with 3G Electric when specifying.

What are Boston spiral miter gears used for?

Boston spiral miter gears are used in right-angle power transmission systems to change shaft direction between intersecting shafts. The spiral tooth form provides smoother engagement and quieter operation compared to straight miter gears. The models listed by 3G Electric have 25 teeth and are available with right-hand or left-hand spiral. They are designed for inch-size tooth profiles. Typical applications include industrial machinery where space constraints require a compact right-angle drive. When selecting a miter gear, the spiral direction must be specified to match the mating gear and the desired direction of rotation.

Are Boston gear racks made of steel?

Yes, the Boston gear racks supplied by 3G Electric are steel. Steel construction provides strength and wear resistance for linear motion applications. Depending on the specific model, the steel may be suitable for machining or heat treatment if additional hardness is required. The racks are not pre-hardened unless specified. For high-load or high-cycle applications, buyers should review the material condition and consider whether a hardened rack or pinion is needed. 3G Electric can provide material and dimensional data for each SKU to assist with selection.

How does 3G Electric support Boston product sourcing?

3G Electric maintains inventory of common Boston part numbers, including gear racks and miter gears, and provides specification data such as pressure angle, teeth per inch, dimensions, and material. The company coordinates international logistics for buyers who need Boston components shipped outside their home region. For procurement specialists, 3G Electric can assist with cross-referencing original part numbers and confirming availability. Because Boston products are standardized, matching existing components is often possible when the original model or SKU is known. 3G Electric does not manufacture Boston products; it distributes them as part of its industrial equipment portfolio.
