Quantis®
Modular Gear Reducer
Engineered for reliability and efficiency with an industry-leading sealing system for premier performance in any type of environment
Quantis is a leading modular gear reducer for industrial applications, designed for reliability and efficiency with an industry-leading sealing system. True to the Dodge standard, 100 percent of all units are quality tested before shipment.
The Quantis family of products offers customers three types of gear arrangements: in-line helical (ILH), motorized shaft mount (MSM), and right-angle helical bevel (RHB). All three gear types are available with integrated- or flange mounted motors and are dimensionally interchangeable with major global competitors.
Additionally, Quantis is offered in E-Z Kleen® and FoodSafe™ options to tackle the toughest washdown environments for superior performance in food and beverage applications.

Frequently asked questions (FAQs)
How do I replace an existing gearbox with a Quantis gear reducer?
Quantis gear reducers are engineered to support direct retrofit and drop-in replacement of other manufacturers’ units when a confirmed interchange is available. Use PT Wizard to configure your application and verify critical fit details including shaft height, mounting footprint, bore size, and torque rating. When a Quantis reducer is confirmed as a drop-in interchange, the First-Fit Promise guarantees it will match existing shaft centers and mounting interfaces, allowing installation to be completed without modifying your equipment. A Dodge Sales Engineer can review your selection and confirm the interchange before you order.

What are the approved mounting positions for Quantis reducers?
Quantis reducers support horizontal, vertical, and incline mounting positions. Each orientation requires correct placement of breathers and drain plugs to maintain proper oil lubrication. Incorrect installation can cause oil to shift away from bearings and gearing, resulting in overheating and premature wear. Detailed mounting position diagrams and oil level guidance are available in the Quantis installation and maintenance manual and the product catalog. Always reference these resources before startup.

What shaft attachment options are available for Quantis reducers?
Quantis reducers are available with four shaft attachment options to match different installation and maintenance requirements:
- Twin-tapered bushings provide a concentric shaft grip for reliable torque transmission and can be removed without damaging the shaft, supporting lower total cost of ownership
- Straight hollow bore offers a simple, cost-effective shaft-mounted connection for standard applications
- Q-Loc keyless bushings allow mounting without keys, helping prevent shaft damage and reduce installation time
- Solid shaft provides a direct connection for applications using couplings or external components
Each option is designed to simplify installation based on shaft size, load, and service conditions.

What mounting hardware and accessories are available for Quantis reducers?
Quantis reducers can be configured with mounting and service accessories to support proper installation and torque control. Common options include:
- Banjo torque arms manage reaction torque and maintain shaft alignment
- Torque-arm brackets and tie rod kits secure the torque arm to the mounting frame and control movement during startup and load shifts
- Spring-loaded breathers regulate internal pressure to prevent oil leakage and protect seals
- Washdown and corrosion-resistant options include stainless steel hardware, epoxy-coated housings, and enhanced sealing for demanding environments
All accessories are engineered and rated for the corresponding reducer frame to ensure correct fit, alignment, and load control in service.

Where can I find CAD models for Quantis reducers?
2D and 3D CAD models for Quantis reducers are available through the Dodge CAD portal. Each model includes dimensional, shaft, and mounting data to help confirm fit and alignment during design or retrofit planning. Files are available in multiple formats for direct use in most CAD and plant layout systems.
