STF – HB Series – Cam Ring Piston Hydraulic Motors
When your industrial applications demand the absolute maximum in torque and structural resilience, the STF CRM-HB Series stands as the definitive solution. Specifically developed for the most punishing overloaded applications—such as industrial shredders, heavy-duty conveyor belts, and massive hinge heads—this series is engineered to work stably in the harshest environments. Featuring a sophisticated disc flow, radial piston, and inner curve architecture, the CRM-HB series also utilizes a specialized hollow shaft design. This allows for the seamless integration of brakes, tachometers, and auxiliary equipment directly through the motor’s center, drastically simplifying your machine’s overall design and saving critical installation space.
Core Technical Specifications:-
- Component Architecture: Heavy-Duty Cam Ring Piston Motor (Hollow Rotor)
- Model Variations: CRM-HB-280, 400, 560, and 840
- Maximum Operating Pressure: Up to 208 bar
- Extreme Rated Torque Range: 60,000 N.m to 210,000 N.m
- Design Feature: Space-saving Hollow Shaft for accessory integration
Key Features & Engineering Advantages:-
- Massive Output Torque: Delivering a staggering torque range up to 210,000 N.m, this motor is designed to replace complex, high-maintenance combinations of high-speed motors and heavy gearboxes with a single, compact direct-drive unit.
- Hollow Shaft Versatility: The internal hollow-bore design provides a dedicated path for mounting parking brakes, speed sensors, or specialized through-shaft equipment, allowing you to customize the motor to your specific host structure.
- Superior Anti-Shock Capability: Built with a high power-to-mass ratio and a rugged inner-curve structure, the CRM-HB series provides exceptional stability under sudden, violent load spikes common in material shredding and heavy transport.
- Low-Speed Precision: Engineered for "stable-at-stop" performance, maintaining smooth, consistent rotational force at very low speeds, which is essential for heavy-load positioning and controlled conveyor movement.
- Operational Flexibility: Supports a "free-running" mode for coasting conditions and features fully reversible rotation, providing equal strength in both clockwise and counter-clockwise directions.
- Simplified Maintenance: The compact, integrated design reduces the number of wear parts compared to traditional gearbox-driven systems, resulting in higher reliability and faster service intervals.
Ideal Industry Applications:-
The monumental torque and shock-resistant design of the CRM-HB motor make it the mandatory power source for:
- Industrial Shredders & Crushers: Handling the violent, high-torque demands of primary metal, tire, and waste shredding operations.
- Heavy-Duty Mining Conveyors: Driving high-capacity, long-distance belt systems that must start under full-load conditions.
- Large-Scale Marine & Offshore: Powering massive mooring winches, heavy-duty hinge heads for ramp systems, and high-capacity deck machinery.
- Bulk Material Handling: Serving as the primary rotational drive for heavy-duty industrial feeders, bucket wheels, and rotary kilns.
Why Choose the STF CRM-HB Series?
- Eliminate Gearbox Failures: By switching to a direct-drive CRM-HB motor, you remove the weakest link in your drivetrain—the gearbox—drastically reducing the risk of catastrophic mechanical failure.
- Consolidate Your Design: Use the hollow shaft to integrate your braking and sensing systems internally, shrinking the overall footprint of your machinery.
- Built for the Overload: This motor doesn't just "handle" heavy loads; it is specifically designed for environments where overloading is a daily operational reality.
