Product Overview: The FF 3525 One-Way Freewheel Clutch
The FF 3525 is a high-precision, sprag-type freewheel clutch designed for press-fit installation into machine components. With a bore diameter of 25mm, an outer diameter of 35mm, and a width of 12mm, this compact unit provides reliable one-way torque transmission. It is engineered to engage and transmit torque in one direction of rotation and freewheel with minimal drag in the opposite direction. This functionality is essential for indexing, backstopping, and overrunning applications in a wide range of industrial machinery.
As a key component in our One Way Lock Bearings collection, the FF 3525 is manufactured from high-quality hardened bearing steel to ensure durability and a long service life. Its simple yet effective design allows for easy integration, making it a preferred choice for engineers seeking to control rotational direction and prevent reverse motion in their systems.
Key Features of the FF 3525
- Unidirectional Operation: Allows torque transmission in one direction while providing a near-frictionless overrun in the other.
- Sprag-Type Design: Utilizes precision-formed sprags for instant engagement and positive locking with no backlash.
- Compact and Lightweight: Its small cross-section allows for space-saving designs without compromising torque capacity.
- Press-Fit Installation: Designed for a simple press-fit into a prepared housing, simplifying the assembly process.
- High-Quality Materials: Constructed from hardened alloy steel for excellent wear resistance and reliability.
- Versatile Functionality: Can be used for indexing, backstopping, or overrunning clutch applications.
Common Applications
- Conveyor Systems: Used as a backstop to prevent loaded conveyors from rolling backward in case of a drive failure.
- Printing Presses: Enables precise paper feeding and indexing operations.
- Packaging Machinery: Facilitates intermittent motion for sealing, cutting, and labeling processes.
- Textile Machinery: Used in looms and knitting machines for controlled fabric advancement.
- Industrial Fans and Pumps: Prevents reverse rotation which could damage the motor or system components.
- Exercise Equipment: Commonly found in stationary bikes and elliptical trainers to provide resistance in one direction.
- Starter Motors: Acts as an overrunning clutch to disengage the starter from the engine once it starts.
Benefits of Using the FF 3525
- Enhanced Machine Safety: The backstopping function prevents uncontrolled reverse movement, protecting both equipment and operators.
- Improved Process Precision: Ideal for indexing applications that require accurate, repeatable intermittent motion.
- Increased Equipment Lifespan: Protects drivetrains from the shock loads and damage associated with reverse torque.
- Simplified Design: Offers a straightforward mechanical solution for controlling rotational direction, reducing the need for complex electronic controls.
- High Torque Density: Provides substantial torque transmission capability relative to its compact size.
- Reliable and Low-Maintenance: Engineered for long-term performance with minimal maintenance requirements.
