Keyway Type Flexible Shaft Coupling Description
DLK7 Keyway Type Flexible Shaft Coupling is a high-precision one-piece metallic spring coupling designed for reliable torque transmission in demanding applications. Featuring zero backlash and a keyway design for secure shaft connection, it effectively absorbs parallel and angular misalignments as well as shaft end-play through its built-in spring mechanism. Made from durable aluminum alloy and stainless steel, the DLK7 coupling ensures smooth bidirectional performance, making it ideal for servo motors, stepper motors, CNC machines, and other precision automation equipment.
DLK7 Series Flexible Shaft Couplings deliver precise, zero-backlash torque transmission with built-in spring action to absorb parallel and angular misalignments as well as shaft end-play. All three types - Keyway, Setscrew, and Clamp - share identical performance characteristics and materials, ensuring smooth bidirectional rotation and high durability. The main difference lies in the shaft connection method: Keyway Type uses a shaft key for secure positioning, Setscrew Type fastens directly with screws, and Clamp Type locks around the shaft with a clamp for easy installation and removal. This allows you to choose the coupling type that best fits your mechanical setup without compromising precision or reliability.

Other Types of DLK7 Couplings
DLK7 Setscrew Type Flexible Shaft Coupling
The Setscrew Type fastens directly onto the shaft with screws, offering easy installation and reliable torque transfer. Suitable for general machinery and applications where moderate precision is sufficient and installation simplicity is preferred.
DLK7 Clamp Type Flexible Shaft Coupling
The Clamp Type secures around the shaft with a clamp, allowing quick installation and removal without special shaft modifications. Perfect for equipment that requires frequent maintenance or flexible shaft connection, while still maintaining zero backlash and smooth bidirectional rotation.
DLK7 Keyway Type Flexible Shaft Coupling
Designed for high-precision applications, the Keyway Type uses a shaft key for secure, slip-free positioning. Ideal for servo motors, stepper motors, and CNC machinery where maximum torque accuracy and zero backlash are required.
