What is a beam coupling?
A beam coupling (also known as a helical coupling) is a flexible shaft coupling manufactured from a single piece of material, typically aluminium or stainless steel. A spiral or helical slot is machined into the body of the coupling, forming a “beam” structure that provides flexibility.
A typical beam coupling offers:
Single-piece construction
Helically cut beam section
Bores to suit plain, keyed or clamping shaft connections
The helical beam allows the coupling to transmit torque while accommodating angular, parallel and axial misalignment, as well as compensating for shaft end-play in many precision applications.
Typical applications
Beam couplings are commonly used in:
- Servo and stepper motor drives
- Encoders and feedback devices
- Lead screw and ball screw drives
- Small pumps and instrumentation
- Robotics, automation and pick-and-place systems
- General motion control and light-duty power transmission
Where accurate positioning, low inertia and compact size are important, beam couplings are often the preferred choice.
Beam Couplings FAQs
Are beam couplings backlash-free?
Yes, beam couplings are designed as single-piece couplings and are generally considered backlash-free, making them suitable for many precision positioning and motion control applications.
Are beam couplings suitable for high-torque applications?
Beam couplings are typically used in low to moderate torque applications, especially in motion control. For higher torque or heavy-duty power transmission, other coupling types such as disc, gear or elastomeric couplings are usually more suitable.
