Lightweight and strong
Aluminum holds up well under stress. I use this for a custom lead screw mechanism on my RC winch project. No signs of wear after several runs.

Exact specifications
Matched my lead screw and motor shaft perfectly. The LK5 clamp type makes installation and removal very easy for maintenance.

Perfect for my 1/5 scale build
This coupling fits perfectly between my high-torque servo and the steering linkage. The aluminum is lightweight but feels very durable. Zero backlash noticed during operation.

Good quality
The coupling itself is excellent. Only giving 4 stars because the set screws were slightly tight to thread initially, but once installed, it holds well.

Zero backlash
No play in the steering system after installing this. The disc stack allows for slight misalignment without vibrating. Highly recommend for competitive RC setups.
Q: Is the disc flexible enough for angular misalignment?
A: Yes, the elastic disc stack accommodates slight angular and parallel misalignment effectively.
Q: Does this fit 4mm shafts?
A: No, this specific model is designed for 5mm bores. Please check our store for 4mm variants.
Q: Are set screws included in the package?
A: Yes, all necessary set screws and an Allen key are included for immediate installation.
Q: Can I use this outdoors in wet conditions?
A: Yes, the aluminum alloy has good corrosion resistance, but we recommend drying it after exposure to water.
Q: What is the return policy if it doesn't fit?
A: We offer a 30-day return policy for unused items in original packaging.
