Zero backlash performance

We needed a coupling with zero backlash for our precision application, and this delivers. The keyway fits snugly, and the flanges lock together tightly.

Perfect fit for our conveyor system

The 150mm diameter matched our specifications exactly. The bolted connection is very secure, and the keyway alignment was precise. Great quality steel.

Solid construction, heavy duty

This coupling feels incredibly robust. It handles high torque without any vibration issues. Only giving 4 stars because it is quite heavy to install alone.

Good value for money

Does exactly what it says on the tin. The black oxide coating seems durable against rust. Installation was straightforward with standard tools.

Reliable for industrial use

Replaced an old worn-out coupling with this YLD model. The difference in smoothness is night and day. Highly recommend for heavy machinery.

Excellent machining precision

The concave-convex flange design ensures a tight seal and perfect alignment. We have been running it at high speeds for weeks with no wear visible.

5 FAQ

Q: Is this suitable for outdoor applications exposed to rain?

A: While the black oxide coating provides some resistance, we recommend additional greasing or housing protection for prolonged outdoor exposure to prevent corrosion.

Q: What is the maximum bore size this coupling can accommodate?

A: The maximum bore size depends on the specific keyway configuration ordered, but for the standard 150mm OD model, it typically supports bores up to 60mm. Please check the detailed spec sheet for your specific SKU.

Q: What lubrication is required for installation?

A: We recommend applying a standard industrial anti-seize compound on the shaft and a light layer of grease on the mating flange surfaces before assembly.

Q: Can this handle reversible rotation directions?

A: Absolutely. The symmetrical concave-convex design allows for seamless operation in both clockwise and counter-clockwise directions without performance loss.

Q: Are the bolts included with the coupling?

A: Yes, this YLD Coupling comes as a complete kit including all necessary high-tensile bolts and washers for the flange connection.
