Reliable for Heavy Duty Use

Using this on a high-torque pump application. The BoWex design absorbs vibration effectively, and there is no noise after installation. Highly recommended.

Genuine German Quality

Received the Bo14 coupling exactly as described. The build quality is exceptional, and the nylon gear teeth are perfectly molded. Fits our motor shaft without any issues.

Solid Performance

Great coupling that handles misalignment well. Only giving 4 stars because the packaging was slightly damaged during transit, though the product itself was fine.

Perfect Replacement Part

We needed a specific 20/24 tooth configuration for our conveyor system. This KTR unit was in stock and shipped quickly. Installation was straightforward.

5 FAQ

Q: Does this coupling require lubrication?

A: No, the KTR BoWex nylon gear coupling is maintenance-free and does not require lubrication due to its self-lubricating nylon material.

Q: What is the maximum angular misalignment this unit can handle?

A: The BoWex coupling can typically compensate for angular misalignment up to 3 degrees, depending on the specific size and operating speed.

Q: Is the 1b end configuration standard for all sizes listed?

A: Yes, the '1b' designation refers to the standard hub style with a keyway and set screws, which is consistent across the 14, 19, 24, 20, and 28mm options in this listing.

Q: Can I mix hub sizes, for example, a 14mm bore on one side and 19mm on the other?

A: Yes, the BoWex external gear coupling allows for different hub diameters on each side to connect shafts of varying sizes, provided they fall within the available range.

Q: Do you provide a certificate of origin for this German import?

A: Yes, we can provide a Certificate of Origin upon request at the time of purchase to verify the German manufacturing source.
