Product Description

The DAYTON Rigid Shaft Coupling is a one-piece rigid shaft coupling with a 7/8 in bore diameter for both shafts, featuring same bore dimensions. It is designed for round shaft types and is constructed in inch measurements. This coupling does not include a keyway.

Frequently Asked Questions

What is the DAYTON Rigid Shaft Coupling used for?

The DAYTON Rigid Shaft Coupling connects two shafts of equal diameter (7/8 in) in applications requiring precise alignment and torque transmission without misalignment. It is commonly used in industrial machinery, conveyors, and power transmission systems where shaft ends must be locked together.

What are the specifications of the DAYTON rigid shaft coupling?

The DAYTON is a one-piece rigid shaft coupling with 7/8 in bore diameter on both ends (same bore dimensions). It is designed for round shafts, uses inch measurements, and does not include a keyway. The coupling provides a solid, non-flexible connection for inline shaft applications.

Where to buy the DAYTON rigid shaft coupling worldwide?

3G Electric supplies the DAYTON rigid shaft coupling to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your location. Contact us for pricing and lead time on this coupling.

How to install a DAYTON rigid shaft coupling without a keyway?

Installation of a keyless DAYTON rigid shaft coupling requires clean, burr-free shaft ends. Slide the coupling over one shaft, align the second shaft, then center the coupling over the joint. Tighten set screws (if provided) evenly to manufacturer torque specs. Ensure shafts are aligned within 0.002 in to prevent binding.
