Rigid shaft coupling for precise alignment

This one-piece clamp coupling joins two 15 mm shafts without a keyway. It is machined from 303 stainless steel bar stock and rated to 1400 in-lbs of torque. The design targets applications where alignment is critical, backlash is unacceptable and flexibility is not required. Typical uses include timing, joining or aligning shafts at lower speeds and torque levels.

One-piece clamp with four socket capscrews

The coupling measures 34 mm outside diameter, 50 mm overall length and 39.40 mm clearance diameter. Four M5 vibration-resistant socket capscrews provide extra holding power for higher load applications without marring the shafts. A bright finish protects the stainless surface. The single-piece construction simplifies installation when shafts can be slid together during assembly.

Fixed connection limits misalignment tolerance

Because the coupling is rigid, it cannot accommodate angular, parallel or axial misalignment between shafts. Buyers who need to absorb vibration, shock loads or thermal expansion should select a flexible alternative. The 1400 in-lbs torque ceiling also restricts use in high-torque drivelines. The 15 mm bore size fixes compatibility to matching shaft diameters only.

Questions about this item

What torque does the one-piece clamp coupling rated for 1400 in.-lbs. actually transmit?

The 303 stainless steel coupling transmits up to 1400 in.-lbs. of torque when the four M5 socket capscrews are tightened to the manufacturer's recommended seating torque.

Will the 34 mm outside diameter and 39.40 mm clearance diameter fit inside my machine envelope?

The coupling measures 34 mm across the barrel and needs a 39.40 mm diametral clearance for the clamp screws, so verify that your housing bore exceeds 39.40 mm before ordering.

How do I install the rigid coupling on two 15 mm shafts without a keyway?

Slide the 50 mm long barrel onto both shafts, align them, then tighten the four M5 capscrews in a cross pattern to 3.5 N·m; the common error is tightening one screw fully before the others, which can cock the clamp.
