Rigid Couplings with Step Bores come in metric sizes.

Press Release Summary:

Suited for equipment manufacturers designing precision servo driven systems or shaft-to-shaft connections, metric rigid couplings with step bores are available in 1- and 2-piece clamp styles with or without keyways. Rigid coupling hardware features Nypatch coating to resist vibration and maintain holding power. Available from 3–50 mm, these RoHS2- and REACH-compliant products are made from 1215 lead-free steel or 303 stainless steel.


Original Press Release:

Metric Rigid Couplings with Step Bores

Marlborough, MA.  Ruland has expanded its line of rigid couplings to include metric sizes with step bores. This gives equipment manufacturers designing precision servo driven systems or shaft-to-shaft connections a wider range of standard in-stock products to choose from. The couplings are available in one- and two-piece clamp styles with or without keyways for superior fit and holding power.

Ruland supplies rigid coupling hardware with a proprietary coating called Nypatch to resist vibration and maintain holding power. Nypatch is applied 360 degrees around several threads of the socket head cap screws to prevent them from loosening under vibration, causing a reduction or loss of torque transmission during operation. It also provides for even seating of the screw, repeated installations and prevents galling. All metric hardware tests beyond DIN 912 standards for maximum torque capabilities.

Clamp type rigid couplings wrap evenly around the shaft to provide high torsional holding power without damage to the shaft caused by set screws. Two-piece clamp styles have a balanced design with opposing screws for reduced vibration and higher speed capabilities. They have the additional benefit of being able to come apart completely for in-place servicing without the need to remove additional components.

Metric rigid couplings are offered in sizes ranging from 3 mm to 50 mm. They are manufactured from bar stock in Ruland’s factory in Marlborough, Massachusetts, and are RoHS2 and REACH compliant. The Ruland name is stamped on each rigid coupling for ease of identification. Rigid couplings are made from 1215 lead-free steel or 303 stainless steel sourced from carefully selected North American mills to ensure product consistency.

Established in 1937, Ruland focuses on the design and manufacture of high performing shaft collars and couplings. All products are carefully manufactured in Ruland’s factory in Marlborough, Massachusetts, under strict controls using proprietary processes. 3D CAD files, full product specifications, and additional technical information are available at www.ruland.com.
