Why choose Ruland?
Made in USA
All products are manufactured in Marlborough, Massachusetts using proprietary in-house processes.
Precision & zero-backlash
Couplings are precision honed for collinear bores and zero-backlash torque transmission in servo systems.
RoHS3 & REACH compliant
Products carry Nypatch anti-vibration coating and meet RoHS3 and REACH environmental standards.
High-speed capability
Designs range from beam couplings to slit couplings rated up to 70,000 RPM.
Product series
Understand each series to find the right fit for your application.
Shaft Collars
One-piece, two-piece, set-screw, and clamp-style collars providing strong, even holding power for shaft positioning and stops.
Rigid Couplings
One-piece and two-piece rigid couplings connecting shafts in precise collinear alignment for high-accuracy servo systems.
Beam Couplings
Single, four, and six-beam couplings offering high misalignment capacity with zero-backlash operation for encoders and light-duty drives.
Bellows Couplings
Anodized aluminum hubs with stainless steel bellows delivering low inertia and high torsional stiffness at speeds up to 10,000 RPM.
Oldham Couplings
Two hubs with a center disk providing excellent parallel misalignment accommodation with zero-backlash operation up to 4,500 RPM.
