Double Crowned Tooth Gear Coupling
Double crowned tooth design provides free axial movement, low friction, and minimum stress during misalignment. Designs are available with up to 9.5mm axial travel.
Large contact area to provide low contact pressure and to reduce the stress of shaft misalignment.
Load distributed near the center of the tooth for maximum strength.
Low friction for a smooth flow of power without the need for lubrication — maintenance-free.
Free axial movement of the coupling parts to compensate for shaft thermal changes and future alignment problems.
Nylon Sleeves, Steel Hubs
Molded nylon sleeve with high torsional stiffness, free from any internal frictional losses or heat build-up. A torsionally stiff coupling with minimum backlash.
Nylon and steel components allow high ambient temperature operation without lubrication or maintenance. Continuous operating ambients in the ranges between (-) 25°C and (+) 82°C. Heat-stabilized polyamide available for temperatures up to (+) 121°C.
Nylon sleeves resistant to dirt, moisture, most chemicals, and petroleum products. No lubrication, seals or retainers to maintain. Easy clean-up and visual inspection.
Compact and lightweight design with high torque and low inertia. Minimum shaft gap for close-coupled applications.
Precision molded concentric sleeve and hubs for high-speed applications. No bolts, pins, flanges, or protrusions to affect balance or safety. Smooth exterior surface.
Blind Assembly
Suitable for assembly in both horizontal and vertical positions. Blind assembly with slip-together components for easy inspection and adjustment without disassembly.
