Nylon Sleeve Gear Flexible Couplings Overview
Huco's Nylon Sleeve Gear Couplings are designed for flexible and maintenance-free operation. They are suitable for both horizontal and vertical assembly, allowing for easy inspection and adjustment without disassembly. The couplings are directly interchangeable with industry-standard designs.

Double Crowned Tooth Gear Coupling
The double crowned tooth design allows for free axial movement, low friction, and minimal stress during misalignment. It features a large contact area to reduce stress from shaft misalignment and distributes load near the center of the tooth for maximum strength. The design is maintenance-free, requiring no lubrication.

Specifications and Performance
The couplings are available in various sizes, with nominal torque ratings ranging from 85.9 lb.-in. (9.7 Nm) to 3292.5 lb.-in. (372 Nm). They can operate at maximum RPMs from 4000 to 14000, depending on the size. The couplings are designed to handle ambient temperatures between -13°F and 180°F, with heat-stabilized polyamide available for temperatures up to 250°F.

Material and Design
The couplings feature a molded nylon sleeve with high torsional stiffness and steel hubs. They are resistant to dirt, moisture, chemicals, and petroleum products, requiring no lubrication or maintenance. The compact and lightweight design ensures high torque and low inertia, suitable for high-speed applications.

Order Codes and Dimensions
Order codes are provided for pilot hubs, sleeves, and complete couplings. Detailed dimensions and performance characteristics are listed for each size, including bore diameters, fastening methods, and alignment tolerances.
