Ruland Flexible Coupling Flector Acetal Material 19.1 mm Size Torque 2.25Nm OD12/19-AT

Ruland OD12/19-AT Flexible Coupling Flector is manufactured using acetal material with a precision size of 19.1 mm and offers a torque rating of 2.25Nm. This coupling is engineered for efficient mechanical power transmission in industrial applications requiring precise alignment and vibration damping.

The coupling accommodates slight misalignments with angular misalignment tolerance up to 0.5°, axial misalignment of 0.1mm, and parallel misalignment of 0.2mm. Its length is exactly 19.1 mm, designed to suit compact mechanical assemblies.

Torque transmission is enhanced by the combination of nylon vibration-damping discs and backlash-free acetal discs, making this coupling suitable for applications demanding zero backlash and higher torque capacity. The resilient nylon discs help reduce noise and vibration during operation.

Ruland’s Oldham style couplings in this series are ideal for motion control systems, especially those using stepper or servo motors, where electrical isolation and low inertia are crucial. High-speed applications benefit from their design that maintains precision while accommodating minor shaft misalignments.

The coupling hubs are anodised aluminium secured by set screws; 13mm and 19mm hubs use one set screw each, while larger hub sizes have two set screws spaced 90° apart, ensuring secure shaft connection.

This product is manufactured in the United States, reflecting strict quality standards and reliability for industrial, manufacturing, robotics, and automation use cases. Constructed from high-quality acetal for durability and low friction.

Torque rating of 2.25Nm suitable for controlled power transmission. Compatible with shafts secured by set screws on anodised aluminium hubs. Allows misalignment tolerance: 0.5° angular, 0.1mm axial, and 0.2mm parallel. Length of coupling is 19.1 mm matching precision mechanical demands.
