Starflex ALS Keyway Model datasheets

Product catalog summary

Specifications:
The STARFLEX ALS R series jaw couplings are designed for various torque and misalignment specifications. The models range from ALS-014-R to ALS-105-R, with nominal torque values from 2 N·m to 525 N·m and maximum torque values from 4 N·m to 1050 N·m. They accommodate parallel misalignment of 0.10 mm to 0.36 mm, angular misalignment of 1°, and axial misalignment from 0 to +2.0 mm. The maximum rotation speed varies from 4500 min-1 to 34100 min-1, with static torsional stiffness and radial stiffness values provided for each model. The moment of inertia and mass are specified for the maximum bore diameter.

Dimensions:
The dimensions for each model include minimum and maximum bore diameters, outer diameter (D), length (L), and other critical measurements such as L1, L2, E, S, and C. These dimensions are crucial for ensuring compatibility with specific applications.

Standard Bore Diameter:
The datasheet lists standard bore diameters for each model, indicating which diameters are supported as standard. Bore diameters ø11 and below have no keyway, while ø12 and above can be processed for various JIS standards and motor standards.

Ordering Information:
To place an order, specify bore diameter, size, and element type. The element types include R (hardness 97, tight-fit), Y (hardness 90, tight-fit), and B (hardness 97, loose-fit). The material is aluminum.

Additional Notes:
Higher RPMs are possible with balancing, and stiffness values are measured at 20 ℃. Set screws are included with the product, and specific set screw sizes are provided for each model.
