Product catalog summary

Overview: The document provides detailed specifications and descriptions of various coupling models, specifically focusing on jaw couplings under the AL series. It includes information on electromagnetic clutches, brakes, and torque limiters.

Specifications: The jaw couplings, particularly the SPRFLEX models, are designed with a buffer material (spider) between two hubs made of aluminum alloy. They are suitable for applications involving pumps, fans, and textile machinery. The maximum nominal torque is 50 N·m, with operating temperatures ranging from -20°C to 80°C.

Materials and Structure: The spider is made of NBR (Nitrile rubber), providing high flexibility and damping. The hub is constructed from aluminum alloy, and the hexagon head set screw is made from alloy steel with a black coating finish.

Dimensions and Models: The document lists various models (AL-035 to AL-110) with specific dimensions, torque capacities, and rotational speeds. For example, the AL-035 model has a nominal torque of 0.5 N·m and a maximum rotation speed of 18,000 min-1.

Ordering Information: The document provides guidelines on how to place an order, including model selection based on torque, misalignment, and rotational speed requirements. It also details bore specifications compliant with JIS standards and motor standards.

Additional Notes: The document includes tables with detailed measurements for bore diameters, keyway dimensions, and set screw positions. It also notes that higher RPMs are possible with balancing and specifies tolerances for different models.
