Materials and Surface Finish: Belflex™ couplings are made with AISI 321 stainless steel bellows and hubs from 2024 T351 or 7075 T651 aluminum, finished with Type II sulfuric anodizing.

Hardware Specifications: The couplings use heat-treated alloy steel socket head cap screws and forged socket set screws, compliant with ASA and ASTM standards. They operate between -40°F and 200°F, with a maximum speed of 10,000 rpm.

Torque Ratings: Detailed torque ratings are provided for clamp and set screws in both inch and metric units, including seating torque for alloy and stainless steel variants.

Installation Instructions: Key steps include checking shaft misalignment, aligning hubs, tightening screws to recommended torque, and ensuring the coupling is axially relaxed.

Product Features: Belflex™ bellows couplings offer low inertia and high torsional rigidity, suitable for high-performance applications requiring precision and repeatability. They accommodate various misalignments while maintaining low bearing loads.

Warranty and Liability: Ruland guarantees products meet size and material specifications, offering replacement or refund options. Other warranties are disclaimed, and liability is limited to the purchase price.

Product Variants: Various part numbers are listed for clamp and set screw styles, with specifications for bore sizes, outer diameters, lengths, and torque ratings in both inch and metric dimensions.

Overview of Bellows Couplings: Designed for motion control applications, bellows couplings allow flexibility under misalignments while maintaining torsional rigidity, ensuring accurate motion transfer.
