Ruland BC16-6-6-A 2024 or 7075 Aluminum Hubs Bellows Coupling, Clamp Style, 0.375″ x 0.375″ Bores, 1.000″ OD

Description

Product Overview

The Ruland BC16-6-6-A 2024 aluminum bellows coupling is engineered for demanding power transmission environments where precision, durability, and minimal vibration are paramount. Constructed from high‑strength 2024 aluminum alloy, the coupling offers a balanced design that reduces resonant frequencies while delivering zero‑backlash operation. Its thin‑walled bellows provide exceptional flexibility, allowing angular misalignment up to 2 degrees and axial movement while maintaining high torsional stiffness. The 0.375″ x 0.375″ bore and 1.000″ outer diameter fit standard shafts and hubs, making installation straightforward. Tested beyond DIN 912 12.9 standards, the coupling can handle torque loads well above typical industry requirements, ensuring reliable performance at speeds up to 10,000 RPM.

Usage

This coupling excels in a variety of industrial and scientific applications. It is ideal for CNC machines, robotic arms, high‑speed spindles, and precision instrumentation where repeatable positioning is critical. The robust aluminum construction tolerates harsh environments, including exposure to oils and coolants, while remaining RoHS3 and REACH compliant. Engineers and technicians appreciate the ease of alignment and the ability to absorb shock loads without compromising accuracy. Whether used in aerospace component assembly lines, medical device manufacturing, or automated packaging equipment, the BC16‑6‑6‑A ensures smooth power transfer and extended service intervals.

FAQ

What shaft sizes are compatible with this coupling?

The BC16‑6‑6‑A features 0.375″ (9.5 mm) bore dimensions on both ends, fitting standard shafts that match this size. The 1.000″ outer diameter allows it to mount on typical hubs used in industrial equipment.

Can the coupling handle misalignment?

Yes. The flexible bellows accommodate angular misalignment up to 2°, axial displacement of 0.020″ (0.5 mm), and radial offset of 0.010″ (0.25 mm) without compromising torque transmission.

Is this coupling suitable for high‑temperature environments?

The 2024 aluminum alloy maintains structural integrity up to 250 °F (121 °C). For applications exceeding this temperature, Ruland offers alternative materials such as stainless‑steel or composite couplings.

How does the coupling compare to steel alternatives?

Aluminum provides a superior strength‑to‑weight ratio, reducing rotating mass and inertia, which improves acceleration and reduces bearing wear. Additionally, aluminum’s thermal conductivity helps dissipate heat generated at high speeds.

What is the warranty period?

Ruland offers a limited one‑year warranty covering material defects and workmanship, backed by our technical support team for installation and performance queries.
