Highly Responsive Couplings for Semiconductor and Solar Applications
Bellows couplings offer a high degree of accuracy and repeatability for solar and semiconductor applications such as test and measurement, inspection, wafer handling, leaning, packaging, and solar panel production.
The combination of anodized aluminum hubs with a stainless steel bellows results in a lightweight, low inertia coupling that remains stiff under torsional loads. A balanced design reduces vibration for high speed applications up to 10,000 RPM. Bellows couplings are able to accommodate all types of misalignment with low bearing loads due the thin stainless steel walls of the bellows. They are zero backlash and have no moving parts allowing for a long, maintenance free life making them ideal for high end stepper or servo driven systems. Ruland offers clamp or set screw style bellows couplings with straight, stepped, or inch to metric bores ranging from 3mm to 25mm and 1/8” to 1”. Stainless steel hubs, keyways, and other custom design features are available by special order. Ruland Manufacturing Co., Inc. was established in 1937 as a manufacturer of precision components. Ruland’s focus for the past 40 years has been on high performing shaft collars and couplings. All metallic Ruland products are made in its Marlborough Massachusetts factory. The complete line of products includes shaft collars and rigid couplings, and a full line of zero backlash motion control couplings: beam couplings, bellows couplings, oldham couplings, disc couplings and curved jaw couplings.
