Disc Couplings for Highly Accurate Systems

Ruland offers both single and double disc style couplings for highly accurate systems found in industries such as test and measurement, medical, semiconductor, solar, and liquid handling. Disc couplings have low inertia and are torsionally stiff making them suitable for precise zero-backlash systems with speeds up to 10,000 rpm. Ruland single disc coupling, clamp style,

Developments In Precision Positioning Stages with High Speed Range

High-precision linear stages used for applications such as surface measurement in life sciences, semiconductor manufacturing and other industries often require two distinctly different modes of motion. A rapid mode usually is needed to change locations quickly in the workspace, which might then be followed by very slow motion for finer focusing and resolution. The traditional

Grease-free Bearings Eliminate Maintenance in Lab Equipment

A manufacturer of scientific instruments and lab equipment recently replaced its recirculating ball bearings with DryLin R linear bearings because the recirculating units required frequent maintenance and re-lubrication — time consuming and expensive processes. The new bearings are dry running and do not require external oils or greases. This feature is especially important for medical

Ball Screw Helps Device Simulate Breathing Conditions

Ventilator management is paramount to intensive care, but clinical training may not provide medical students with adequate experience in this area. Hands-on work in adjusting the ventilator to changing patient parameters in real time is invaluable to understanding the process. To aid medical educational programs, Stefan Frembgen, president, IngMar Medical, a company that specializes in
