Simplify designs with 4-point contact ball bearings

Four-point contact ball bearings can handle radial, thrust and moment loads simultaneously, saving space, weight and cost by eliminating the need for a second bearing. They are generally used for slow to moderate-speed applications, or where oscillatory movement is sufficient to cause the balls to make one or more revolutions. A new white paper from Kaydon Bearings explains how four-point contact bearings work, their advantages, and design considerations when using them.

The Significance of Critical Cleaning for Solar Module Fabrication

With increased governmental commitments to support renewable energy initiatives, winners and losers in solar module fabrication will be determined more quickly and by a variety of factors. One factor will be the elimination of defects to increase yields in the manufacturing process. Critical cleaning of substrates and superstrates is an essential component in achieving an optimal solar module fabrication process which reduces the cost per watt. Depending on the material being cleaned and the cleaning process employed, various Alconox products, including ALCONOX, DETOJET, LIQUINOX, CITRANOX and CITRAJET, have already been selected by major manufacturers as the critical cleaners of choice to reduce or eliminate manufacturing defects in solar module fabrication and are being employed in additional emerging processes.

Key Procedures and Aqueous Cleaning Agents for Metal and Electronic Component Cleaning

Effective use of aqueous cleaners for electronics and metals hinges on the orchestration of basic variables of cleaning agents and procedures. The terms precision or critical cleaning apply whenever residue can cause a failure in the performance or function of the surface being cleaned. In general industry this includes electronic component cleaning, and surface preparation of metals prior to coating or bonding. Current practice for critical cleaning includes the use of volatile solvents, corrosive chemicals, and aqueous detergents. In today’ hazard-sensitive workplace, however, many companies are re-examining their use of volatile-solvent and corrosive-chemical cleaners. By using the right aqueous cleaning technologies now, it’ possible to minimize hazards without sacrificing critical cleaning performance. Many aqueous cleaners now offer cleaning performance comparable to - or better than solvent cleaning systems.

Re-Inventing the Rotary Encoder: The No-Compromise IXARC from POSITAL

Designers of motion control or industrial automation systems who need to measure the rotation of shafts or other mechanical components have had two types of rotary encoders to choose from. Encoders based on optical measurement techniques can provide high levels of precision and dynamic response, but are relatively bulky and can be unreliable in damp or dusty conditions. Magnetic encoders are typically more compact and rugged, but until now, have offered lower levels of precision and dynamic response. POSITAL has eliminated the need for compromise by developing a new generation of magnetic absolute and incremental encoders that match the performance of optical shaft-mounted encoders in all but the most demanding applications. The new magnetic IXARC encoders are compact, accurate, fast and tough enough for challenging environmental conditions.

When Wire Feedthroughs Make Sense

Engineers who work with pressure and vacuum chambers usually reach for off-the-shelf sealed bulkhead connectors when they need to pass power and signal wires through the chamber wall. And while these connectors may seem like the best or only way to breach the chamber walls, they can actually drive cost, impose unnecessary mechanical design constraints and trigger electrical problems. So what’s the alternative? Wire feedthroughs hermetically sealed with epoxy.
