Brass vs. stainless steel inserts: Harder isn't always beter
Plastics and other soft materials often rely on threaded metal inserts to holdfasteners and reinforce joints. Though stainless steel may be appropriate sometimes, brass can satisfy most insert-performance requirements and save money at the same time.

Backyard wind turbines
Small wind turbines don’t use the same technologies found on the megawatt-scale behemoths populating wind farms. Discover some of the important differences.

A critical look at wind power
Here's one person's opinion on why wind power isn't all it's cracked up to be. Read it, then add your own opinions to the discussion.

A car designed for blind people
Engineering students at Virgina Tech designed a car that can be driven by people with impaired vision, including those who are compelety blind. Find out how they did it.

New Products

Self-aligning spherical bearings
The igubal spherical bearings are self-aligning components — rod ends, clevis joints, flange bearings, pivot bearings, and pillow blocks — made of high-performance plastics. The self-lubricating bearings damp vibrations and operate in liquids, chemicals, dirt, or dust. The devices adapt to angular deviations and can replace special housings. The bearing's housing is made from igumid D, a highly shock-resistant plastic, and its spherical balls are made from iglide L280 material.

Self-lubricating linear-bearing pillow blocks
The "Lube for Life" self-lubricating linear-bearing pillow blocks eliminate lubrication systems and provide continuous bearing lubrication and protection. Available for open or closed pillow block assemblies, Lube for Life is now an option for the company's Super Ball Bushing Bearings and Super Smart Ball Bushing Bearings.
Lube for Life pillow blocks work through self-lubricating cartridges pressed into each end of the pillow-block housing, with the linear bearing itself initially lubricated with EP2 grease. The Lube for Life polymer is under constant pressure against the 60 Case shafting ensuring a film of lubricant is always present between the ball bearings and the inner race.

Selection and Application of Lubricants for Linear Motion
Sponsored by Thomson
DATE: December 20th, 2009
TIME: 2:00pm ET/11am PT

More questions come into the Thomson technical support team regarding proper lubrication of mechanical motion control components than for almost any other topic. Unnecessary machine downtime and high maintenance costs are easily avoided with the right information in hand. As the inventor of the Linear Ball Bushing Bearing® and with over 60 years mechanical motion application experience, Thomson is uniquely qualified to help answer these questions.

What IS the number one lubrication mistake? What is the difference between weight and viscosity? Which lubricants best extend product life? Which are best for food grade or submerged applications? What is the best way to remove grease? This webinar will answer those questions and more. Proper lubricant selection can significantly improve performance and extend product life. This webinar will cover lubrication for Plain Bearings, Ball Screws, Ball Splines, Linear Bearings and Profile Rail.
