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.

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.
