Pillow blocks
The BBXBLK-HCP and BBXBLK-UCP pillow blocks feature both locking
collar and set-screw types. The solid-base dual-seal-type pillow blocks
have cast-iron housings and are designed to fit shafts ranging from
½ to 3½-in. in diameter. The units incorporate one
lubrication fitting.

Motion Resource Center
 Every solution
requires the right tools to get the job done correctly. Danaher Motion
has created a web page with descriptions and access to motor
sizing/selection software, on-line servo technology database, an
engineering toolbar for various calculations and more. The site even
has more details concerning a Motion Control Handbook that will be a
great resource even when a computer with web access is
available.

Timing belts
More than 55 different sizes of Synchrochain timing belts are now
available. Synchrochain belts are designed for applications that place
extreme demands on belt performance, such as maximum power transmission.
The belts resist fuels, oil, grease, and cleaning agents, as well as
moisture and temperatures ranging from –40 to 100°C.
The belts' smooth back side allows the use of back pulleys. Aramid
fiber-tension members have a bifilar "S" or "Z" twist, which lets the
belts withstand extreme cases of starting torque, as well as shock loads
and high dynamic strain. The teeth have also been reinforced on the
pulley side.

Energy Efficiency Web Conference & Expo –
May 14
Do you know you can get in-depth education on energy-efficiency and all
the benefits of an in-person trade show without ever leaving your desk
or spending a dime?
The intelligent use of energy is making headlines. Product designers and
manufacturers are striving to deliver products that consume less power,
extend battery life, generate less heat, or work from alternative energy
sources. Our Energy Efficiency Web Conference and Expo will
educate design engineers, product developers, and managers on how to
make the best use of energy-efficient product innovations and devices,
and on how to arrange them in systems to lower power consumption and
stay "green." This special one-day event will include sessions
on such areas as:
- Power-efficient drive techniques for lighting
- ROI for high-efficiency capital equipment
- Energy monitoring and energy standards
- Designing for SEMI S23 and the Energy Act of 2007
- Working with alternative power and battery technology
Make plans now to attend the Energy Efficiency Web Conference and Expo. The
event offers a full day of live webinars and interactive booths, along
with a Resource Center where visitors can download or link to additional
materials.

Efficiency in Fractional HP Motors & Gearmotors
Sponsored by Groschopp
DATE: April 16th, 2009
TIME: 2:00pm ET/11am PT
Efficiency is often one of the last factors that design engineers think
about when specifying for an OEM application, yet it is critical to a
successful, optimized design in many ways. Join Groschopp engineers Ron
Didier and Jared Birk for an overview of efficiency as it relates to
other design considerations such as power source, operating cost,
temperature, purchase cost and size.
Webcast attendees will receive an early release download of the new STPe
desktop design tool that allows engineers to calculate operating cost
based on speed, torque and power requirements and local kwh energy
costs.
