Flexible coupling
The EKH flexible coupling is designed to handle 10,000,000 cycles at
rated torque. A resilient polyurethane insert damps vibration and
absorbs slight shaft misalignment in the lateral, axial, and angular
directions while transmitting torque free of backlash.
The EKH is available with English, metric, keyed, and smooth bores and
handles torque from 15 to more than 19,000 lb-in. Three different
insert-hardness levels are available for a choice between torsion
resistance and flexibility levels.

Plastic bearings save money and last
longer
 Low-cost iglide
plastic bearings require no oil. They are a self-lubricating and
maintenance-free alternative to bronze or ball bearings. Lower costs
and extend service life with predictable wear rates and life
expectancies. With more than 20 material blends to choose from, igus
offers a longer-life solution at a lower cost. If an iglide bearing is
not available to meet your specifications, igus will custom design a
bearing to suit your needs. Plastic bearings are UV-resistant, provide
excellent vibration dampening and will not corrode. Ask for
complimentary samples and design advice today.

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.

The need to respond and capitalize on new customer requirements is more
important than ever during the current economic downturn. However, the
pressures of globally distributed design teams and more stringent time,
cost, regulatory and quality requirements continue to complicate the
product development process. In order to succeed, Small and Medium
Organizations need to collaborate across project teams more efficiently
to bring the right products to the marketplace at the right time.
In this live webcast, you’ll learn best practices to effective
collaboration:
- Enabling concurrent engineering with members of a distributed
design team
- Conducting efficient design reviews across the value chain
network
- Creating a controlled collaboration environment
- Proving secure collaboration to the design team and
suppliers
