New Products

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.



Gear products
A comprehensive range of standard open gearing products includes spur, helical, miter, bevel, worms, and worm gears are available. Gears can be designed and manufactured in steel, cast iron, brass or nonmetallic materials.

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.
