Canton, OH — Dec. 26, 2002 — Timken has introduced an intelligent wireless technology bearing for the rail industry. The new Guardian bearing is an enhancement to the original AP, AP-2 and SP family of bearings developed by Timken over the past 50 years.
“For 80 years, Timken has played a vital role in the advancement of the railroad bearing industry,” said Thomas S. Dupaski – president – rail. “The Guardian bearing contains new wireless technology that provides rail operators with information to increase bearing, wheel and track efficiency. We have introduced the next generation of technology that will revolutionize the rail
Located inside the existing AP, AP-2 and SP bearing designs, the Guardian bearing self-powered sensing system sends radio frequency transmissions of data to a receiver located on the train. The data can be stored locally or networked with onboard or off-site computers for immediate action or stored for further analysis.
The sensors inside the Guardian bearing are capable of transmitting data regarding speed, temperature and vibration — three critical factors to the success of railroad bearings, wheels and tracks.
This bearing is currently undergoing testing. “We anticipate that our customers will be greatly impressed with the amount of data that can be received from the Guardian bearing,” said Sam Williams, chief engineer – rail. “The technology integrated into our bearings has the potential to detect, earlier than by current methods, damage to bearings, wheels and tracks that can lead to derailment.”
“We are continuing development of this technology to provide even more information and to fit other applications,” said Dupaski.
