Overhung load adaptors (OHLA) provide both overhung radial and axial load support to protect electrified mobile equipment motors from heavy application loads, extending the lifetime of the motor and alleviating the cost of downtime both from maintenance costs and loss of production. They seal out dirt, grime, and other contaminants too. Zero-Max OHLAs are available in an extensive offering of standard models (including Extra-Duty options) for typical applications or customized designs.

Bosch and the Dutch map and traffic information provider TomTom have achieved a breakthrough in the development of high-resolution maps for automated driving.
The team has become the first worldwide to create a localization layer using radar signals, which will be indispensable for maps like these.
So far, video data has been used for this purpose. Bosch's "radar road signature" is made up of billions of individual reflection points. These are formed everywhere that radar signals hit -- for example, on crash barriers or road signs -- and reproduce the course a road takes. Automated vehicles can use the map to determine their exact location in a lane down to a few centimeters.
"The radar road signature is a milestone on the path toward automated driving. It will enable automated vehicles to reliably determine their location at all times," says Bosch board of management member Dr. Dirk Hoheisel.
The huge advantage of Bosch's radar road signature is its robustness: unlike maps that rely exclusively on video data for vehicle localization, the radar road signature also works reliably at night and in conditions of poor visibility. Moreover, the Bosch radar road signature only transmits 5 KB of data to a cloud per kilometer -- this data volume is twice as high using a video map. It is expected that by 2020 at the latest, the first vehicles will provide data for the radar road signature in Europe and the United States.
The two companies have been working intensively on the radar road signature and its integration into TomTom's high-resolution overall map since the beginning of their collaboration in July 2015. Bosch is a global market leader in the field of radar sensors, with 77-GHz technology and detection ranges up to 250 m.
By comparison, video sensors only have a maximum detection range of 150 m.

The main challenge was finding a way to adapt existing radar sensors for this task. When used in a driver assistance system such as automatic emergency braking systems or adaptive cruise control (ACC), the sensors detect moving objects. But in order to generate the radar road signature, they also need to be able to detect static objects, which meant that existing radar sensors had to be modified. The next generation of Bosch radar sensors will be able to provide the data required for the radar road signature.
"Cars arriving on the market in years to come with the assistance functions of tomorrow will be running the map for the automated vehicles of the future," Hoheisel says.
One million vehicles will keep the high-resolution map up to date
High-resolution maps are essential for automated driving, providing information that goes beyond the area that sensors are able to monitor. Unlike maps for today's navigation devices, they are made up of a number of overlapping layers:
Each of these layers of a high-resolution map for automated driving need to be regularly updated -- the dynamic layer even in real time.
"We currently expect that we will need fleets for freeways in Europe, North America, and Asia Pacific that each consist of around one million vehicles in order to keep our high-resolution map up to date," says Hoheisel.
Current data for each of the layers will be generated by the vehicles' on-board sensors while they are driving. Communication boxes such as Bosch's Connectivity Control Unit will transmit the radar sensors' data from the vehicles to the manufacturers' cloud and then on to the Bosch IoT Cloud. Bosch will use this to create the radar road signature, which is compatible with all conventional map formats. TomTom's responsibilities will include integrating the radar road signature in the overall map and distributing it.
