Broich Systemtechnik specializes in tailor-made solutions for transporting industrial unit loads. The range includes belt conveyors, roller conveyors, workpiece carrier systems, multi-track conveyors, hinged conveyors and storage systems. The GF3 and GF8 series are available in the belt conveyor range: The GF3 models are suitable as "all-rounders" for small to medium-sized products. With the modular GF8 series, a variety of designs can be realized; thanks to the flexibility and individual design options, the belts can be adapted to the conveying task and the respective installation conditions. A wide range of belts made of plastic, steel and stainless steel is available.

Friction must remain low
The long service life of these conveyor belts is primarily due to the roller bearings that are used to support the drive and deflection rollers, among other things. Broich Systemtechnik has been relying on products from Findling Wälzlager for years. While the bearings in the GF8 conveyor belts are exposed to high loads and must have a high sealing effect, smooth running is particularly important for the bearings in the GF3 series. Many roller bearings are installed together for the center tension roller and the deflection rollers. Excessive friction in the seals would increase the power consumption of the drive and even make larger drives necessary. Broich Systemtechnik therefore relies on the Xspeed series from the Karlsruhe-based rolling bearing experts in this area, which is suitable for smooth-running and therefore energy-saving applications thanks to its special sealing technology. "The Xspeed bearings are actually designed for high-speed applications," explains Klaus Findling, Managing Director of Findling Wälzlager. "In terms of speed, the bearings are naturally completely underpowered in this application. Because the Xspeed special solutions are part of our standard range, we were still able to make Broich Systemtechnik an attractive overall offer and guarantee rapid availability. These bearings therefore represent an optimum solution for this customer, both technically and economically."

All elements available at short notice
In addition to the Xspeed bearings, other proven Findling solutions are used in Broich Systemtechnik's conveyor belts: For housing bearings, for example, the company has relied on the Abeg Supra series with corrosion-protected inner and outer rings, which has been successful for more than 20 years and uses a ball pressure screw instead of a self-tapping screw for fastening on the shaft. These solutions became part of the Xclean series in 2012 and are therefore also part of Findling Wälzlager's eXtreme range.

Broich Systemtechnik also requires self-aligning ball bearings for the conveyors in the series, which have to compensate for shaft deflection due to the high loads on the drive drums - Findling also found the right product in this area. Last but not least, customers from the food industry require a variety of different stainless steel solutions - deep groove ball bearings as well as self-aligning ball bearings or housing bearings. These products are also available to customers at short notice.

"Broich Systemtechnik often requires individual storage technology for customized systems," says Klaus Findling. "This is where we can score points with our full range and the variety of performance classes. For example, we supply cam followers and support rollers as well as self-aligning ball bearings from renowned manufacturers in Japan and Europe." pb

ABEG-eXtreme series
The special range is divided into the four series Xforce, Xspeed, Xtemp and Xclean. These cover different requirements in terms of operating conditions: Xforce bearings are solutions for high loads at low rotational speeds, where unfavorable tribological conditions prevail and the lubricating film cannot be reliably built up with standard solutions; the Xspeed series, on the other hand, was developed with a focus on high speeds and energy efficiency. The Xtemp series stands for temperature stability in excessively hot or cold conditions, while the Xclean series offers robust bearing technology for corrosive environmental conditions, as well as special designs for clean room applications.
