, Are you experiencing problems with your Slip Rings or Rotary Unions?... Cleaning too much? Waiting on units to arrive? Paying too much for parts? Not adaptable enough? ...

Resulting in... DOWNTIME

Slip ring and rotary joint assemblies are used in a large variety of applications. They provide power, hydraulic and signal transmission through rotating parts. In construction and maintenance machinery they enable greater than 360-degree rotation connectivity to arms and tooling. BGB has found that our focus on reliability and safety has made us a strong engineering partner to construction during times of supply chain and cost pressures. Looking towards the next generation of compact electric excavators, BGB is uniquely positioned to provide engineering support to companies with green ambition without compromising on quality and cost. This shift towards electrification sees a greater emphasis on signal and power requirements as fossil fuel driven machinery is phased out. For operators, safety remains key as indoor working, relay of battery status and positioning information brings greater complexity and possible failure modes. With experience in renewables and battery charging dating back to the mid-90s, BGB is a safe pair of hands for this latest industry challenge.



Designers Top Tips:

• Space envelope and your future requirements. What upgrades might the operator want to make, is it worth building in some extra channels? • Foot-printing: If you are considering a tool with a high power requirement, think about your brush material as it may pay to use a grade with good conductive and thermal qualities. • Consider adding a FORJ for high-speed data transfer as this may save space whilst improving data resolution.

Proven reliability ahead of production
