Effortless, Intelligent, and Automated Lubrication Management

The LUBExpert ON-GUARD keeps it simple. Connect and manage your device from anywhere, utilizing its integrated web server that is compatible across all devices, including tablets and smartphones, without the need for installing any software, relying on cloud services, or purchasing additional licenses.

At the heart of its functionality is the automatic operation feature. The SDT LUBExpert ON-GUARD takes over the complex job of timely bearing lubrication, significantly reducing manual labor and minimizing grease consumption. This leads to enhanced machine performance and asset dependability, thanks to the advanced SDT LUBrain precision lubrication algorithm. It fine-tunes the lubrication process, ensuring grease is applied only when necessary and in accurate amounts.

Simplifying maintenance even further, the LUBExpert ON-GUARD utilizes smart algorithmic insights to negate the extensive need for training. Its ultrasound technology combined with CONMONSense sensors, administers the perfect grease volume in response to the bearings’ condition. The sensors are designed for instant use, eliminating any setup steps for a truly plug-and-play experience.
