Stop Guessing, Start Greasing: Precision Motor Lubrication with Ultrasound
Technology
Maximize Bearing Life, Eliminate Downtime, and Achieve True Predictive Maintenance (PDM) for Electric Motors and Generators.
Ultrasound-Based Greasing Services
Traditional lubrication methods are failing industrial facilities. Relying on outdated time-based scheduling or guesswork—whether you grease weekly, monthly, or quarterly—ultimately leads to one of the two most common and costly causes of bearing failure: over-greasing or under- greasing. Both scenarios dramatically reduce bearing lifespan, spike maintenance costs, and increase the risk of catastrophic, unplanned downtime. Renown Electric is harnessing ultrasound technology to enhance the reliability and efficiency of this critical maintenance task.
We Leverage condition-based ultrasound technology to listen to the real-time condition of your electric motor and generator bearings. This method moves lubrication away from rigid schedules and into the realm of true Predictive Maintenance (PDM), ensuring your bearings are serviced at the right
time with the exact amount of grease needed, eliminating costly errors and maximizing asset longevity.
The Ultrasound Advantage: How It Works
The core of our precision service lies in acoustic monitoring. Ultrasound equipment acts as a highly sensitive stethoscope, allowing our certified technicians to “hear” the high-frequency sounds of friction within a running bearing. Every bearing establishes a healthy baseline decibel (dB) level. As grease degrades or is depleted, friction increases, causing the dB level to rise significantly. We don’t guess the amount of grease—we meter it while monitoring the dB level in real-time. The lubrication process is immediately stopped the moment the reading drops back to its established healthy baseline, ensuring the bearing is perfectly charged without the detrimental effects of over-pressurization.
Benefits & Return on Investment
Moving to an ultrasound program is the single most effective way to achieve true Predictive Maintenance. By eliminating the guesswork of traditional greasing, we
directly extend your bearing service life and drastically reduce the number of costly, premature failures. This proactive approach means your maintenance team can move away from reactive fixes and time-based guesses, allowing you to schedule bearing maintenance precisely when needed, keeping your critical motors and generators running reliably for longer.
The financial return on investment (ROI) is immediate and substantial. Because Renown Electric technicians add only the precise amount of grease
required, you realize a significant reduction in lubricant waste. Furthermore, properly lubricated bearings run cooler with less friction, translating directly into lower energy consumption across your entire motor fleet. Over time, these optimized maintenance practices drastically decrease your spending on labor, replacement parts, and emergency repairs.
1: Pre-Service Assessment
During this initial phase we review your motor inventory, bearing and grease types, maintenance history, and current lubrication routes to fully understand your specific needs.
2: On-Site Ultrasonic Greasing
The initial visit is used to establish a baseline for all motors across the facility. Once this baseline is set, the re-lubrication process is carried out while monitoring real-time dB readings and applying grease only as needed based on deviations from the baseline.
3: Post-Service Documentation
This will include before-and-after dB reports, the exact amount of grease applied to each asset, and condition-based recommendations for the next service interval.
Supported Equipment & Applications
The versatility of ultrasound allows our service to cover virtually any industrial rotating asset. This includes Electric Motors (AC and DC, all voltages and HP ranges), Generators, and critical auxiliary equipment such as Pumps, Fans, and Gearboxes. If it spins, we can precisely lubricate it.

Types of Bearing Damage and Failures
Bearings are an essential component of electric motors. They provide shaft support, facilitate even load handling, reduce friction between the shaft and stationary parts of the motor, and increase the longevity and reliability of rotating assets.
