The Ultraprobe 201: Grease Caddy (UP201) Ultrasonic Lubrication Instrument, engineered and manufactured by UE Systems Inc. (USA), is a dedicated condition-based maintenance tool designed to solve one of the most persistent and costly failure modes in industrial plants: improper bearing lubrication.

Reliability engineering studies demonstrate that over 60% of premature bearing failures stem from inadequate or improper lubrication, with over-lubrication occurring far more frequently than under-lubrication. When technicians grease bearings based on arbitrary calendar schedules or guesswork, excessive grease volume ruptures protective bearing seals, creates hydraulic fluid friction, generates excessive thermal runaway, accelerates lubricant degradation, and risks catastrophic electric motor winding burnouts. The Ultraprobe 201 Grease Caddy transforms routine grease application into a precise, condition-based protocol driven by real-time acoustic friction feedback.

Key Engineering Features & Operational Advantages:
- Direct Mounting to Industrial Grease Guns: Includes a universal heavy-duty mounting bracket designed to clamp securely onto virtually any standard manual lever grease gun, pistol-grip gun, or cordless battery-powered grease gun. This creates a compact, all-in-one handheld maintenance tool, allowing technicians to lubricate and listen simultaneously without handling multiple instruments.
- Magnetic Contact Sensor for Bearing Housings: Comes standard with a specialized magnetic mount contact sensor paired with an expandable coiled cable. The magnetic sensor attaches firmly to the bearing housing adjacent to the zerk fitting, continuously transmitting structure-borne ultrasonic friction vibrations directly to the instrument.
- Real-Time Audio & LED Visual Feedback: As fresh grease enters the bearing cavity, the high-frequency friction hiss heard through the deluxe noise-attenuating headphones subsides, and the LED bargraph indicator drops accordingly. The moment the decibel level bottoms out and levels off, the technician knows the optimal lubricant film thickness has been re-established and stops pumping immediately.
- Integrated Zerk Fitting Spotlight: Features a built-in, forward-facing high-intensity LED lamp that illuminates dark mechanical cavities, conveyor frames, and recessed grease fittings, eliminating the awkward need to hold an auxiliary flashlight in dark plant environments.
- Incipient Fault Identification: If grease is applied and ultrasonic decibel levels fail to decrease, or if rhythmic clicking and scratching sounds persist, the technician receives instant acoustic confirmation that the bearing has suffered subsurface mechanical damage (spalling or race micro-cracks) and requires scheduled mechanical replacement.

Typical Industrial Applications:
- Lubrication management of AC/DC electric motors, industrial exhaust fans, centrifugal pumps, and compressors.
- Condition-based regreasing of conveyor pillow blocks, idler rollers, and ball mills in mining, cement, and pulp & paper facilities.
- Automated packaging lines, high-speed rotary bottling equipment, and textile manufacturing machinery.
- Preventing blown bearing shields and avoiding costly grease contamination inside motor stator windings.
