CASE STUDY:
Precision Cleaning of Ball Bearings:
Replace nPB Solvent with AeroTron-AV-5408

Precision ceramic & steel ball manufacturer needed to determine whether AeroTron® AV-5408, a Boeing-approved solvent, can deliver equal or superior cleaning performance as compared to nPB on ceramic and chrome balls.

The Objective & Challenge:

Reliance Specialty Products conducted a controlled test cleaning on ceramic and chrome balls to evaluate the effectiveness of AeroTron-AV-5408 as a replacement for nPB in precision ball bearing aerospace cleaning applications.

Key challenges included:

  • Complete cleaning of all balls en masse in basket

  • Remove visible oil contaminant on parts

  • Remove machining oils trapped in space between balls

  • Ensure balls completely dry after cleaning cycle

Results

AeroTron-AV-5408 achieved consistent and high-quality cleaning results across both ceramic and chrome ball bearing substrates

  • Key outcomes:

    • Effective removal of machining oil contaminants

    • Uniform surface cleanliness across all ball bearing balls

    • No visible residue on entire basket of ball bearing balls.

The results met the customer’s cleanliness requirements and switched from nPB to AeroTron-AV-5408.

Equipment & Chemistry

  • Solvent: AeroTron-AV-5408 (Boeing-approved)

  • System: Reliance ULTRA 2012LE Ultrasonic Immersion Vapor Degreaser

Cleaning Process

The cleaning process was designed to simulate production-level conditions:

  • 1 minute immersion dwell

  • 3 minute ultrasonic immersion

    1000 watts of ultrasonic power

  • *Six oscillations with 10-second immersion in and out of solvent (2 minutes)

  • 90-second refrigeration zone (freeboard flash-off)

  • TOTAL PROCESSING TIME: 7.5 minutes

(*Oscillations allow the basket to be fully submerged in the ultrasonic liquid solution for a select period of time and then raised just above the liquid level for a select period of time. This allows the solvent to flush/fill IDs/blind spots and tight geometries of part(s). The ULTRA BHE automated lift allows you to program the cleaning recipe to your desired need including oscillations if preferred)

Process Highlights

  • Ultrasonics enabled penetration into crevices between balls

  • Controlled oscillation ensured uniform exposure and repeatability

  • Refrigeration Zone drying delivered residue-free finishing

VAPOR DEGREASING
EQUIPMENT USED FOR THE CLEANING:

Reliance ULTRA 2012LE Vapor, Immersion, Ultrasonic Immersion & Distillate Spray Vapor Degreasing System.

SOLVENT USED:

AeroTron-AV-5408 is Boeing Approved Vapor Degreasing Solvent.

AeroTron-AV-5408 is specially formulated for metal, plastic and elastomer compatibility in aerospace cleaning and can be used to clean titanium with improved health, safety, regulatory, permitting and environmental benefits.

RECOMMONDATION:

Replace nPB solvent with AeroTron-AV-5408 in the vapor degreaser & consider purchasing an ULTRA 2012LE vapor degreasing system with 1000 watts of ultrasonic power for optimized ball bearing cleaning.
