Lubrication & Anti‑Rust Solution for Underwater Robot Bearings, Simulated 300‑m Water Pressure 20‑h Verified
ROV and AUV underwater robots are widely used for subsea pipeline inspection, offshore wind‑power maintenance, deep‑sea scientific sampling and special underwater operations. Equipment operates under extreme conditions: hundreds‑meter deep‑sea high pressure, salt‑water erosion and sharp temperature fluctuation.
Thrusters, underwater motors and sealed bearings are key components. Their performance directly determines equipment reliability and maintenance cost.
Many marine equipment manufacturers only focus on basic water‑proof performance, ignoring critical deep‑sea challenges:
‑ Grease squeezes out and loses protection under deep‑water high pressure
‑ Grease emulsifies and dilutes after long‑term seawater immersion
‑ Salt‑water penetration causes bearing rust and equipment breakdown
‑ High starting resistance under low sea‑water temperature raises motor power consumption
‑ Grease softens and leaks under continuous operating heat
‑ Incompatibility with seals & plastics leads to water leakage
These risks result in costly factory repair or even subsea mission failure.
Baoxing Lubricant’s BX‑455/C(111)‑WY high‑adhesion waterproof silicone grease solves bearing lubrication, water‑proofing, anti‑rust and sealing reinforcement for underwater equipment.
Key Advantages
High adhesion, anti‑wash‑off under deep‑sea pressurePremium silicone base oil plus special adhesive additives build dense durable oil film. Resist water flow scouring and long‑time seawater immersion, block moisture and avoid bearing corrosion.
Long‑term anti‑rust & anti‑wear, prevent seizure & noiseComplete oil‑film coverage isolates chloride salt erosion. Keep bearings running quiet and smooth underwater. Extend service life of thrusters and bearings, cut replacement & maintenance cost.
Stable from ‑20℃ to 70℃Smooth startup in cold deep sea without extra motor load. No softening or dripping during continuous high‑temperature operation. Keep stable lubrication and sealing performance across temperature changes.
Rubber & plastic compatible for better sealingCompatible with O‑rings, gaskets and engineering plastics. Lubricate and fill tiny sealing gaps to improve overall waterproof performance.
Note: Material compatibility test is recommended prior to mass application for different sealing materials.
Typical Applications
✅ ROV / AUV underwater robot thruster bearings
✅ Underwater DC & servo motor bearings
✅ All types of sealed deep‑sea bearings
✅ Underwater water pump & transmission bearings
✅ O‑ring and gasket sealing lubrication points
✅ Offshore wind inspection & deep‑sea sampling equipment
Target Customers

Deep‑water Test Verification
BX‑455/C(111)‑WY has passed simulated 300‑meter water‑pressure 20‑hour continuous running test. Grease retention meets specification for phased operation under 300‑meter depth.
For depth above 350 m, custom validation services are available:
▫ 72‑hour static seawater immersion test under 350‑m equivalent pressure
▫ Low‑temperature startup load test
▫ Long‑duration full‑load running test
▫ Post‑test bearing anti‑rust inspection
▫ Long‑term rubber‑plastic compatibility assessment
Material compatibility and condition simulation tests are strongly suggested before mass production to reduce field risk.
