Surface Finish: Ra ≤ 0.8 µm to minimize shaft wear.
Challenge: Saltwater corrosion in propeller shafts.
VIIPLUS Solution: C95400 aluminum bronze bushings with 150 MPa load capacity.
Result: 10-year lifespan in tidal turbines without maintenance.
Challenge: Abrasive dust in crusher joints.
VIIPLUS Fix: C86300 manganese bronze flanged bearings with graphite plugs.
Result: 300% longer service life vs. traditional bushings.
Challenge: Weight reduction in landing gear.
VIIPLUS Innovation: C63000 nickel-aluminum thrust washers (30% lighter than steel).
Challenge: Grease contamination in dryer rollers.
VIIPLUS Design: Self-lubricating C93200 bushings with helical oil grooves.
Outcome: Zero lubrication needed for 15,000+ operating hours.
| Parameter | Standard Bearing | VIIPLUS Custom Bearing |
|---|---|---|
| Lead Time | 1–2 days (in-stock) | 2–3 weeks (tailored design) |
| Load Capacity | Up to 100 MPa | Up to 200 MPa (reinforced alloys) |
| Temp Resistance | 200°C | 400°C (C95400 variants) |
