High-precision machined sheets, rods, and wear-resistant custom components engineered by Tianjin Beyond Technology.
Oil-filled Cast Polyamide 6 (commonly referred to as Oil PA6 or Self-Lubricating MC Nylon) represents a milestone in engineering plastics. By introducing a liquid lubricant package uniformly during the anionic polymerization process of caprolactam, the material gains a built-in, non-leaching lubricating film.
Unlike standard polyamide materials that require external greases or dry lubricants which wear off quickly, Oil PA6 features a micro-distribution of lubricating oil throughout its structural polymer matrix. As the material slides against matching metallic surfaces, micro-lubrication occurs continuously, decreasing wear by up to 5 times compared to cast nylon and POM.
This molecular integration preserves structural tensile and flexural strength, keeping thermal dimensional stability high and absorption rates lower than raw Nylon 6. It eliminates the traditional slip-stick effect in reciprocating heavy machinery components.
Our advanced manufacturing facility coordinates high-volume anionic casting and CNC machining.
Comparing the tribological and structural values of Oil PA6 against conventional engineering metals and competing polymers.
| Performance Metrics | Oil PA6 (Cast Oil-Filled) | Standard PA6 (Unfilled) | POM-C (Acetal Co-polymer) | Phosphor Bronze |
|---|---|---|---|---|
| Coefficient of Sliding Friction (Dry) | 0.10 - 0.15 | 0.35 - 0.42 | 0.25 - 0.32 | 0.30 - 0.40 |
| Limiting PV Value (MPa · m/s) | 0.85 - 1.20 | 0.25 - 0.35 | 0.45 - 0.60 | 1.50 - 2.50 (with lube) |
| Density (g/cm³) | 1.14 | 1.15 | 1.41 | 8.80 |
| Tensile Yield Strength (MPa) | 70 - 80 | 80 - 85 | 65 - 70 | 250 - 400 |
| Water Absorption Saturation (%) | 1.8 - 2.2% | 5.5 - 6.5% | 0.8% | 0.0% |
| Dynamic Wear Rate (µm / km) | 1.2 - 2.5 | 8.0 - 15.0 | 4.5 - 8.0 | Highly dependent on lube |
Continuous release of the incorporated fluid prevents stick-slip in low-velocity applications, ensuring precise control in telescoping crane booms and heavy wear guides.
The continuous layer of surface lubricant cuts friction and thermal buildup, offering a five-fold wear resistance increase over standard cast nylon counterparts.
With a density of 1.14 g/cm³, Oil PA6 cuts down components weight by roughly 87% compared to traditional bronze, saving energy and cutting down assembly times.

How leading industrial sectors deploy oil-filled cast nylon to address wear, load, and dynamic friction challenges.
In saltwater environments, lubrication with conventional greases is problematic. Oil PA6 stern bearings, sheaves, and rudder bushes run cleanly underwater, preventing corrosion and reducing slip-stick wear.
High-load, slow-moving telescoping booms and wire rope sheaves experience severe high load friction. Substituting bronze with self-lubricating oil-filled MC nylon prolongs wire rope life and avoids grease drop.
In steel hot-rolling mills, slider blocks and coupling wear pads operate under severe mechanical pressure and hot water sprays. Oil PA6 withstands shock loading and isolates surface vibration.
