SKF / INA PermaGlide PAP (P11)
SKF / INA PermaGlide PAP (P11) is part of the SKF / INA PermaGlide range of metal-polymer composite plain bearings (steel-backed, sintered-bronze interlayer, ptfe or pom sliding layer). Because it runs with added lubricant, PAP P11 aligns most closely with Bushingo BP25 oil-impregnated sintered bronze — both target lubricated, higher-load bushing duty. Where the buyer prefers a fully maintenance-free dry solution, direct them to the P10 analogues (Metagliss composite or BP25 self-lubricating). SO16 sintered alloy is an alternative substrate option.
Specification
| Brand | SKF / INA PermaGlide |
|---|---|
| Series | SKF / INA PermaGlide PAP (P11) |
| Material | Steel backing, sintered bronze interlayer and a POM (acetal) sliding layer with lubrication indentations/pockets; requires initial and periodic oil or grease lubrication. Metal-polymer composite for lubricated, higher-load service. |
| Forms | Wrapped cylindrical bush |
| Typical size range | Comparable bore range to the P10 bushes — roughly 3 mm to ~100 mm bore, thin-walled — general guidance only. |
Key features
- Lubrication pockets in the POM layer retain grease/oil, reducing re-lubrication frequency
- Higher load capacity and longer life than the dry P10 material where lubrication is available
- Suited to higher surface speeds when lubricated
- Robust against edge loading and moderate misalignment
- Same compact steel-backed construction for press-fit housings
Typical applications
- Higher-load hydraulic components and cylinders
- Heavy machinery pivots and linkages with grease service
- Agricultural and construction equipment with lubrication points
- General engineering bushings where periodic lubrication is acceptable
