Back to Rulon®
Rulon® 641 is manufactured from FDAcompliantmaterials which possess excellent load and wear characteristics. It offers excellent, continuous non-lubricated service up to 10,000PV â higher for intermittent service. While the load capacity of Rulon 641is generally limited to 1,000psiatroom temperature, deformation is a function of wall thickness, temperature, and load. Its compatibility with a wide array of mating surfaces, including mild steel,303and 316stainless steel, as well as harder materials, make it a good choice for most food and pharmaceutical bearing applications.
Notable Material Features
- High compression strength
- Low coefficient of friction
- Excellent abrasion and corrosion resistance while running without lubrication
