Aluminum bronze bearings with embedded solid lubricant Free I Features• Usable in seawater.• Has superior heat resistance.• Not brittle at low temperatures and may be used at very low temperatures. Test data Journal oscillation test in sea water <Testing conditions> Oscillating cycle : 60cpm Oscillating angle :±10° Test cycle(time) : 100,000cycle(27.8hrs.) Ambience : in artificial sea water temperature 20±5° *SL4 is used for this test data. W Service range The values in parentheses are static bearing pressures, which are the bearing pressures in applications with no motion or very small motion (^0.0017m/s[0.1m/min]). ^Above values are applicable when solid lubricants SL1 are used. When you use standard #500AB series in the temperature and over, contact us for more information. ^The values shown above are typical values, not the standard values. (Note) Compressive strength is 0.2% Please indicate the type of motion (rotation, reciprocating, rotation & reciprocating) for custom-made products. Solid lubricant, SL401 and SL403 are not lead-free.
