SF-80 Self-lubricating Bearings

Self-lubricating Bearings Rolling SF-80 boundary lubricated bearings to high-quality low-carbon steel substrate, sintered porous spherical bronze powder, surface modified POM (POM) is firmly fitted. Surface rolling storage pit in order to achieve a good lubrication between the friction. It has good wear resistance and load carrying capacity, anti-corrosion steel back surface coating.

Resistance

SF-80 surface of the polymer chemical resistance, corrosion resistance and therefore it depends on the appearance of the plating layer and steel back. The back surface of copper or tin-plated steel, can effectively prevent atmospheric corrosion; if operating in corrosive media, etc. galvanized steel back can.

SF-80 and wear characteristics under oil lubrication conditions, as follows: it's "running-in" wear rate is very small; seen from the figure line, the applied grease when assembled consumption to a certain extent, the wear rate gradually increases, as shown in dashed lines; if refuel again before the wear rate rises, the wear rate remained stable; when the time is appropriate refueling interval, the material life can be greatly extended. The time interval depends on the fuel accumulated wear.
Grease lubrication: ambient temperature is below 80 ℃, recommended the use of lithium soap grease; ambient temperature above 80 ℃, recommended the use of silicone-based grease; not recommended grease containing EP additives.
