SLSM 1002 - Sintered Bronze Plain Bearing
Bronze-Sintered Metal - maintenance-free
Material - Characteristics
Self-lubricating, maintenance-free, with fine distributed solid lubricant.
Within the sintered powder metal matrix the solid lubricant (99,9 percent highly clean, chemical neutral electrolyte graphite) is enclosed pre-loaded in micro distribution.
Therefore in order to ensure a maintenance-free, self-lubricating performance there is always sufficient lubrication all over the bearing area, including for small angular movement, vibration, etc.
The highly clean lubricant has the advantage that oxygen corrosion in water or humid atmosphere at the bearing shaft and the surrounding parts will not occur.
