Detail product description
Economical bearing requiring less number of lubrication


a economical bearing solution, requiring minimum number of oil-supplying
#300 is a special type of oilless bearing material, in which the porous structure resulted from the cast iron growth phenomenon is effectively utilized to contain lubricant oil therein.
l The number of oil-supplying can be reduced drastically compared to a gunmetal bearings
l Oil film is well maintained due to lubricating oil is retained in porous structure.
l No limitation for motion style and sliding surface.
l Larger-sized products are available compared with conventional oil-retaining metal powder-sintered bearing.
l Further machining allowance is available.


Features l The number of lubrication can be reduced drastically compared to a gun metal bearing
l Lubricant oil being contained in porosities, an oil film can be stably maintained improving resistance to wear
l No limitation for motion style and sliding surface
l Capable to manufacture larger sized products compared with oil-impregnated sintered bearing
l Available in standard products with various sizes and material for machining
