HALF FINISHED PRODUCT CUSTOMIZED PRODUCT

Plastic bearing exclusively used for water lubricating application
Material INDEX OILES 250-07 (425-07) Bushing material 25S OILES 250-07 (425-07) Bar stock 25M OILES 250-07 (425-07) Plate material 25P
OILES 425 is another phenol resin bearing, using the same special cotton as of OILES 250 as base material, but given a specific treatment to make it a bearing exclusively used for water lubricating application. Features Superior to metallic bearings in its effectiveness for foreign matter embedding, shock resistance and muffling Excellent resistance to chemical attack and corrosion Applicable in water or chemical liquid Possible to use OILES 250 material for machining (Contact us for details of handling procedure)

(Note 1) Base material:chip, other : Base material: sheet form In the case that material form is chip, above values are measured perpendicular and parallel directions to forming, for tensile/compressive/impact strengths, and for bending strength, respectively. In the case that material is sheet, values are measured in perpendicular and parallel directions to layer, for bending/compressive/impact strengths, and for tensile strength, respectively.
