Zylinderrollen

Needle and Roller 1) Needle FBX provides whole range of needles, the needle material is bearing steel, the hardness is HRC60 65, the surface roughness Ra is not more than 0.2.Needle marks: P stand for flat end needle, Y for round end needle is ignored. Example of mark: Falt end needle P2.5 x 9.8 G2 Round end needle 2.5 x 9.8 G22)Cylindrical Roller The dimensional range for FBX cylindrical roller: Dw: 3 30, Lw: 5 50; The roller material is GCr15, the hardness is HRC60 65; And the hardness is HRC60 64 the material is GCr15SiMn,; Surface roughness Ra is not more than 0.2. The cylindrical dimension tolerance, group diamerter and length vibration, corner dimension and tolerance, outline tolerance and surface roughness are all in accordance with national standdards GB/T4661. Examples of mark: Cylindrical Roller 5 x 8 +3/-15. This standing for the diameter is 5, the length is 8, tolerance grade is G3, the average diameter vibration is +3 μ m, group average length of vibration is -15 μ m.3)Pin FBX also mass-produces piston pin and other pin for powertool. It is normally made of bearing steel. The precision, surface hardness and roughness are all in accordance with the related industrial standards, or up to user's requirements. The marking method for pin refers to the cylindrical roller. It uses "Pin" directly for the type representation, then there is" Diameter * Length". Example of mark: Pin5*8Certification: Passed ISO9001 / 2000
