Detailed Product Description
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 G2
2)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 is 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*8
Certification: Passed ISO9001 / 2000
