Tedin’s Advantages:
1. Self-developed roller production line:
Roller generatrix is modified by the logarithmic curve.
Reduce the stress concentration at the edge of the roller.
Increase bearing service life.
Precise control of roller roundness and contour.
Roller accuracy can reach to Grade 1.
Group diameter variation: 0.001mm;
Outer diameter waviness: 0.00015;
Contour deviation: 0.0015mm;
Hardness: HRC 61-64;
2.Bearing outer ring with double ribs: Effectively withstand axial force.
3. With special design of cage structure.
4. High purity raw material: imported row material TIMKEN steel, OVAKO steel, BAOSHAN special steel, etc.
