Professional circular separator spacer between recoiling sheet

Disc separator is used to separate slitted strips of coiling sheet of Aluminum, Copper, Stainless, Q235, and so on. To ensure no interference between neighbor rolls while rewinding process. Well used materials of separator disc: 65Mn, GCr15, 9SiCr, SKD11. Super hardness,bur free,high wear resistance and long work life are the merits of our knifes and spacer discs.

High quality disk metal steel spacer of slitting line

Matel spacer is used on slitter shaft to adjust different distance between slitting knife according to needed width of coiling strips. Same high pricision as slitting knife's; Reasonable price, not as expensive as knifes; Wear resistance, but lighter for machine shaft to ensure higher precision of slitting strip and easier assembling. Detailed parameters: 1. Basic size (ODxIDxTmm): 140x100xT 2. Material: 65Mn 3. Hardness: 48-58HRC 4. Tolerance of Thickness: +/-0.002mm 5. Burr-free 6. Roughness: Ra0.2/ Ra.04
