Shim rings, DIN 988: 3×6 to 50×63 bore and outside diameter, standard thicknesses

What bore and outside diameter sizes and thicknesses does a DIN 988 shim ring come in? · Standard part · basis: Westfield Fasteners' DIN 988 tables (nominal d1/d2 and standard thicknesses), cross-checked against Würth and Böllhoff DIN 988 listings (e.g. 12×18, 60×75)

Also called: din 988 sizes, shim washer 10x16, 12x18 shim ring, din 988 thicknesses, shaft shim 20 mm

Exact dimensions. Every file is drawn at true size with no tolerance added. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your process's clearance before making the part. Mating features

Notes

  • Columns: bore d1, outside diameter d2. Standard thicknesses: 0.1, 0.15, 0.2, 0.3, 0.5, 1.0, 1.1 to 2.0 in 0.1 steps.
  • Files drawn at s = 1.0 for every bore up to 50 mm; other thicknesses change s only. Larger sizes (52×65 to 170×200) are in the standard but not drawn here.
