Spherical washers, DIN 6319 form C: M5–M48 bore, outside diameter, sphere radius, height

What are the DIN 6319 form C spherical washer dimensions (bore, outside diameter, sphere radius, height) for M6 to M48? · Standard part · basis: MISUMI's DIN 6319 form C table (d1, d3, h1, h2, r1), cross-checked against Halder EH 23050 data sheets (M6, M12, M16) and ameco's 6554xxxx tables

Also called: din 6319 c dimensions, spherical washer m12, self aligning washer m10 radius, din 6319 sphere radius, spherical washer for conical seat

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: thread, bore d1, outside diameter d3, rim height h1, total height h2, sphere radius r1. Halder lists the same values (e.g. M12: 13 / 24 / 1.1 / 4.6, R17).
  • Mates with a DIN 6319 form D (or G) conical seat to take up angular misalignment; form D seats are not drawn here.
